2.0 The Licensing Program

2.1 The Municipal Drinking Water Licensing Program

With the issuance of Drinking Water Works Permits and Municipal Drinking Water Licences, the Ministry of the Environment is transitioning from an approvals program referred to as the Certificate of Approval (C of A) Program for municipal residential drinking water systems to the new Municipal Drinking Water Licensing Program (licensing program).

2.2 Authorities to Establish, Alter, Use or Operate

Under the C of A Program, an approval (C of A) is required prior to the establishment or alteration of a municipal residential drinking water system. The C of A also serves as the legal authority to use or operate the system. Conditions placed on the C of A may relate to either the physical works or the operation of the system.

Through the implementation of the Licensing Program, the authority to establish or alter a system will be provided through a drinking water works permit (DWWP) and the authority to use or operate will be provided through a municipal drinking water licence (licence). The DWWP will also provide a description of the drinking water system.

Both of these instruments will contain Terms and Conditions similar to those in Cs of A. Conditions which may be placed on the DWWP will generally relate to the physical works, while conditions on the licence will generally be related to operational matters.

The licence to operate the system will have an expiry date which will be no later than the fifth anniversary of the day of issue of the first licence or the licence renewal date and will also contain a date which is the deadline for an application for renewal of the licence. The application date will not be less than 90 days before the expiry of the licence. The DWWP will generally not have an expiry date unless such a requirement is considered appropriate by the Director.

2.3 One Licence and One DWWP for Each System

A drinking water system is made up of all connected water works under common ownership. Under the licensing program, a single DWWP and a single licence will be issued for the entire drinking water system.

The DWWP will provide a description of the overall system, including treatment, storage, pumping and distribution and will include, when applied for, an authority to alter the system in a specified way, much in the same way that a C of A currently approves alterations. Once the first DWWP has been issued for the system, further alterations to the system will need to be authorized through specific amendments to the DWWP.

2.4 DWWP Structure

The DWWP consists of the following:

  1. Front Page

    • DWWP Number

      A DWWP number will be assigned to the first DWWP for the drinking water system and will remain unchanged over time for that system.

    • DWWP Issue Number

      As the DWWP is amended with changes to the contents of Schedule A or Schedule B the issue number will be incremented to reflect these alterations.

    • Owner Name & Address

      This will identify the owner of the drinking water system along with an address. In most cases this will be the name of a municipal owner of the system.

    • Director Signature and Date

      This is the signature of the Director authorized to issue or amend the DWWP. The date on the front page established the validity date of the DWWP.

  2. Schedule A — Drinking Water System Description

    Schedule A provides a tabular description of critical components of the drinking water system currently in service. As the Director is notified of additional components of the system coming into service, further to conditions of the DWWP, Schedule A will be updated and re-issued to reflect these changes.

    Watermains within the system are identified through reference to a document or electronic file representing a graphic depiction of the distribution system submitted in support of an application for the first DWWP or a licence renewal, and the description has been written in such a manner as to also include all watermains which will be added to the system further to authorizations provided by the Director in the DWWP or issued at a future date. This part of Schedule A describing watermains will not be continuously updated or amended as watermains are added, modified, replaced or extended, but will be amended on a cycle consistent with licence renewal at which time an updated graphical depiction of the distribution system will be required to be submitted.

  3. Schedule B — General

    Schedule B sets out conditions of the DWWP. These conditions will generally relate to the addition, modification, replacement or extension of the physical works and include such matters as; the disinfection of works before being placed into service, notification of the Director when specified components of the system are placed into service and authorization for specified future alterations.

    • Specified Future Alterations

      The Director may have provided conditions within Schedule B of the DWWP which authorize specified future alterations to the system.

      Compliance with the conditions would enable the owner to proceed with the specified alterations, which may include additions, modifications, replacements and extensions to the drinking water system without obtaining any further authorizations or approvals under the SDWA. These conditions may relate to such works as watermains, minor modifications and equipment with emissions to the air.

      The conditions may include limitations on the nature and extent of the alterations, and establish other requirements which must be met before proceeding such as meeting specified design or performance standards. The owner of the system may also be required to prepare and retain records of the alterations and verification of conformity with the conditions. The forms required for verification will be available from the ministry.

      Specified alterations not meeting the conditions may be permitted but would require an application and further amendment to the DWWP (through a Schedule C document) issued by the Director prior to proceeding.

  4. Schedule C — Authorization to Alter the Drinking Water System

    Upon the successful review of an application for an amendment to a DWWP to permit an alteration to the drinking water system the Director will authorize the alteration by the issuance of a DWWP Schedule C document. The Schedule C document will describe the alteration to the system being authorized, be signed by the Director and contain an issue number and date. Multiple Schedule C documents may be issued in respect of the system over time as further alterations to the system are authorized.

    The conditions of the DWWP and the licence will apply, as applicable, to the additions, modifications, replacements or extensions of the drinking water system authorized by the issuance of a Schedule C document. Other Schedules of the DWWP and licence will not necessarily be amended and re-issued with each Schedule C document unless the alterations being authorized by a Schedule C document require associated amendments to conditions of the DWWP or licence. In such cases the Director will initiate the required amendments and re-issue the amended instruments.

2.5 Licence Structure

The DWWP will consist of the following elements:

  1. Front Page

    • Licence Number

      A licence number will be assigned to the first DWWP for the drinking water system and will remain unchanged over time for that system.

    • Licence Issue Number

      As the licence is amended with changes to the contents of Schedule A, B, C or D the issue number will be incremented to reflect these alterations.

    • Owner Name & Address

      This will identify the owner of the drinking water system along with an address. In most cases this will be the name of a municipal owner of the system.

    • Director Signature and Date

      This is the signature of the Director authorized to issue or amend the licence. The date on the front page established the validity date of the licence.

  2. Schedule A — Drinking Water System Information

    Schedule A identifies information in respect of the drinking water system including the DWWP number, any permits to take water associated with the system, financial plan numbers, and a listing of all accredited operating authorities for the system.

    Schedule A also sets out an expiry date for the licence and a date on or before which an application for the renewal of the licence must be submitted.

  3. Schedule B — General Conditions

    Schedule B sets out general conditions of the licence primarily relating to the operation and performance requirements of the drinking water system. The general conditions of the licence also set out several terms and conditions that apply to both the licence and the DWWP, including definitions and a requirement that the drinking water system must be established, altered and operated in accordance with the conditions of the DWWP and the licence.

  4. Schedule C — System-Specific Conditions

    Schedule C of the licence contains system-specific conditions primarily related to performance requirements of the drinking water system. These will include such things as rated capacities of any treatment subsystems, any maximum flow rates restrictions through any unit processes, residue management discharge criteria, ultra-violet equipment performance, flow measurement and recording requirements, any additional sampling, testing and monitoring requirements beyond regulatory requirements.

  5. Schedule D — Regulatory Relief

    Schedule D of the licence sets out conditions provided for any relief from regulatory requirements that has been authorized by the Director.

The Ministry has produced a document entitled 'Overview Guide — Municipal Licensing Program (PIBS 2601e) which is available on the Ministry’s Drinking Water Ontario portal and should be referenced for additional information on the Licensing Program.

3.0 Purpose and Applicability of this Guide

This Guide is intended to provide guidance to owners of municipal residential drinking water systems in respect of:

  1. Amendments to an existing DWWP to enable an alteration (including an extension) to an existing system
  2. Amendments to an existing licence
  3. Renewal of an existing licence
  4. Revocation of a DWWP or licence
  5. The first DWWP and licence for a new drinking water system1

This guide does not address matters respecting:

  • Applications for fragmentation or regulatory relief for municipal or non-municipal systems.

    Further information on these matters can be obtained from:

    Guide for Applying for Fragmentation and Relief from a Regulatory Requirement - Municipal Drinking Water Systems and Non-Municipal Drinking Water Systems — March 2009.

  • Applications for a Certificate of Approval respecting existing drinking water systems for which a DWWP/licence have not yet been issued

    Further information on these matters can be obtained from:

    Guide for Applying for Approvals related to Municipal and Non-Municipal Drinking Water Systems — Revised November 2003.

  • Applications for the issuance of, or an amendment to a Permit to Take Water.

    Further information on these matters can be obtained from:

    Permit to Take Water Manual April 2005, and the;

    Guide to Permit to Take Water Application Form February 2006 (PIBS 5046e).

  • Applications for approvals in respect of non-municipal or non-residential drinking water systems.

    See Appendix C of this document for further information respecting potential approvals requirements for these systems

Non-Municipal & Municipal Non-Residential Drinking Water Systems

Possible Other Approvals Requirements

Pursuant to the provisions of the SDWA and O. Reg. 170/03, an approval, DWWP and a licence is not required for the establishment, replacement or alteration of a non-municipal drinking water system or a municipal non-residential drinking water system.

Under the Safe Drinking Water Act (SDWA) the definition of drinking water system includes any thing related to the management of residue from the treatment process or the management of the discharge of a substance into the natural environment from the treatment system. Components of the drinking water system undertaking these functions may also be considered sewage works under the Ontario Water Resources Act (OWRA) or fall under the purview of the Environmental Protection Act (EPA) for discharging a contaminant into the natural environment other than water.

While an approval, drinking water works permit or municipal drinking water licence is not currently required under the SDWA for works or components from categories of drinking water systems which are not large or small municipal residential drinking water systems, it is possible that components from these categories of drinking water systems which manage residue from the treatment process or discharges a substance into the natural environment may require an approval under the OWRA or the EPA.

Approvals under the OWRA or the EPA are administered by the Environmental Assessment and Approvals Branch of the Ministry of the Environment and further contact should be made with this branch if there is any question with respect to approvals requirements under these acts for drinking water systems which are neither large nor small municipal residential drinking water systems.

While every effort has been made to ensure the accuracy of the information contained in this guide, it should not be construed as legal advice. If proponents/users of this guide have any doubts or questions regarding legal aspects of the document, they should consult their legal counsel.

4.0 When Applications are Needed

4.1 DWWP Amendments

Once a DWWP/licence has been issued for a drinking water system, any further alterations to the system (including additions, modifications, replacements and extensions) would be authorized through an amendment to the DWWP.

4.1.1 Exceptions

The following, however, represent exceptions to the above requirement:

  1. O. Reg. 170/03 exempts the following from the requirement to obtain a DWWP amendment before proceeding with the undertaking:

    1. the establishment or alteration of or a change to a service pipe;
    2. the establishment or alteration of or a change in an appurtenance of a watermain, if the appurtenance does not disrupt the operation of the drinking water system that the watermain is part of;
    3. the relining of a watermain, if the new lining does not disrupt the operation of the drinking water system that the watermain is part of; and
    4. the replacement of an existing watermain with a new watermain that has similar dimensions and performance criteria and that is in the same or approximately the same location, if the existing watermain was established or altered in accordance with an approval granted by a Director.
  2. The DWWP may contain an authorization for future specified alterations to the drinking water system subject to conditions imposed within the permit in which case the an application for the specified alterations would not be required before proceeding with the undertaking.
  3. Maintenance or repair of the drinking water system.

The owner may also apply for an amendment to the DWWP, or the conditions associated the DWWP, at any time for their own purposes.

4.2 Licence Amendments

In most cases the owner of the system would apply for a DWWP amendment only to authorize an alteration to the physical system. If the permit amendment would require a related amendment to the licence, respecting the operation of the altered system, the Director, at his or her initiative, will make the necessary amendments to the licence and its conditions.

The owner may, however, have reasons to request specific amendments to the licence as part of seeking the authority to alter the system through the DWWP. In such cases, the application for amendment to the licence should be submitted at the same time as the application for the DWWP amendment.

The owner may also apply for an amendment to the licence, or the conditions associated with the licence, at any time for their own purposes.

4.3 Licence Renewals

The SDWA requires that every licence be renewed within a five year period. The licence will identify its expiry date and a deadline for the submission of applications for renewal of the licence. The expiry date for a licence issued or renewed will be no later than the fifth anniversary of the day of issue or previous renewal of the licence.

The deadline for application for a renewal of the licence will not be less than 90 days before the date of expiry of the licence and will also be identified on the licence. The licence must be renewed to authorize the continued operation of the drinking water system beyond the expiry date set out in the licence.

4.4 DWWP and Licence Revocations

The owner of the system may apply for a revocation of a DWWP and/or licence for their own purposes. This revocation would apply to the DWWP and/or licence for the entire drinking water system.

If a component of an existing system, even a major component, were to be decommissioned and taken out of service such an alteration to the system this undertaking would be addressed through amendments to the existing DWWP and licence and not a complete revocation if other parts of the system remain in service.

4.5 New System Applications

The SDWA states that no person shall establish a new municipal drinking water system except under the authority of and in accordance with an approval (C of A) or a DWWP.

A new drinking water system would be a system for which no components of the system previously existed. Major treatment works additions or expansions, or watermains servicing a new subdivision would not represent a new system if they were to connect to any part of an existing system.

A non-municipal drinking water system, the ownership of which is being transferred to a municipality, should be regarded as a 'new' system for purposes of applying for a first DWWP and Licence.

The combined provisions of the SDWA and O. Reg. 170/03 require that a person who proposes to establish a new municipal residential drinking water system must apply for:

  • an approval (Certificate of Approval) for the system if the application is made before the date prescribed in O. Reg. 188/07 for the owner of the proposed system, or
  • a DWWP and a licence for the system if the application is made on or after the date prescribed in O. Reg. 188/07 for the owner of the proposed system.

5.0 Who Must Apply

5.1 Existing Drinking Water System

The responsibility for obtaining a DWWP amendment to authorize an alteration (including an extension) of a drinking water system and to ensure a licence is in place for the operation of the altered system lies with the drinking water system owner as identified on the current DWWP and licence.

5.1.1 Owner Definition

The SDWA defines 'owner' to include every person who is the 'legal' owner or the 'beneficial' owner of all or part of the drinking water system.

The legal owner is the entity who holds legal title to the physical works which make up all or part of the system. For most or all of any system this would generally be the municipal owner of a municipal drinking water system identified in the DWWP and licence.

The legal owner of a part of the system, however, could also be the owner of parts of the system designated as a municipal drinking water system through the provisions of O. Reg. 172/03. O. Reg. 172/03 prescribes parts of drinking water systems that serve major residential developments and are to be transferred at some future date from a developer to a municipal entity pursuant to a subdivision agreement to be municipal drinking water systems. Typically these would be watermains within a new subdivision, the ownership of which have not as yet been transferred to the municipality. These watermains will form part of the drinking water system.

The beneficial owner of all or part of a drinking water system is the entity who ultimately enjoys some of the benefits of ownership of the drinking water system, but does not hold legal title to it. In the above scenario of watermains, the municipal owner is a beneficial owner since it will ultimately be transferred legal title to the watermains through the subdivision agreement.

Authorizations to proceed with the addition of subdivision watermains will be issued to the owner of the parent drinking water system2, in most cases a municipality, who will be have either the legal or beneficial ownership of all parts of the system. In this context, the Ministry is also requiring that any applications for DWWP or licence amendments come from the legal owner of the parent system as set out in the DWWP and licence.

The provisions of the DWWP and licence, including their conditions, will apply to both the legal owner and the beneficial owner of parts of the drinking water system as applicable. For example, watermains for servicing a subdivision may be added, replaced, modified or extended by a legal owner (not necessarily the municipal owner of the system such as a developer) if the relevant conditions of the DWWP have been met. These conditions include, in part, that consent has been given by the beneficial owner of the drinking water system as identified in the DWWP and licence.

Enforcement of non compliance with any conditions of the DWWP or licence will be undertaken in respect of the appropriate party having committed the offence. One of the conditions of the DWWP will be that the owner of the system (as identified in the DWWP and licence) shall notify the legal owner of any part of the drinking water system that is prescribed as a municipal drinking water system by section 2 of O. Reg. 172/03 of the requirements of the DWWP and the licence as applicable to the prescribed system.

5.1.2 Licence Renewal

The owner of the drinking water system, and holder of the current licence, will be required to apply for a licence renewal.

5.2 New Drinking Water System

The proponent of the new municipal residential system should be applying for the DWWP and licence. In most cases this will be the future municipal owner of the system that is the beneficial owner of the system, as described above.

This scenario does not refer to the transfer of portions of a drinking water system being transferred to municipal ownership through a development agreement as these are municipal drinking water systems at the time of initial construction.

6.0 When to Apply

6.1 System Alterations and New Systems

In order to reduce the risk of unforeseen delays associated with obtaining the required DWWP amendment, when contemplating an undertaking, the proponents should familiarize themselves with the specifics of the DWWP/licence process and the requirements related to the supporting information and documentation for various types of proposals outlined in this Guide. Also, at that time, the proponents should contact the Ministry to determine the current application average turn-around time and schedule their projects accordingly.

The application average turn-around time will vary depending on the type of application, complexity of the project, and the number of other applications received by the Ministry in the preceding period. Proponents must also be aware that the application average turn-around time that would be provided by the Ministry on request would be based on the assumption that the application is complete. If, during the review of the application it is determined that additional information of documentation is necessary for proper assessment of the proposal, the review may have to be suspended and delay the issuance of the DWWP/licence amendment. If the required additional information is not readily available from the proponent, the application may be returned to the proponent as incomplete, and the proponent would have to re-submit the application when all required information is available.

6.2 Licence Renewal

As noted above, the expiry date for a licence issued or renewed will be identified in the licence will be no later than the fifth anniversary of the day of issue or previous renewal of the licence.

The deadline for application for a renewal of the licence will not be less than 90 days before the date of expiry of the licence and will also be identified on the licence.

7.0 Where to Apply and What to Include

Applications for DWWPs, DWWP amendments, licences, licence amendments, licence renewals, DWWP or licence revocations related to municipal drinking water systems should be made to:

Director, Part V, SDWA
Safe Drinking Water Branch
Ministry of the Environment
40 St. Clair Avenue West, 2nd Floor
Toronto, Ontario
M4V 1M2

A completed application form, together with the required supporting information and documentation, and the correct application fee (if applicable) must be submitted to the Safe Drinking Water Branch.

  • one (1) copy of the completed application form, including the supplementary forms referred to in the application form and provided in the application package (see Part II of this Guide for explanations),
  • all applicable supporting technical information and documentation outlined in Part III of this Guide,
  • the correct application fee (where applicable), and
  • a covering letter addressed to the Director, Part V, SDWA, at Safe Drinking Water Branch, stating the purpose of the application and indicating that a copy of the complete submission has been sent to the appropriate local District Office of the Ministry.

A copy of the application must be submitted to the Ministry’s District Office serving the area in which the system is or is to be located [see Appendix A - Regional, District and Area Offices of the Ministry for locations and addresses of the Ministry’s District Offices] as follows:

  • one (1) copy of the completed application form and all supporting information and documentation, and a copy of the covering letter.

A Note about the 'Transfer of Review Program'

The Transfer of Review Program is a program currently associated with the issuance of Certificates of Approval respecting sewage works and drinking water systems. The types of drinking water works covered by the program depend on individual agreements between the Ministry and the designated municipal authority, and they usually include watermains and water booster pumping stations. Under this program designated municipal authorities conduct a review of the application for approval on behalf of the Ministry of the Environment. The municipal authority then submits the application to the Ministry together with their recommendations for approval, or comments explaining why an application is not recommended for approval. Any fees associated with the review are collected and retained by the reviewing municipality. A further explanation of the program including a list of participating municipal authorities is contained within the Ministry’s Guide on Applying for Approvals related to Municipal and Non-Municipal Drinking Water Systems – Revised November 2003.

Until such time that a DWWP and licence has been issued for the system, applications for Certificates of Approval may continue to be submitted to the municipal authority participating in the program, however, once a DWWP and licence has been issued for a drinking water system the Transfer of Review Program will no longer apply to applications respecting the drinking water system.

The Transfer of Review Program will continue to exist for sewage works and will not be affected by the issuance of a DWWP or licence for the drinking water system.

The Ministry is intending to include an authorization for future specified alterations to the drinking water system in the DWWP subject to conditions imposed within the permit in which case the an application for the specified alterations would not be required before proceeding with the undertaking. It is anticipated that a significant portion of alterations including additions, modifications, replacements, and extensions of drinking water system components currently reviewed under the Transfer of Review Program, including watermains, will be pre-authorized through the DWWP.

Additions, modifications, replacements, and extensions of drinking water system not identified as being pre-authorized through the DWWP or additions, modifications, replacements, and extensions of drinking water system not meeting the conditions of the pre-authorization will require than an application be submitted and authorized through a DWWP amendment before proceeding with the undertaking. All applications respecting alterations to drinking water systems should be submitted the Director, Part V, SDWA at the Safe Drinking Water Branch for review and approval.

8.0 The Review and Approval Process3

The approval process generally consists of pre-application consultation, review of application, and issuance of approval. These steps are outlined below to give proponents an understanding of the process requirements and enable them to account for those requirements in scheduling their projects in order to avoid unforeseen delays.

8.1 Pre-Application Consultation

Pre-application consultation is a dialogue between the proponent, the Ministry, and possibly the public, prior to the submission of an applications for a new system or a significant DWWP amendment (although may be useful in the case of an application for a licence amendment or renewal).

In the case of a DWWP amendment, pre-application consultation is meant to assist proponents in defining the objectives, including environmental objectives, for the project in the case of a DWWP amendment. This may include determining the requirements regarding characterization of the source of raw water, any water treatment process waste stream effluent requirements, establishing general acceptability of the proposed technology, identifying any application type specific special information requirements (e.g., information in support of an application for relief from a specific regulatory requirement), and determining the need for public consultation/notification.

Pre-application consultation should be undertaken for all projects involving construction of new water 'greenfield' treatment facilities, expansion or re-rating of existing water treatment facilities, and major modifications/upgrades to existing water treatment facilities, and introduction of an innovative technology. Also, depending on their scope, it is recommended for less complex projects.

Where pre-application consultation is required or desired, it must be initiated by contacting the local District Office of the Ministry. The District Office may call upon or direct the proponent to other offices, branches or sections of the Ministry which may have a role in the approval process.

When approaching the Ministry, the proponent should be prepared to discuss the nature of the proposal and identify in general the proposed source of water supply, water treatment process, and any water treatment process residue management system and its expected effluent quality and environmental impact at the proposed discharge location. The Ministry will assist the proponent in identifying all provincial environmental legislation, policies, objectives and guidelines applicable to the project, including details of applicable public consultation and notification requirements under the Environmental Assessment Act (EAA).

The Ministry will also determine if there is a need for an assessment of the environmental impact of effluent from any water treatment process residue management system and outline the required scope of such an assessment, determine if a Permit to Take Water is required for the proposed system, advise on the required characterisation of the water source, and discuss with the proponent any special concerns that must be addressed in the application for approval.

Where the proposed system involves discharge of effluent from a process residue management system directly to the environment (i.e., other than into a sanitary sewer), it is recommended that the proponent completes the required environmental impact assessment and obtains a written concurrence with the assessment and proposed effluent criteria from the Technical Support Section of the respective Regional Office of the Ministry before the formal application for approval of the system is submitted to the Safe Drinking Water Branch.

If the required environmental impact assessment is only submitted to Safe Drinking Water Branch along with the application for approval of the drinking water system (without a confirmation of the concurrence with the assessment by the Regional Office of the Ministry), the Safe Drinking Water Branch will have to request the Regional Office to review the submitted assessment before commencing the review of the application for approval. However, if it is at that time determined that no pre-application consultation for the project took place, and the Region’s Technical Support staff advises the Safe Drinking Water Branch that they are not able to assess the submitted impact assessment without further data or other information not readily available from the proponent, the application may be closed as incomplete, and the proponent would have to re-apply after completing a proper environmental impact assessment.

Also in pre-application consultation, the proponent may discuss with the Ministry the need for and the details of any study to determine if the source of the proposed ground water supply should be considered a ground water under the direct influence of surface water (GUDI), and what level of water treatment may be required.

Note: For the purposes of the treatment and monitoring requirements of the Drinking Water Systems Regulation made under the SDWA, a drinking water system that obtains water from a raw water supply that is ground water under the direct influence of surface water (GUDI) is deemed to be a drinking water system that obtains water from a raw water supply that is surface water. The regulation identifies specific situations where a source of water supply is deemed to be a ground water under the direct influence of surface water (GUDI), and the source must be considered as such unless there is a report by a professional engineer or a professional hydrogeologist that concludes that the source is not a GUDI. In case of drinking water systems subject to the DWWP and licence requirements (municipal residential systems) of the SDWA, the source can only be considered a non-GUDI source if the Director agrees with the conclusions of the report by a professional engineer or a professional hydrogeologist.

For the purposes of an application for DWWP for a new system or proceed with alterations of a drinking water system, the report concluding that a source is not a GUDI (or a GUDI with adequate in-situ filtration) must be prepared in accordance with the Ministry document entitled "Terms of Reference for Hydrogeological Study to Examine Ground Water Sources Potentially Under Direct Influence of Surface Water".

Based on such pre-application consultation, the proponent would be better prepared to develop environmental objectives for the project with a clear understanding of the Ministry’s requirements, complete any required public consultation process (especially any process required under the Environmental Assessment Act), design the system such that the Ministry’s requirements and public concerns are adequately addressed, and obtain any prerequisite permits.

Where applicable, the processes that must be completed, and permits that must be obtained before an application for approval of the drinking water systems is submitted to the Safe Drinking Water Branch, may include, for example, completion of the environmental assessment process under the EAA (normally Class EA processes), a Development Permit under section 24(1) of the Niagara Escarpment Planning and Development Act, and a Permit to Take Water under Section 34 of the OWRA.

8.2 Screening of Applications

Upon the receipt by the Safe Drinking Water Branch of the Ministry, applications are pre-screened for completeness of their application forms and presence of the applicable application fees.

If an application does not include the application fee (if applicable) or if the application form is incomplete (see Part II of this Guide for detailed instructions for the completion of the form), the application cannot be properly recorded in the Ministry’s electronic application processing and information management system. In such a situation, the application processor will attempt to contact the applicant by phone in order to obtain this critical information. However, if the application processor is unable to obtain this information from the applicant within three business days of the receipt of the application, the application is returned to the applicant, and would have to be re-submitted.

Each application which includes at least the administrative processing portion of the application fee (if applicable) and whose application form is complete undergoes detailed examination of the entire submission for adequacy of the submitted fee and presence of the required supporting information and documentation (see Part III of this Guide for information on the supporting information and documentation requirements.

Based on the results of the examination of the submission, a letter of acknowledgement will be sent to the applicant.

In the letter of acknowledgement, the application processor advises the applicant of any missing supporting information and documentation, details of any fee inadequacy, and the date by which the applicant must respond to the request for additional fee and/or information (usually two weeks from the date of the letter).

Note: If the applicant fails to submit the outstanding fee or address the request for additional information or documentation identified in the letter of acknowledgement within the time allowed, the Review Engineer (the application will have already been assigned to the Review Engineer) will initiate the process of cancelling the application and refunding the submitted application fee in the amount reduced by any applicable non-refundable portion of the fee as may be stipulated in the Minister’s Order for Drinking Water Works Permit Fees.

8.3 Technical Review of Applications

Detailed technical review of applications for new system or DWWP amendments assigned to a particular Review Engineer is conducted chronologically in order of their receipt by the Review Engineer and therefore, the technical review of a particular application will not normally commence immediately. However, in order to expedite the process, immediately after receiving the application, the Review Engineer will determine if the application requires any supplementary review (e.g., comments on the submitted environmental impact analysis from the Technical Support Section of the appropriate Regional Office of this Ministry, or comments of the local Drinking Water Inspector and if required, will request such a review without delay.

In the detailed technical review, the Review Engineer assesses the completeness and adequacy of the submitted detailed design documentation and other supporting information, the compliance of the proposal with the Ministry acts, regulations, policies, objectives, and environmental guidelines, the conformance of the engineering design to the principles of sound engineering, and the adequacy of controls and contingencies provided to facilitate the proper operation of the system.

In the process of this detailed review, the Review Engineer may determine that additional information, beyond that requested (if any) in the letter of acknowledgement, is necessary for proper assessment of the application, or that the application involves aspect which require submission of an additional fee. A request for such information/additional fee is usually made in form of a letter or e-mail from Review Engineer to the applicant, and includes a deadline for response. This deadline may vary depending on the nature of the requested information but typically the proponent is given two weeks to respond.

Note: If the applicant is unable to submit the requested information within the given time but wishes to keep the application active, by the same deadline, the applicant must request an extension of the deadline and provide an adequate justification. If the applicant fails to respond to the request within the given time, or if the requested deadline extension is unjustified or unreasonably long, the Review will initiate the process of cancelling the application and refunding the submitted application fee in the amount reduced by any applicable non-refundable portion of the fee as stipulated in the fees regulations and any additional amount determined based on the Ministry’s effort expended to date in the review of the application. The applicant would have the right to appeal such a refusal to the Environmental Review Tribunal.

Upon completion of the detailed technical review, when all outstanding issues have been addressed, the Review Engineer provides his/her recommendations on the application to the approving Director.

8.4 Issuance of a DWWP or Licence — Including Amendments

Upon considering recommendations of the Review Engineer, the approving Director shall, as he or she considers necessary for purposes of the SDWA:

  1. Issue the DWWP, DWWP amendment, licence, licence amendment or licence renewal, or
  2. Refuse to issue or amend the instruments, or
  3. Issue the instruments including such terms and conditions as he/she deems necessary.

Conditions imposed on the DWWP will typically relate to the physical works. They may also deal with such issues as time-limited authority, timing for upgrades to the system or a requirement to obtain some other approvals before proceeding with the undertaking. An example of the latter would be a DWWP, or DWWP amendment authorizing an undertaking to proceed, subject to the submission and acceptance of final plans and specifications for works.

Conditions imposed on a licence will typically relate to requirements respecting the performance, operation and maintenance of the system as well as monitoring and recording of specific indicators of water quality and environmental impact, and provision of contingencies to prevent and deal with accidental spills or upsets.

8.5 DWWP Subject to Final Plans and Specifications

When requested, in some special circumstances, the Director may grant a DWWP or DWWP amendment in principle for works whose detailed engineering design has not been finalized, provided that the design has advanced to the stage where all significant technical decisions having a potential to affect performance and/or environmental impact of the works have been already made.

The issuance of such an instrument would include a special condition prohibiting construction of any part of so approved works until the Director has received and approved in writing detailed engineering design drawings, specifications, and a final engineering design report containing detailed design calculations for that part of the works.

A request for such an approval will be considered if the entity financing or approving the financing of the project (e.g., the Ontario Municipal Board) requires the applicant to provide a proof of the Ministry’s acceptance of the proposal prior to their release or approval to release funds for the undertaking of the detailed engineering design.

Such an approval in principle, subject to a separate approval of final engineering design for the proposed system, or its part, may also be granted for a large project with agreed upon phased implementation of its various components, or a "design-build" project, i.e., a project intended to be implemented through a single contract between the proponent and a contractor who would both design and construct the works.

Requests for such staged approvals will only be considered where the proponent has included with the application for a DWWP or DWWP amendment an adequate written justification for the proposed course of action. It is highly recommended that, where the proponent intends to take this route, the issue be discussed in the pre-submission consultation.

The technical information and documentation required to be submitted in support of applications for various types of drinking water systems for such an instrument in principle is outlined in Part III of this Guide.

8.6 Appeal Provisions

Where the Director decides to impose any terms or conditions on a DWWP or licence, alter any terms or conditions of an existing DWWP or licence, refuse to issue a DWWP, licence or a DWWP amendment or licence amendment, or revoke a DWWP, revoke or suspend a licence, in accordance with the requirements of section 128 of the SDWA he/she will serve the owner of the drinking water system with a written notice of this imposition, alteration, refusal, suspension or revocation, including details of the owners right to appeal the decision to the Environmental Review Tribunal.

Under section 129 of the SDWA, within 15 days after being served with such a notice of a reviewable decision, the person notified may require a hearing by the Tribunal by a written notice served on the Director and the Tribunal.

The conditions imposed on a DWWP will typically relate to the physical works. They may also deal with such issues as time limited approval, timing for upgrades to the system or a requirement to obtain some other approvals before commencement of the construction of the conditionally approved system or its part. An example of the latter would be an approval subject to obtaining approval of the final plans and specifications for the conditionally approved work.

9.0 Public Access to Application Information

The release of information contained in application forms and documentation submitted in support of applications for approval is subject to the provisions of the Freedom of Information and Protection of Privacy Act. This Act defines what may, and what may not, be disclosed to the public, and is used to assess all requests for information contained in the documents on file with applications for approval.

The applicant should therefore identify all documents which are to be considered confidential and must provide detailed evidence in support of this claim. The applicant should refer to the exemptions from disclosure set out in sections 12 to 23 of FIPPA, and in particular, section 17, third-party information. This evidence will be one of the factors the Ministry would consider when making a decision regarding disclosure of specific documents on file.

10.0 False Information

Through a reference to section 138, it is an offence under section 140 of the SDWA to knowingly give false information to the Ministry in respect to matters under the Act or regulations.

Under sections 141 and 142, the penalties for this violation could result in fines of up to $50,000 for the first conviction and fines up to $100,000 and/or imprisonment up to one year for each subsequent conviction where the offence is committed by an individual, and $250,000 and $500,000 respectively where the offence is committed by a corporation.

Part II Instructions for Completing Forms

1. Owner of the Drinking Water System

A. Owner Name

This is the name of the owner of the drinking water system as it would appear on legal documents associated with the owner. This should be the same name as that appearing on the current licence and DWWP.

2. Owner Mailing Address

A. B. C. D. E. F. G. Address Information

These entries make up the address that the owner of the system wishes to use for the purpose of receiving correspondence associated with the applications. The address will need to include the street number, unit identifier, municipality, province and postal code as applicable. If the formal mailing address includes a post office box, rural route or general delivery it should be identified accordingly.

H. Attention, I. Position/Title, J. E-mail address, K. Telephone

Enter information into boxes H. and I. to identify a specific person, along with their position or title, within the owner’s organization that will receive the amended DWWP/licence. In the case of a municipal corporation, this should be the mayor, warden, reeve, clerk or deputy clerk.

The e-mail address and telephone number is also being requested to facilitate communications and the forwarding of the DWWP/licence or amendments.

3. Drinking Water System

A. Drinking Water System Identifier Name

In cases of a DWWP/licence amendment, licence renewal or DWWP/licence revocation for an existing system this would be the drinking water system name that current appears on the existing DWWP and licence.

In the case of a new drinking water system, the system name entered here should be a name that identifies the municipal residential drinking water system as a whole. This name will be used to identify the system on the DWWP and the licence. In most cases this may be a simple and logical descriptor such as the 'Broken Antler Treatment and Distribution System'. This name will be included in the DWWP and licence to identify the drinking water system.

B. DWWP Number, C. Licence Number

The applicant is required to enter the drinking water works permit number and the municipal drinking water licence number in the case of an existing drinking water system.

If the application is for a new drinking water system these boxes should be left blank.

4. Type of Application

A. Identify the type of application being made

The applicant should check the box, or boxes, which identify the type of application being made.

This section of the application form also provides instructions respecting which sections of the application form need to be completed depending on the type of the application.

A DWWP amendment would be relevant for any application to authorize an alteration (including an addition, modification, replacement or extension) to a drinking water system. Such an amendment could also refer to a request to amend any condition of the DWWP.

A request for a licence amendment would not normally be required when requesting a DWWP amendment to permit an alteration to a system. If a licence amendment would be required in support of a DWWP amendment, the Director would normally undertake this at his or her initiative. The owner may, however, request an amendment to any condition in the current licence for the owners own purposes, in which case this box should be checked.

A new drinking water system would be a system for which no components of the system previously existed. Major treatment works additions or expansions, or watermains servicing a new subdivision would not represent a new system if they were to connect to any part of an existing system.

Note:

This application form does not provide a check box for an application for relief from regulatory requirements or for fragmentation of the drinking water system. For such applications, reference should be made to the Guide for Applying for Fragmentation and Relief from a Regulatory Requirement - Municipal Drinking Water Systems and Non-Municipal Drinking Water Systems March 2009.

This application form does not provide a check box for an application for the first DWWP or licence for an existing drinking water system. For such applications, reference should be made to the Guide for Applying for the First Drinking Water Works Permit and Municipal Drinking Water Licence and Submission of Operational Plans October 2008.

The proponent may be a person that is both the beneficial and legal owner of the drinking water system or a person other than the beneficial owner (e.g. legal owner only) of the undertaking and the appropriate box should be checked.

The latter scenario would apply, for example, when a developer is proposing to construct and initially own watermains within a subdivision. In such cases the person (including a corporation) who will initially construct and be the legal owner of the works should be identified as the proponent of the alteration of the system.

C. Name of Proponent

This entry should be the name of the proponent if it is different than the owner of the parent drinking water system. The proponent may be a corporation or a person. The name should be the full legal name (corporate name or a person) of the proponent as it would appear on legal documents.

D. Proponent Contact, E. Position/Title

This would be the person Ministry staff would contact in the event further dialogue was required on information submitted with the proponent of the undertaking. If the proponent is a corporation, the position or title of the person should also be identified.

F. Employer/Company

If the proponent contact is engaged by an employer/company other than the proponent identified in C., the employer/company should be identified here.

G. H. I. J. K. L. M. N. O. Proponent Contact Information

These entries provide further contact information including e-mail address and telephone number.

6. Technical Information Contact

A. Name B. Position/Title, C. Employer/Company

This would be the person Ministry staff would contact in the event further dialogue was required on information submitted in support of the applications, particularly information of a detailed technical or design nature.

If the project has a formal name it should also be entered here for reference purposes.

B. Project Start Date, C. Start of Operations

The anticipated project start date and date of commencement of operation should be identified.

8. Undertaking Location Information

A. Location Description

The applicant needs to identify which of three location categories are relevant to the application.

Box 1. The first box would be checked if there is not an identifiable location associated with the application, such an amendment to a condition of the DWWP or licence. In this case no further boxes need be completed in this section of the application.

Box 2. The second box would be checked if the undertaking were to be located over such a large spatial area that an identified location could not be readily described, such as 5 km of trunk watermain. In this case, the location identifiers need not be completed (boxes B. through O.) but the remaining boxes (boxes P. through S.) should be completed as applicable.

Box 3. The third box would be checked if the undertaking were to be located at a discrete location which could be identified. In this case all of the remaining (boxes B. through S.) should be completed as applicable.

Part III Supporting Information Requirements

This Part identifies the information and documentation that may need to be prepared and submitted to the Ministry in support of applications for a DWWP, a licence, amendments to those instruments and a licence renewal for a municipal residential drinking water system.

1.0 DWWP Amendments

1.1 The Rationale - Public Health and Environmental Impact

The supporting information requirements for applications related to drinking water systems are based on the various aspects of public health and environmental impact that must be considered in relation to drinking water systems. These aspects include the public health issues related to the quality and quantity of the drinking water being supplied, the impact on the source of water related to the quantity of water taken, the impact on the receiver of waste water generated in the process of water treatment, and the environmental impact associated with any discharges to the air from the equipment associated with the drinking water system (e.g., diesel generators, air stripping of methane).

1.1.1 Quality and Quantity of Supplied Water

With respect to the quality and quantity of the drinking water being (or proposed to be) supplied, there is a need for an assessment of the microbial safety and chemical quality of the source of raw water and the capability of the drinking water systems to adequately treat sufficient quantity of raw water and supply the treated water to the consumer in accordance with:

  • the requirements of the Ontario Drinking Water Quality Standards Regulation (O. Reg. 169/03 under the SDWA);
  • the Drinking Water Systems Regulation (O. Reg. 170/03 under the SDWA), as well as
  • the Procedure for Disinfection of Drinking Water in Ontario adopted by O. Reg. 170/03 through reference.
  • Also, in this assessment, consideration should be given to the objectives and guidelines included in the Ministry document Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines, and the design guidelines contained in the reference documents listed below.

With respect to water sources which are deemed under O. Reg. 170/03 to be groundwater under direct influence of surface water (GUDI), the Ministry requires that where a hydrogeological assessment is undertaken for the purpose of proving that a source is not a GUDI source or that a GUDI source has adequate in-situ filtration and may not need chemically assisted filtration, the assessment is required to be prepared in accordance with the document:

  • Terms of Reference: Hydrogeological Study to Examine Groundwater Sources Potentially under Direct Influence of Surface Water - October 2001.
1.1.2 Design Guidelines

The following publications are recommended to be consulted in the design of drinking water systems:

  • Design Guidelines for Drinking Water Systems — 2008
  • Recommended Standards for Water Works (GLUMRB, 2007)6

The above publications are only guidelines, not regulated standards which would have to be adhered to in order to obtain a new or amended DWWP. It is not the intention of the Ministry to stifle innovation, and if the design engineer can demonstrate that all public health and environmental protection requirements can be satisfied on a consistent basis by the proposed works, such a proposal will be considered for approval.

The DWWP may contain conditions which authorize specified additions, modifications, replacements or extensions of the drinking water system including watermains. Such conditions may make reference to a compliance with a design 'standard' as a requirement of the authorizations. This is not to say that watermains not complying with the design standard would not be approved if an application were to be submitted, however, watermains which meet the requirements of the design standard, as well as the other conditions of the DWWP, would be authorized to proceed without any further approvals from the Ministry.

1.1.3 Quantity of Water Taken From the Source

Another aspect of the health/environmental impact analysis of a drinking water system is the analysis of the effect of the withdrawal of water from the water source at the proposed quantities and flow rates on the availability of water to existing users of the water source and the maintenance of the necessary base flow.

The acceptability of the proposed rate and quantity of water withdrawal from the proposed source of water supply is established by the Ministry separately from the drinking water systems approval process through the Permit to Take Water (PTTW) program administered by the Regional Offices of the Ministry.

This acceptability of the proposed rate and quantity of water withdrawal (i.e., the availability of the required amount of raw water), must be established before the drinking water system can be properly designed. For this reason, applications for approval related to drinking water systems involving a new water intake/well or an existing intake/well with a change in quantity or rate of source water should include a copy of an appropriate valid PTTW under Section 34 of the Ontario Water Resources Act (OWRA) or, at least, a proof that an application for such a PTTW has been submitted to the appropriate Regional Director of the Ministry.

Note: Normally, a DWWP and licence (or amendments) will not be issued for a new/expanded system until valid PTTW(s) is/are in place. In exceptional situations, a DWWP amendment for the system may be issued subject to a prohibition to commence construction of the system until the required PTTW is obtained.

1.1.4 Disposal of Effluent

The disposal of any wastewater generated in the process of the operation of a water treatment plant (e.g., filter backwash water or other process residue) is an aspect of the environmental impact of a drinking water system, and must be addressed in all proposals for the establishment, alteration or expansion of a drinking water system. An analysis of this aspect of environmental impact would involve establishment of effluent criteria acceptable to the appropriate Regional Office of the Ministry, and an assessment of the capability of the proposed residue management system to operate within the criteria.

Any effluent discharged into surface water or into or onto the ground is considered a sewage discharge. Under the SDWA, facilities related to the management of water treatment process residue and the discharge of the facility’s effluent to the environment are part of the drinking water system. For this reason, where the drinking water system is subject to the DWWP/Licensing requirements of the SDWA, such facilities are assessed and approved together with the drinking water system, and do not need to obtain a separate approval under section 53 of the OWRA as sewage works.

Where the proposed system involves discharge of effluent from a process residue management system directly to the environment (i.e., other than into a sanitary sewer), it is recommended that the proponent complete the required environmental impact assessment and obtain a written concurrence with the assessment and proposed effluent criteria from the Technical Support Section of the appropriate Regional Office of the Ministry before the formal application for a DWWP or amendment. Before undertaking any such assessment, the proponent should contact the local District Office (pre-application consultation) to establish the required scope and depth of such a study which may vary considerably depending on the intended receiver of the effluent.

Note: If the required environmental impact assessment is only submitted to Safe Drinking Water Branch along with the application for DWWP amendment for the drinking water system (without a confirmation of the concurrence with the assessment by the Regional Office of the Ministry), the Safe Drinking Water Branch will have to request the Regional Office to review the submitted assessment before commencing the review of the application for approval. However, if it is at that time determined that no pre-application consultation for the project took place, and the Region’s Technical Support staff advises EAAB that they are not able to assess the submitted impact assessment without further data or other information not readily available from the proponent, the application may be closed as incomplete, and the proponent would have to re-apply for approval after completing a proper environmental impact assessment.

1.1.5 Other Discharges to the Environment

Under the SDWA, facilities related to the water treatment process that may discharge contaminants to the environment (including air emissions and noise) are part of the drinking water system. For this reason, where the drinking water system is subject to the approval requirements of the SDWA, such facilities are assessed and approved together with the drinking water system, and do not need to obtain a separate approval under the Environmental Protection Act provided that the application for approval under the SDWA includes all information that would be required for an application for a Certificate of Approval (Air) in accordance with the Ministry’s Guide for Applying for Approval (Air), Section 9, EPA.

1.2 Applications for DWWP Amendments for Drinking Water Systems

It is recognized that the process of planning and engineering design of drinking water systems varies with the size and complexity of the undertaking, and not all items of documentation listed in the Supporting Information Checklist section of the application form may be required for a particular undertaking.

The multi-stage process of planning and design of a new large and complex municipal drinking water system will involve preparation of a number of separate documents including an Environmental Study Report (ESR - a requirement of the Class EA process under the Environmental Assessment Act), a Preliminary Engineering Report (which may be part of the ESR), a Design Brief (basis of detailed engineered design), Final Plans (engineering drawings), and Specifications (construction process, materials and equipment).

On the other hand, the design of a minor modification may only require preparation of a single engineering drawing with the basis of design and specifications included on the drawing itself.

The information required to be submitted in support of applications for a DWWP amendment to authorize an alteration to a drinking water system is outlined below in the form of individual documents normally prepared in the process of planning and design of complex drinking water systems. However, it is not necessary to submit such separate documents provided all pertinent information is included in the submission.

Note: When requesting an approval in principle for a drinking water system or drinking water system component whose detailed engineering design has not been finalized, i.e., approval subject to approval of final plans and specifications (see Part I of this Guide for information as to when such an approval may be issued), the application should contain, as a minimum, the information outlined below under the heading Preliminary Engineering Report

1.2.1 Preliminary Design Report

If a Preliminary Design Report is being prepared for the proposed works, it should present the following information, where applicable:

  • Description of the proposed works, and where applicable, a description of the associated existing drinking water system which is intended to be part of the new/expanded system.
  • Extent, nature and anticipated population of the area to be serviced, facilities proposed to serve the area (including identification of the sources of water supply), and provisions for future expansion of the system to include additional service areas and/or population growth.
  • Itemization and discussion of present and future domestic water consumption figures, commercial and industrial usages, and fire flows used in sizing various components of the drinking water system.
  • Discussion of quantity requirements and its availability from the proposed source of supply based on a source study. The extent of a study to determine availability of water will depend on the type and size of the water source, and should be completed in association with the application for a Permit to Take Water (PTTW) issued by the appropriate Director appointed under Section 34 of the Ontario Water Resources Act (OWRA). For all wells, the source study should be a hydrogeologist’s report establishing the wells' perennial yields, maximum short-term yields (i.e., 1 day, 7 days, 90 days) and recommended pump sizing based on a hydrogeologist’s rating of the long term yields of the wells. The hydrogeologist’s report should also deal with possible interference with other existing wells in the area and other natural environmental issues/impacts.
  • For systems using or intending to use groundwater wells as a source of raw water, an assessment of the source with respect to it being deemed a (GUDI) in accordance with the criteria set out in O. Reg. 170/03 should be undertaken and, if required, a report prepared under the Ministry document Terms of Reference for Hydrogeological Study to Examine Groundwater Sources Potentially Under Direct Influence of Surface Water. The designer should refer to O. Reg. 170/03 under which some groundwater supplies are deemed to be GUDI, unless a report prepared by a professional hydrogeologist or professional engineer concludes otherwise; and
  • Discussion of raw water quality with respect to treatment requirements to meet the Ontario Drinking Water Quality Standards Regulation (O. Reg. 169/03) under the Safe Drinking Water Act, 2002 and the Ministry document Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines (Technical Support Document), supported by a raw water characterization of parameters listed in the Technical Support Document on a number of raw water samples appropriate for the type of source.

    In case of a groundwater source, it is usually sufficient to base the study on several samples obtained during the well pumping tests conducted to establish the yield of the well(s). In order to establish a reliable database for a source, it is generally necessary to undertake a water sampling and analysis survey extending over a sufficiently long period of time to account for seasonal variations in the water quality.

  • Normally, the source water analyses should include, at a minimum, all physical, chemical and bacteriological parameters identified in Tables 1, 2 and 4 of the Technical Support Document, and the gross alpha and gross beta screening procedure to determine if it is necessary to undertake further analyses to identify individual radionuclides responsible for the detected radiation (Table 3 of the Technical Support Document). Where general knowledge and/or historical data indicate that particular substances are consistently absent or below the level of concern, these substances/ parameters need not be included in the raw water characterization, provided that the designer documents evidence in support of such exclusion.
  • The raw water evaluation may also need to include parameters such as conductivity, water stability index, which are not listed in the Technical Support Document, but may be essential in establishing the raw water treatability or other special treatment needs.
  • Discussion of the proposed water treatment facilities for the treatment of the raw water in terms of the minimum treatment requirements of Drinking Water Systems Regulation (O. Reg. 170/03) under the Safe Drinking Water Act, 2002 and the Procedure for Disinfection of Drinking Water in Ontario (Disinfection Procedure) adopted by O. Reg. 170/03 through reference, and the treated water quality standards and objectives of O. Reg. 169/03 and the Technical Support Document, and a description of treatability work completed. This discussion should include a summary of basic process design parameters of all major components of the treatment facilities, including those such as chemical addition, equipment capacities, retention times, surface settling rates, filtration rates, filter-to-waste capability, and backwash rates as well as the operational reliability of key process units, unit redundancy and back up reliability.
  • Evaluation of treated water characteristics and their potential for accelerated corrosion of pipes and appurtenances in the existing or proposed distribution system and plumbing. (Refer to Design Guidelines for Drinking Water Systems 2008 - Section 5.1.1 — Blending of Dissimilar Waters/ Treatment Changes) if more than one water source is being considered.
  • Discussion of all residuals streams generated in the water treatment process, including their volumes, composition, proposed treatment and points of discharge, in terms of effluent criteria established by the proponent in concurrence with the appropriate Regional Office of the Ministry.
  • Discussion of the proposed instrumentation and control strategy and level of automation.
  • Discussion of the proposed flow metering, sampling and monitoring program, including monitoring of any waste streams.
  • Description of the proposed pumping facilities (well pumps, and low lift, high lift and booster pumping stations), including the number and capacities of duty and standby pumps, and discussion of the ability of the system to supply water during power failure events through either standby power facilities and/or elevated storage facilities.
  • Discussion of the system storage requirements, including disinfection capabilities and chlorine contact concentration/time (CT) requirements, if applicable, and the ability of the proposed facilities to satisfy these requirements.
  • Brief discussion of the locations of all significant water works structures with respect to proximity to sources of potential water supply contamination (e.g., sewage treatment plant discharges, sewer overflows, septic systems, impact of major storm events, tributary run-off impacts, runoff from agricultural/livestock rearing areas) and susceptibility to flooding.
  • Discussion of the design criteria used for proposed watermains including design flows, minimum and maximum distribution pressures, minimum depth of cover, and minimum separation distance from sewers and other utilities.
  • Discussion of the planning for any future extensions and/or improvements to the water supply and distribution system.
  • Preliminary design plan(s), all bearing the project title, name of the municipality/owner, name of the development or facility with which the project is associated, name of the design engineer and preparation date, and where applicable, the plan scale, north point, land surveying datum, and any municipal boundaries within the area shown, and providing the following information (where pertinent).
  • General layout and sizes of existing and proposed watermains, and location of major components of other existing and proposed water works and sources of water supply, and points of potential source or system contamination (e.g., sewage treatment plant discharges, sewer overflows, septic systems, runoff from agricultural/livestock rearing areas).
  • General layout (line diagram) of the works (except for watermains).
  • Process flow diagrams for the water treatment processes, showing all process components, the direction of flow of all raw and treated water, recycle and waste streams, the location of all chemical addition points, and the maximum flow of all streams entering and leaving each component of the process and a mass balance for all parameters around each process component; and
  • A drawing showing the hydraulic profile through the entire facility including each treatment process.

If these issues were addressed in the ESR, reference should be made to that document

1.2.2 Design Brief/Basis of Design

A design brief, summarizing the design criteria and presenting the design calculations used in sizing individual components of the system, should be prepared along with final plans and specifications. Where a preliminary report was not prepared or where some part of the information in the preliminary report is no longer valid or applicable, the design brief should include the applicable information outlined in as well as the applicable information outlined below.

1.2.2.1 Design Brief Watermains

In many cases, the establishment and alteration (including additions, modifications, replacements or extensions) of watermains will have been pre-authorized through the provisions of the DWWP. However, in cases where the pre-authorization conditions have not been met or are one of the excluded categories of watermains, an application for an amendment to the DWWP will be required.

In such cases, the design brief should include:

  • Nature and population of the area served (current and design);
  • Maximum water demand, including fire flows;
  • Hydraulic grade line profile;
  • Design data and calculations for individual watermains, including the required capacity; and
  • Capacity of the existing (or proposed) drinking water system to meet the additional water demand without compromising the system minimum pressure requirements. In cases of minor watermain extensions, where the minimum sizing requirement dictates the use of 150 mm (6 in) diameter pipes, such calculations are generally not required. However, the information is essential where:
    1. the designer proposes the use of pipe diameter smaller than 150 mm (6 in) for watermains not required to carry fire flow;
    2. the uncommitted water supply capability of the existing system is marginal; or
    3. the proposed water main extension is extensive.
1.2.2.2 Design Brief Major Facilities

Major facilities would include, but not be limited to, water intakes and low lift pumping stations, groundwater wells, water treatment plants, high lift pumping stations and water storage facilities. Basic data should be provided on the estimated water demand from the population and area to be served, including:

  • Process flow diagrams (PFD) showing all process components (including type, size, pertinent features, and rate capacity of process units and major equipment, e.g., tanks, reactors, pumps, and chemical feeders), direction of flow of all process, recycle, backwash and waste streams, and the location of all points of chemical addition and treated water and waste stream effluent sampling and monitoring; and indicating the minimum and maximum flow rates of all streams entering and leaving each process component as well as a mass balance for all parameters around each process component;
  • Proposed flow metering system, including raw water supply, backwash water flows, individual unit filtration rates, treated water production quantity;
  • Proposed chemical flow metering systems, where applicable;
  • Proposed treated water and waste stream effluent quality monitoring program, including provision of continuous automatic water quality analyzers, identification of sampling points, frequency of sampling and calibration procedures;

1.5 Detailed Description of Proposed Drinking Water System

The Ministry will be authorizing alterations to the drinking water system through the issuance of a schedule to the DWWP. That schedule will adopt a tabular format consistent with the system description schedule of the DWWP. It is intended to be a concise description of the authorized alterations containing the critical elements of the proposal.

In addition to the project description summary required to be provided in the application form, the proponent should attach a detailed technical description of the proposal clearly identifying all components of the system.

With the exception of watermains, such a detailed description would specify the locations, names, types, number, sizes and capacities of all vital structures and pieces of equipment in the proposed works, and identify the role of the individual components in the treatment process. The individual components of the system should be described in separate paragraphs in order of their sequence in the process flow.

Watermains should be described in a tabular form indicating the street on which the watermains are to be located and their location on that street with respect to the nearest intersecting streets.

The following are some examples of description of various types of drinking water system components.

2.0 Licence Renewal

The SDWA requires that the licence must be renewed within a five year period. An application for renewal will need to be submitted and the Director will issue a licence renewal if the Director is satisfied that:

  1. the system will continue to be operated by an accredited operating authority or operating authorities;

    The application for licence renewal will request confirmation from the owner of the operating authority or operating authorities for the system and the ministrywill confirm with the accreditation body that accreditation is still in place for authorities identified.

  2. the Drinking Water Works Permit remains in force;

    This information will be available to the Director through the Ministry’s own records.

  3. operational plans for the system satisfy the requirements of the Director’s Directions for Operational Plans;

    The application for renewal will be required the submission of the Operational Plan(s) for the system which will be reviewed by Ministry staff to determine whether they continue to meet the requirements of the Director’s Direction.

  4. financial plans have been prepared and approved;

    The application for licence renewal will request confirmation from the owner that the financial plans which have been prepared and approved by the owner as required under O. Reg. 453/07.

  5. the system has been and will continue to be operated in accordance with the requirements under the SDWA and the licence;

    This will be a judgement call on the part of the Director after considering all information available respecting the drinking water system. This will include any input from ministry’s inspection staff, performance of the system and the assessment of information provided in support of the application for renewal, including an assessment of raw water as a source water supply. Conditions on the DWWP or licence may be added or modified as part of this assessment.

    The raw water assessment will need to be undertaken as set out in accordance with Appendix C of this document entitled: Raw Water Assessment for the Renewal of the Municipal Drinking Water Licence.

  6. any required permits to take water remain in force (if required).

    The application for licence renewal will request confirmation from the owner of the status of any permits to take water for the system and MOE will share this information with MOE regional staff. This requirement would not be relevant for a stand-alone distribution system receiving all of its water from another drinking water system.

Part IV Statutory Framework

The Safe Drinking Water Act, 2002, c.32

There are different requirements set out in the Safe Drinking Water Act for municipal and non-municipal drinking water systems. The requirements are set separately in Part V (Municipal Drinking Water Systems) and Part VI (Regulated Non-Municipal Drinking Water Systems) of the SDWA.

These two parts of the SDWA set out general requirements and prohibitions regarding the establishment, replacement, operation, alteration and fragmentation of drinking water systems, including the Directors power to grant relief from regulatory requirements regarding water treatment, sampling, testing, monitoring of the systems and the reporting of results.

For the purposes of the SDWA and the regulations, the SDWA defines a "municipal drinking water system" as a system that is owned by a municipality or a municipal service board or a corporation established under the Municipal Act by a municipality or a group of municipalities, or from which a municipality obtains or will obtain water under a contract, or which is defined as a municipal drinking water system by a regulation. [Note: A drinking water system owned by a Local Services Board in an unorganized territory and serving a community located within an unorganized territory is not a municipal system.]

The Ontario Drinking Water Quality Standards Regulation (O. Reg. 169/03), made under the SDWA, sets the minimum drinking water quality requirements applicable to all water that is required to be "potable" under any Ontario act, regulation, municipal by-law, or an order or other document issued under the authority of an Ontario act.

The Drinking Water Systems Regulation (O. Reg. 170/03), made under the SDWA, categorizes drinking water systems and sets category-specific requirements related to the provision and operation of treatment equipment, conducting operational checks, sampling and testing, reporting adverse test results and other problems, taking corrective action, preparation of Annual Reports, and where applicable, preparation of Engineers' Reports, Engineering Evaluation Reports and Summary Reports for Municipalities.

The Definitions of Words and Expressions Used in the Act Regulation (O. Reg. 171/03), made under the SDWA, among others, defines the term "private residence". This definition is crucial in determining whether a drinking water serves a "major residential development" which makes the system subject to the requirements applicable to residential drinking water systems (e.g., approval requirements).

This definition provides that a "private residence" is a dwelling place occupied for an extended period of time by the same persons, if,

  • the residents have a reasonable expectation of privacy;
  • food preparation, personal hygiene, and sleeping accommodations are not communal in nature; and
  • any use of the dwelling place by a resident for a home occupation, trade, business, profession or craft is secondary to the use of the dwelling place as a residence and does not use more than 25 per cent of the indoor floor area.

Another provision of O. Reg. 171/03 relevant to the approvals program prescribes a non-municipal year-round residential system and a non-municipal seasonal residential system that serve a designated facility as a "regulated non-municipal system" for the purpose of subsection 52(2) of the SDWA (prohibition, fragmentation of regulated non-municipal systems). As a result, a Director’s consent is not required for fragmentation of a non-municipal non-residential drinking water system.

The Definitions of "Deficiency" and "Municipal Drinking Water System" Regulation (O. Reg. 172/03), made under the SDWA, defines the two terms noted in its name. The latter is especially significant from the point of view of the approval requirements. Through this regulation, the SDWA' definition of a "municipal drinking water system" includes, a residential drinking water system being established by a non-municipal owner under a Part VI Planning Act agreement with a municipality if the agreement provides that the ownership of the system may be transferred to the municipality.

The Licensing of Municipal Drinking Water Systems Regulation (O. Reg. 188/07) made under the SDWA provides schedules of dates on or before which the owner of a municipal residential drinking water system must apply for a drinking water works permit and a municipal drinking water licence; and must submit operational plans for the system to the Director. The regulation also established that the day a municipal drinking water licence is first issued to the owner of a municipal drinking water system is specified as the day on and after which the owner shall ensure that an accredited operating authority is in charge of the system.

The Financial Plans Regulation (O. Reg. 453/07) made under the SDWA sets out requirements for the preparation and content of financial plans for new and existing municipal drinking water systems.

Appendix C Raw Water Assessment for the Renewal of the Municipal Drinking Water Licence

1.0 Preamble

In a multiple barrier system for providing safe drinking water, the selection and protection of a reliable, high quality drinking water source is the first barrier.

The purpose of providing information respecting raw water in support of an application a Licence renewal, is for the owner to demonstrate to the Director that:

  • the source water has not substantively deteriorated or varied since the issuance of the issuance or renewal of the Licence, and
  • the existing unit processes of the treatment system continue to be appropriate and effective for the treatment of the source water.

2.0 Raw Water Categories

The concerns respecting the ongoing suitability of raw water sources and the current treatment being provided may be further summarized by source water category as follows:

2.1 Surface Water

A good groundwater supply should have no evidence of contamination by surface water7. The minimum treatment requirement for such supplies consists of disinfection only. The concern is that the system might have become, or might be trending towards, a Groundwater Under the Direct Influence of surface water (GUDI) designation.

2.2 Groundwater

Surface water supplies are presumed to contain some contaminants or be at a high risk of contamination and the applicable minimum treatment requirements consisting of chemically assisted filtration and disinfection have been established accordingly. The concern is that contamination upstream or in the vicinity of the intake might have increased or varied with time such that it could not be effectively removed or treated with the existing treatment processes. It is necessary to confirm that the current pathogen log removal or inactivation capabilities of the treatment processes continue to be adequate, which, in turn, will be based on confirming that the raw water supply has not significantly changed in its characteristics.

2.3 Groundwater Under the Direct Influence of Surface Water (GUDI)

A well water supply is a GUDI supply where there is:

  1. Physical evidence of surface water contamination (e.g. insect parts, high turbidity), or
  2. Evidence of surface water microorganisms (e.g. campylobacter, aerobic spores, cryptosporidium, giardia)

Also, subsection 2(2) of O. Reg. 170/03 specifies conditions under which well water is deemed to be groundwater under the influence of surface water unless a current report by a professional engineer or professional hydrogeologist states that the well is not a GUDI well and a MOE Director agrees with this conclusion.

A well water supply will normally be flagged as a potential GUDI system, and the undertaking of a study by a professional engineer or professional hydrogeologist may be necessary, if:

  1. The well water regularly contains Total Coliforms and/or periodically contains E.coli; or
  2. The well is located within approximately 50 days horizontal saturated travel time from surface water or are within 100 m (overburden wells) or 500 m (bedrock wells) of surface water (whichever is greater) and meet one of the following criteria:
    1. The well may be drawing water from an unconfined aquifer;
    2. The well may be drawing water from formations within approximately 15 m of surface;
    3. The well is part of an enhanced recharge/infiltration project;
    4. When the well is pumped, water levels in the adjacent surface water body rapidly change or hydraulic gradients in the ground beside the surface water body significantly change downward in the direction of the well;
    5. Physical and chemical water quality parameters (e.g., temperature, conductivity, turbidity, total dissolved solids, pH, colour, oxygen) in the well water are more consistent with the adjacent surface water body than the local groundwater and/or they fluctuate significantly and rapidly in response to climatological or surface water conditions.

A well water supply determined to be a GUDI supply is considered to have essentially the same risks as a surface water supply and, as such, the minimum treatment for GUDI supplies consists of chemically assisted filtration and disinfection. The concerns for this type of source water are the same as those outlined above for a surface water source.

2.4 GUDI with Effective Insitu Filtration

A water supply identified as a potential GUDI supply through the ministry review of the Engineer’s Report (submitted further to the requirements of O. Reg. 459/00) would have been determined by the Director to have effective in-situ filtration when all of the following conditions were met:

  1. particle count data had shown that water consistently contained significantly less than 100 particles per ml in the size range of 10 microns and greater in size;
  2. a hydrogeologist’s report had confirmed that the particle count is not likely to change during storm, seasonal or other regular environmental changes; and
  3. the raw water was characterized by good microbiological quality.

For GUDI sources determined to have effective in-situ filtration, the minimum treatment requirements imposed through conditions of the C of A would consist of enhanced disinfection alone and the system owner would also be required to take measures to protect the well from contamination and prevent deterioration of the integrity of the overburden in the vicinity of the well.

The concerns to be addressed during Licence issuance or renewal are whether the in-situ filtration provided by the overburden might no longer be effective or that any protective or preventive measures imposed by the C of A might not have been implemented.

3.0 Raw Water Characterization General

In the case of a new drinking water system raw water characterization would normally require results of source water analyses that include all physical chemical and bacteriological parameters identified in Tables 1, 2 and 4 of the Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines — Revised June 2006 (ODWSOG), or as further revised from time to time, which is published in support of the Ontario Drinking Water Quality Standards Regulation (O. Reg. 169/03) document. This characterization would also include the gross alpha and beta screening analyses to determine if it is necessary to undertake further analyses to identify the individual radionuclides responsible for the detected radiation and determine their individual radiation intensities8 (Table 3 of the ODWSOG document).

The number of samples and the period of sampling frequency would be dependent on the type of source. A new secure groundwater source may only require samples taken during well pumping tests, while a new surface water supply may require sampling over a period of time sufficient to account for seasonal variations in the water quality.

The raw water characterization may also need to include such parameters as conductivity, water stability index, etc., which are not listed in the ODWSOG document, but may be essential in establishing the raw water treatability or other special treatment needs.

4.0 Raw Water Assessment — Licence Renewal

For purposes of determining that the raw water has not changed significantly enough to warrant additional treatment, the information required to be submitted may be met, in whole or in part, through historical data or knowledge.

The information submitted should include, as a minimum, a summary9 of the following information compiled since the issuance of the first licence or the last renewal of the Licence (as applicable):

  • Monitoring results of raw water taken in accordance with regulatory requirements, or Conditions imposed on a C of A.
  • Monitoring results of raw water taken for purposes of operational control.
  • Results of any raw water assessment which may have occurred within the interim period.
  • In the case of a GUDI well supply which has been determined to have effective in-situ filtration (but without chemically assisted filtration as part of the treatment system), an outline of any measures implemented to protect the well from contamination and prevent deterioration of the integrity of the overburden in the vicinity of the well.

In addition, the submission may also include summary information or historical data including, but not necessarily restricted to:

  • Monitoring results of treated water where the parameters in question would not be significantly removed or altered by the treatment processes of the system,
  • Assessments or studies undertaken of the source water catchment area,
  • Knowledge of land use activities (e.g. no agricultural activity or pesticides application within the aquifer catchment area of a well supply).

The information submitted needs to demonstrate to the ministry reviewer, and in turn the Director that the treatment being provided (or proposed in the case of a new system) continues to be appropriate for the current source water conditions.

Where there have been some evidence or analysis results since the issuance of the first licence or the last renewal of the Licence (as applicable) that the raw water may have changed or would indicate evidence of a GUDI or potential GUDI source in a well supply previously identified as a good groundwater source, further discussion on the evidence or analyses results is required. In this case, the supporting information provided must include a discussion of relevant incidents or historical occurrences and measures taken to respond to or address the occurrences and/or results of any subsequent monitoring.

The ministry’s review staff may request further information to support the assessment of the raw water source.

If the applicant should have any questions respecting the sufficiency of the information being provided he/she should contact the Safe Drinking Water Branch for further pre-submission consultation.


1 A new drinking water system is one for which no components of a system previously existed and does not include any new works, regardless of size or complexity, being added to an existing system. A fully functional non-municipal drinking water system, the ownership of which is being transferred to a municipality, should be regarded as a ‘new’ system for purposes of applying for a first DWWP and Licence. This latter scenario does not refer to the transfer of portions of a drinking water system being transferred to municipal ownership through a development agreement as these are municipal drinking water systems at the time of initial construction.

2 In this context ‘parent’ drinking water system means the system, identified in the DWWP/licence, onto which the developer’s watermains will be connected.

3 In the meaning of the Safe Drinking Water Act, the term “approval” relates to the process associated with a Certificate of Approval. The use of the term here in the context of DWWPs and licences has a broader general meaning of a review and approval process.

4 This prohibition does not apply to specified future alterations which may be authorized through conditions in the DWWP; however, all other requirements of the EAA continue to apply to the specified future alterations.

5 An operational subsystem is the part of the drinking water system that is operated by an operating authority if there is more than one operating authority for the entire drinking water system. Any existing operational subsystems will be identified in Schedule A of the licence.

6 The Ministry is a member of the Great Lakes-Upper Mississippi River Board of State and Provincial Public Health and Environmental Managers (GLUMRB), and participates in the development of and subscribes to the Board’s recommendations for water works standards known as the "Ten State Standards". This document is specifically identified in the Ministry’s Procedure for Disinfection of Drinking Water in Ontario as a design guideline for drinking water systems in Ontario.

7 Procedure for Disinfection of Drinking Water in Ontario – June 4, 2006 – section 2.2

8 When such screening is undertaken and the results are confirmed to be above a set value, the individual alpha and/or beta emitting radionuclides responsible for the radiation detected through the screening analyses must be identified and their individual radiation intensities determined. The identification if individual alpha emitters is required if the repeat gross alpha analysis result exceeds 4.0 Bq/L (repeat analysis required if the first analysis result exceeds 0.1 Bq/L). The identification of individual beta emitters is required the repeat gross beta analysis result exceeds 0.5 Bq/L (repeat analysis required if the first analysis result exceeds 0.5 Bq/L).

9 The extent and content of the summary will vary from system to system and depend on the nature and availability of the information. While the individual analysis results need not be submitted, the summary should be supported by context information (e.g.: parameter, number of samples, frequency/period of sampling, ranges, averages, etc.) as available.
