Overview

Drainage is an essential service across Ontario for agriculture, roads, residential, commercial and industrial properties in both urban and rural settings.

Rural and agricultural drainage balances the needs of farmers and property owners with environmental and societal interests. It consists of a combination of private and communal drainage systems that eventually outlet into natural watercourses.
