Rural water quality

Farmers understand the importance of a healthy environment for crop and livestock production. However, traditional farming methods may jeopardize water quality. The Rural Water Quality Program provides farmers with financial assistance to improve and protect water quality. It is administered by the Grand River Conservation Authority.


Use of sanitary and storm sewers

The Sewer Use bylaw 90-001 regulates and controls the discharge of water and wastewater into the sanitary and/or storm sewer distribution system. To help protect the environment and water quality, proper disposal of materials including pharmaceuticals, paints and chemicals is important. Proper disposal prevents potentially harmful materials from entering the waste water distribution system or waste water treatment plant operation, and ultimately the Grand River.
