Stormwater Pollution Prevention
Protecting the stormwater system and your business. Keeping our waterways clean.
Every time it rains or snow melts, the driveways, parking lots and outside areas of industrial, commercial, and institutional facilities and sites under development get a bath. Dirt, oil, gasoline, garbage, and other chemicals are washed into storm drains. Stormwater and the pollutants in it flow into our rivers through outfalls – the concrete drains you see along the river. Polluted stormwater can affect the health of our streams, rivers and the land surrounding them, as well as the health of the wildlife and fish that rely on them.
The Stormwater Bylaw outlines regulations that those responsible for construction and land development, utility construction and maintenance, and industrial and commercial activities must follow to prevent stormwater pollution. By complying with the bylaw, you can avoid fines and the need for costly clean-up, and help keep our stormwater system and waterways safe and clean.
