In Banff, like most other municipalities, storm water is not treated. Almost everything that goes into a storm drain flows directly into the Bow River.
Storm Water Pollution
Water from storm drains is a leading cause of river pollution, it can occur in two ways:
- Rainwater collects pollutants as it travels on paved areas and into drain. This is called storm water. Even small amounts of pollutants on roads, parking lots and sidewalks can be transported into nearby streams and rivers.
- People wash pollutants into the storm drains. The five most common household hazardous wastes found in storm water are:
- Automotive fluids (e.g. anti-freeze, brake fluid)
- All types of paints and stains
- Solvents (e.g. paint thinner)
- Fertilizers and pesticides (e.g. weed killer, pest spray)
- Cleaners (e.g. car cleaners)
