These pollutants within our watershed flow with storm water through the sewer system into creeks and drains and outfall into the Trenton Channel and Lake Erie. This type of pollution is called Storm Water Runoff Pollution and can be a major source of pollutants in our waterways that endanger wildlife, recreational use, and drinking water.
Storm water runoff refers to seasonal rainfall flows and snowmelts in the spring. It is very noticeable during a heavy rainstorm when large volumes of water drain off paved areas. Runoff pollution can happen at any time of the year when excessive water use from irrigation, car-washing, and other sources carries trash, lawn clippings and other urban pollutants into storm drains. Even automobiles leaking motor oil 20 miles inland can still pollute the lakes.
Storm Water Runoff Pollution can include anything that washes into the storm drain from the community. Unlike water pollution linked to factories or sewage treatment plants; this type can come from:
The waterways of the Great Lakes begin in front of your home at the storm drains. The City's Storm Sewer and Drainage System are the uppermost part of the waterway and a major source of freshwater for the lakes.
