The City of St. Paul Park's storm sewer system has three at-grade outlets discharging to the Mississippi River.
Water collected by storm sewers is vulnerable to pollution. There are two sources of water pollution--"point" and "non-point".
Point sources are those that have a specific location, such as an industrial facility that creates polluted water as part of its manufacturing processes.
Non-point sources are those that do not originate from a specific location. They are the result of human activities and urbanization. Some examples of non-point sources of pollution are motor oil spots on a parking lot, salt and sand used on roads during the winter, construction waste, lawn fertilizer, pet and wild animal wastes and grass clippings.
The pollutants are carried into lakes and streams by water, such as rain or lawn watering. Runoff from rain, lawn watering, snow etc. carrying these pollutants routes to hard surfaces and streets which is then collected by the storm sewer system. Pollutants also seep into soil through infiltration, potentially affecting the ground water table located below ground surface.

If you see anyone discharging any material other than rainwater in roadside ditches or storm drains, please report it.
A rain garden is perennial garden designed to tolerate periods of wet and saturated soils. When it rains, storm water runoff from the street is directed to these gardens. For small rainfall events (less than 1 inch in 24 hours), the rain garden is designated to infiltrate stormwater into the ground. In this manner, stormwater runoff is reduced from the area and pollutants are taken up by the rain garden plants.
The Mississippi Riverboat Clean Up is in cooperation of the businesses, organizations and volunteers who recognize water stewardship is important to the future of our state.
Storm drain stenciling projects offer an excellent opportunity to educate the public about the link between storm drain system and drinking water quality.
