− | + | In Minnesota, our storm sewer systems carry water directly to our lakes, rivers, and wetlands. This water does not go to a treatment plant before entering our surface water. To maintain fishable, swimmable, and drinkable water and prevent pollution from entering our waterbodies, only stormwater should enter a storm sewer system. If anything else, such as oil, chemicals, or sediment, enters the system it is usually an illicit discharge.
