South Bend Wastewater Treatment Plant operates under a National Pollutant Discharge Elimination System permit issued by the Indiana Department of Environmental Management. This allows the plant to discharge treated wastewater to the St. Joseph River in accordance with the stringent permit conditions. South Bend’s plant is designed to treat an average flow of 48 million gallons per day and can treat at least 77 million gallons a day under high flow. In 2018, the plant treated more than 13 billion gallons of water. The solids produced at the plant are treated to levels that make them acceptable for use on certain farm fields.
Combined Sewer Overflow
South Bend has a combined sewer, meaning rain water and sewage often travel in the same pipes. When excess rain overloads these pipes, an event known as a combined sewer overflow (CSO) occurs, sending dirty water into the river. This is not unique to only South Bend, as it also happens in hundreds of cities throughout the United States. As required by federal regulation, the City is taking steps to upgrade its sewer system to end this practice and to improve its local water quality. Known as the Long-term Control Plan (LTCP), steps are currently being implemented and will be complete by 2031.
Two Phases of South Bend’s Long-Term Control Plan
As required by 40 CFR 122.38 Great Lakes Basin CSO, permittees are required to develop a public notification plan. View CSO a Public Notification Plan.
