The Downers Grove Sanitary District is responsible for providing sanitary sewer service for the Village of Downers Grove, the portion of the Village of Westmont west of Cass Avenue, and portions of Woodridge, Lisle, Oak Brook, and Darien, Illinois. We are a separate unit of local government, independent of the municipalities where we provide sewer service. We are not part of the Village of Downers Grove.
The Downers Grove Sanitary District was organized in 1921 under the State of Illinois' Sanitary District Act of 1917. Today we provide sewer service to 20,000 customers, including wastewater generated by more than 60,000 people and a number of commercial, industrial and institutional customers. We operate and maintain a sewer system with over 230 miles of sewer main, and a Wastewater Treatment Center with a design average capacity of 11 million gallons per day.
We are determined to provide extraordinary service to our customers. We have developed comprehensive programs to assist our customers to maintain their building sanitary service at a high standard of excellence.
