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, Lombard, 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 250 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.
Please take advantage of our website to gain easy access to our services and programs. We are excited about serving our customers, and expect our website to improve our level of service.
You're invited to
the District's Open House!
Saturday, October 4, 2014
9 a.m. to noon
Hosted at our Wastewater Treatment Center
Each year, we sponsor an open house at our Wastewater Treatment Center. The Open House is an excellent opportunity for the community to learn about wastewater collection and treatment and its critical role in improving water quality. We host hundreds of guests, including scout troops, school groups, environmental advocates, local officials, and anyone who is interested. Guided tours of our facility are provided. We are proud to demonstrate how the treatment process works, and even include the chance to see the native fish that thrive in our treated effluent.
