The Downers Grove Sanitary District was organized in 1921 under the State of Illinois Sanitary District Act of 1917. Originally, our treatment facilities were located on Curtiss Street at what is now the site of Sterling North Park in Downers Grove. In 1954, we began construction of the existing Wastewater Treatment Center on our property on Walnut Avenue, just south of the Burlington railroad tracks, and were able to eliminate the original plant. We have made improvements to the plant on numerous occasions, including major expansions in the early 1970s and again in the late 1980s.
