Wastewater Treatment

The City of St. Charles’s Wastewater Treatment Division is responsible for ensuring that all wastewater produced by City residents is properly treated and disinfected prior to its return to the environment. With 8 full-time employees operate and maintain fourteen intermediate pumping stations two wastewater treatment facilities. Both treatment facilities were designed and built according to the standards established by the Illinois Environmental Protection Agency and are capable of treating up to 9.7 million gallons of wastewater daily. In addition to process control and compliance monitoring, the City’s Environmental Laboratory Division monitors industrial activities and provides analytical data necessary to fulfill all reporting requirements as required by the Clean Water Act (CWA).

As a matter of good practice and prudent management the Waste Water Utility has completed a Facility Master Plan which is used by the Utility as a steering document and to help ensure that the Utility is on the correct course for the next decade. The Facility Plan can be viewed by selecting it from the documents collection box on the right hand side of this page.
