The City of Darien supplies millions of gallons of safe, clean water every day to our customers. Our water quality exceeds the standards established by the United States Environmental Protection Agency (EPA) and Illinois Environmental Protection Agency (IEPA) Regulations. Per the IEPA, we are required to perform a "survey" of all water customers triennially to help protect the public water systems.
