The Chicago Water Agenda defines a number of initiatives and policies to better conserve our fresh water and to wisely manage storm water. In this site we have gathered many resources to give you the information needed to help save our source water.

The Department of Water Management is responsible for delivering nearly 1 billion gallons of fresh pure water to the residents of Chicago and 125 suburban communities every day. We are also responsible for removing the waste water and storm runoff from the streets of Chicago through the sewer system, and delivering the effluent for treatment to the Metropolitan Water Reclamation District of Greater Chicago. All of this is accomplished through a network of purification plants, tunnels, pumping stations, water mains, sewer mains, valves and structures that require constant upkeep and maintenance.

 Flushing Your Water System 

Now that your old water main has been replaced and your water service has been connected to the new water main, it is important to flush your plumbing of any sediment, rust or metals, including any lead to maintain water quality.

Winter Weather and Your Water System

During the cold winter weather the job of thawing water services and frozen hydrants are endless tasks. We are asking for your assistance to help combat this seasonal problem, and perhaps to save yourself some aggravation.

  • Service lines and internal plumbing are the responsibility of the property owner, so check you indoor plumbing and make necessary repairs.
  • Secure basement doors and windows, to prevent cold drafts and protect pipes near exterior walls.
  • Report water leaks (parkway or street) and non-functioning or leaking hydrants to the Department of Water Management by calling 311.
  • In the event of a frozen service, report it to 311. When the water service is restored, please follow the instructions Department employees give to maintain a functioning service

Warning  Do not use an open flame to thaw water pipes. For additional information please call 311.
