The Department of Water Management delivers nearly 1 billion gallons of drinking water to residents of Chicago and 125 suburbs daily. We also remove waste water and storm runoff through the sewer system. Our mission is to efficiently provide the highest quality drinking water to the Chicago region while protecting our most precious natural resource- Lake Michigan.

Prevent Pipes from Freezing 

It's freezing season and DWM wants to remind you that a few simple steps can prevent lots of costly damage.

To prevent pipes from freezing:

  • Maintain proper heat in your home.
  • Make sure there is warm air circulating in any area where there are water pipes. This includes garages and unheated areas of your home.
  • Insulate pipes, particularly those outside or on the perimeter of the house.
  • Remove all garden hoses from hose bibs and cover the bibs with Styrofoam insulating caps. 

If pipes do freeze, do not use candles or any open flame to thaw them. Try a hair dryer or heating pad instead.


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.
