Water


The Village provides water to approximately 17,000 residential and business customers.

The DuPage Water Commission (DWC) purchases Lake Michigan water from the City of Chicago and in turn, distributes and sells it to member communities, including Downers Grove.

Water supplied by the Village meets all Illinois Environmental Protection Agency (IEPA) standards, including those for lead.

Water Quality

The Water Quality Report summarizes information about where our water comes from, what it contains, and how it compares to U.S. Environmental Protection Agency (EPA) standards.

Lead Compliance

Lead pipes were banned by the U.S. EPA after 1986. Simply having a lead service line does not necessarily mean you have lead in your water. However, when a lead service line corrodes or is disrupted during maintenance, you may be at risk for contamination.


Water customers will receive notification from the Village regarding lead risks when one of the following occurs:

  • The replacement of a watermain within one block of your location.
  • The repair of a watermain break within one block of your location.
  • The replacement of your water meter.
