Source of Wheaton’s Water

Since 1992, the City of Wheaton has purchased Lake Michigan water from the DuPage Water Commission. The water is treated at Chicago’s Jardine Water Purification Plant, which is the largest potable water filtration plant in the world.

For water quality information, see the City of Chicago Department of Water Management website.

Homeowner’s Responsibility

In Wheaton, the homeowner is responsible for maintaining the valves on both sides of the water meter as well as all other interior plumbing. The owner also is responsible for all service leaks between the B-box or valve box in front of the house to the point the service enters the house.

The City maintains the water service between the B-box and the water main, and any leak in the water main itself.
