Water Quality Report

The U.S. Environmental Protection Agency requires water utilities provide their customers a Consumer Confidence Report annually. This information is designed to educate our customers about the source of the water supply, the water treatment process, and the extensive testing conducted to ensure water quality before the water enters a property in Wauwatosa.

Fluoride

The Milwaukee Water Works treats their water with low levels of fluoride to prevent tooth decay. As the City of Wauwatosa receives their water from Milwaukee, there is fluoride in water provided through the Wauwatosa Water Utility.

Why does Milwaukee Water Works treat its water with fluoride?

You can find more information about fluoridation on the web sites of the Department of Health and Human Services, the Centers for Disease Control, and the Milwaukee Health Department. Fluoridation of water has been endorsed and affirmed by the American Dental Association, the American Medical Association, and the U.S. Public Health Service.

The fluoride level in water from the Milwaukee Water Works does not exceed 0.7 milligrams per liter and conforms to regulations. According to the Centers for Disease Control, the proper amount of fluoride helps prevent tooth decay and cavities for individuals of all ages.

Fire Hydrant Flushing

We flush fire hydrants twice each year in spring and fall and throughout the year if necessary. Hydrant flushing:

Improves water quality
Exercises hydrants so they are in good functioning order when needed for an emergency
Removes sediment that may cause discolored water
Allows us to inspect each hydrant for defects

If you do experience discoloration in your water, we recommend running the cold water for several minutes to help clear the discoloration before using it for drinking or laundry.
