Source of Water

Our water comes from through a purchase agreement with the Milwaukee Water Works, who performs all the necessary water filtration, treatment, and pumping to our city limits.

Our water rate structure is established under the guidance of the Public Service Commission of Wisconsin.

In addition to providing water for continuous daily demand by our residential, commercial, and industrial customers, we provide fire protection for the community by maintaining fire hydrants throughout the water distribution system.

Funding & Operation

The Wauwatosa Water Utility is a self-supporting enterprise fund with revenue coming from the sale of water and related services to our customers.

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.

Water Service Lateral Insurance

It has come to our attention that some insurance companies have been mailing flyers out to some City of Wauwatosa property owners.  The flyers describe how the customers are responsible for the repair of their water service laterals. The company proposes to provide repair or replacement coverage for leaking or broken water service laterals.

Property owners are responsible for their water service lateral from the curb stop valve outside (typically near the right of way line) into their house and past the water meter.  Property owners are encouraged to check with their insurance company to see if repairs are already covered.  Also, property owners considering coverage should carefully read the proposed terms of service coverage for what is actually covered.

We do not endorse any insurance company and are not affiliated in any way with these insurance companies nor their programs.
