Water System

YCUA obtains your drinking water from the Great Lakes Water Authority (GLWA) water system. YCUA's source water comes from the Detroit River, situated within the Lake St. Clair, Clinton River, Detroit River, Rouge River, and Ecorse River watersheds in the U.S. and parts of the Thames River, Little River, Turkey Creek, and Sydenham watersheds in Canada.  With the Great Lakes as our water source and proven treatment technologies, the GLWA consistently delivers safe drinking water to our community.

YCUA operates the system of water mains that carries this water to your home’s service line.  In addition to distributing water to the founding member communities (the Township and City), YCUA also supplies water to Augusta Township, Pittsfield Township, Superior Township, and portions of York Township, Canton Township, and Van Buren Township.  The total population of the communities in the YCUA water service area is just over 151,000 people.

YCUA is responsible for operation and maintenance of the public water supply facilities within the Charter Township of Ypsilanti and the City of Ypsilanti. This includes approximately 24 miles of transmission mains, approximately 345 miles of distribution mains, 6 booster pump stations, 4 ground storage reservoirs with a total capacity of 15 million gallons and 2 elevated storage tanks with a total capacity of 1.25 million gallons.
