SERVICE AREA

With the establishment of the regional water authority in 2025, West Des Moines Water Works (WDMWW) now purchases all of the water it distributes from Central Iowa Water Works (CIWW).

In addition to being a founding member of CIWW, the Water Works operates A.C. Ward Municipal Water Treatment Plant for regional authority and has a water supply capacity of up to 18 million gallons per day to serve the needs of our growing community.

Our service area shown on the map below extends west from First Street to the west of Grand Prairie Parkway in Dallas County. It stretches south from University Avenue beyond HWY 5 into northern Warren County. Customers in blue shaded portion of the service area receive water produced by WDMWW at A.C. Ward, which uses a combination deep wells in the Jordan Aquifer and shallow alluvial wells. Customers in the northwest and southeast green shaded portions of the service area receive water produced by other CIWW operators, sourced primarily from the Raccoon and Des Moines rivers as well as the underground gallery in Water Works Park in Des Moines.
