Drinking Water


Where Does Our Drinking Water Come From? 

The City of Grand Prairie purchases most of its water from Dallas and Fort Worth. Of the purchased water, 90% comes from Dallas while the remaining portion comes from Fort Worth and services the northwest portion of town.

During most summers, the city has to turn on its groundwater wells to keep up with the demand brought about by warm weather. These wells typically service the areas of town that are within a 1–2 mile radius.

The water that Fort Worth delivers to Grand Prairie is taken from lakes Benbrook, Bridgeport, Eagle Mountain, and Worth and the Cedar Creek and Richland-Chambers Reservoirs. Dallas treats water from the Elm Fork of the Trinity River and lakes Ray Roberts, Lewisville, Grapevine, Ray Hubbard and Tawakoni. Click the below to see a map of these lakes.

Water Quality Reports

The U.S. Environmental Protection Agency (EPA) and the Texas Commission on Environmental Quality require that all public water systems produce annual Water Quality Reports outlining the quality of your drinking water. These reports, also called Consumer Confidence Reports (CCR), are due to the public by July 1 of the following calendar year. The icons below will lead you to pdf versions of this document.
