Where Does Our Drinking Water Come From?

Ever wonder where your drinking water comes from or what is in it? How about ways to conserve water use and save money? Well this is the place to answer those and many other questions.

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 Treatment

The cities of Dallas and Fort Worth have treatment plants that treat and disinfect water to make it potable.
