Water Supply

Where Do We Get Our Drinking Water?

Most of the City of Irving’s water is pumped from Lake Chapman to Lewisville Lake and then treated for Irving by the City of Dallas. Irving owns water rights to water in Lake Chapman, which was previously known as Cooper Reservoir. Some of the City of Irving’s water is purchased directly from the City of Dallas to supplement the Lake Chapman water. The City of Dallas uses surface water from the following seven sources: Lake Ray Hubbard, Lake Tawakoni, Elm Fork of the Trinity River, Lake Chapman, Lake Grapevine, Lewisville Lake and Lake Ray Roberts. The City of Irving continues to search for water supplies.
