Where do we get our drinking water?
Duncanville’s drinking water is obtained from surface water sources and has maintained its “Superior” water quality rating. Our surface water supplies are purchased from the City of Dallas. Dallas treats and uses surface water from seven sources: Elm Fork of the Trinity River, and lakes Grapevine, Lewisville, Ray Hubbard, Ray Roberts, Tawakoni, and Fork. Lake Palestine is currently in the process of being connected to Dallas’ system, with an anticipated connection date of 2027.
