​Water Utilities FAQs

​​​​Does DWU make a profit?

No, DWU is a not-for-profit City of Dallas department. DWU's budget is completely funded through the rates charged for water and wastewater services provided to customers. Rates are based on the cost of providing the services. The Department does not receive any tax revenues.

Why does Dallas supply water and wastewater services to other cities?

More than 20 nearby cities are wholesale water or wastewater customers of the City of Dallas. Wholesale customers pay the City of Dallas for the cost of the services and the wholesale customers, in turn, bill the individual people or businesses they serve. Everyone benefits from the savings associated with planning and building a system that serves several cities to meet common needs and goals.

Where does Dallas water come from?

Dallas' drinking water comes from six lakes: Grapevine, Lewisville, Ray Roberts, Ray Hubbard, Tawakoni and Fork.  Of the six lakes,  Dallas only owns and operates Lake Ray Hubbard.  Additionally, Dallas has water in in Lake Palestine, approximately 90 miles southeast of Dallas.  Lake Palestine is currently in the process of being connected to Dallas’ system, with an anticipated connection date of 2027.  The 2014 Dallas Long Range Water Supply Plan includes recommendation and alternative water management strategies to meet the Dallas’ and its customer’s needs through 2070.  These recommended water management strategies include conservation, reuse and new surface water.  Dallas also has up to date water conservation and emergency water management plans.
