Water Supply Information

Drinking water in University Park is provided by the Dallas County/Park Cities Municipal Utility District (MUD). The MUD is a special-purpose local government governed by an elected five-member Board of Directors. The MUD operates a treatment plant at 1811 Regal Row, Dallas TX 75235, that provides all treated water for University Park and Highland Park.

University Park's water originates in Lake Grapevine, where raw water is released and travels to the MUD's Regal Row plant. The water then goes through a series of carefully controlled steps, including:

  • Screening: The raw water passes through a mesh screen that removes large solids.
  • Flocculation: Chemicals, including calcium carbonate (lime) and ferric sulfate, are added to the water. The chemicals soften the water, reduce taste and odor, and promote the coagulation of molecules into large particles. The water is pumped into flocculation (large concrete basins) with mechanical paddles that agitate the water.
  • Clarifying: Next, the water passes to two 2-million-gallon clarifier tanks, which act as settling basins. Heavier particles of material settle to the bottom, and the remaining water flows into the final treatment stage. The heavier particles (sludge) are pumped to lagoons where the sludge settles and water is removed and pumped to the head of the plant.
  • Filtration: The water passes through eight filter units containing granular activated carbon sand, and four sizes of rock. The filtered water is then filtered again through ultra-fiber membranes, making it some of the purest water in the state. Chlorine and ammonia are then added for final disinfection. The finished water is stored on-site in a 10 million-gallon underground storage tank. When needed, the water is pumped out of the plant to the University Park pumping station in Germany Park. From there, the water enters UP's distribution system, which carries the water to each home or business and the City's two 2-million-gallon elevated storage tanks.

Federal law requires that public providers of drinking water issue an annual Consumer Confidence Report (CCR). The CCR contains information about water quality and test results for contaminants or other constituents.
