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.

University Park Lead and Copper Program

The City of University Park provides our customers with safe and reliable drinking water purchased from the Park Cities Municipal Utility District.  Our water meets or exceeds all drinking water regulations and is rated a Superior Water System, the highest rating offered by the Texas Commission on Environmental Quality (TCEQ). The City, through its Mile per Year program has been replacing old mains and service lines since 1989.  The district’s water treatment process also employs corrosion control strategies to prevent lead from leaching into water. 

What is lead?

Lead is a naturally occurring element found in small amounts in the Earth's crust. While it has some beneficial uses, it can be toxic to humans and animals, negatively affecting their health. Lead can come from many sources such as air, water, soil, consumer products, food, and occupational settings. 

Lead can enter drinking water when pipes and plumbing fixtures that contain lead corrode, especially where the water has high acidity or low mineral content. 

EPA's Lead and Copper Rule Revisions

Federal and state regulatory standards have helped reduce the amount of lead in our environment and minimize lead exposure. On January 15, 2021, the Environmental Protection Agency (EPA) published the Lead and Copper Rule Revisions (LCRR). Among its requirements, the LCRR requires all public water systems to submit an initial Service Line Inventory on October 16, 2024, and to provide periodic updates over the next ten years until the inventory is completed. 

As part of this requirement, the City has been reviewing existing documentation including plumbing codes, permits, historical capital improvements, distribution system maps and drawings, inspections and records of the distribution system and any other water system records that indicate the material composition of the service line connections. The inventory includes public and private service lines connected to the distribution system and categorizes the material of each service line. 

What is a service line?        

The service line connects the water main to a private property, such as a home or business. There are three basic parts to the service line: the public side, maintained by the utility; the meter, maintained by the utility; and the private side, which is the responsibility of the property owner. Property owners are responsible for maintaining the private side of the service line, including replacement of any lead plumbing inside their premise and along their property coming from the meter.
