Dallas Water Utilities (DWU) provides our customers with safe and reliable drinking water.  DWU meets and exceeds all drinking water regulations and has been rated a Superior Water System, the highest rating offered by the Texas Commission on Environmental Quality (TCEQ). Over 46 years ago, Dallas began eliminating lead service lines and pipes that could leach lead into the water. Dallas' 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, DWU has been reviewing existing documentation including plumbing codes, permits, historical capital improvement or master plans, 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.

Customer Survey 

DWU will continue its efforts to update the Service Line Inventory by conducting visual inspections, and has prepared a customer survey to help gather data and feedback to fulfill this obligation effectively. The survey provides tips on locating and identifying the material of the water service line, including details on how it connects to the home or building. Participants can complete a brief questionnaire and are also encouraged to upload photos of their service lines.
