Lead service lines in Dallas, TX

Dallas's water systems serve about 1.6 million people across the city and surrounding areas. Whether lead service lines pose a risk in your neighborhood depends on which utility serves your address and how old your building's plumbing is.

What we know about lead in Dallas water systems

Lead service lines are pipes that connect the water main (buried under the street) to your home. They were commonly installed before the 1980s. The good news: Dallas Water Utility and other major systems serving the area have not reported confirmed lead service lines in their current inventories.

However, "not reported" doesn't always mean "confirmed absent." Some utilities may still be investigating their older infrastructure or have incomplete records. Texas requires water systems to maintain lead service line inventories, but older records are sometimes hard to locate.

Your building's age matters more than the utility

Homes and buildings built before 1980 are more likely to have lead service lines, even in areas where inventories show none. The EPA and CDC recommend testing your water if:

  • Your home was built before 1986
  • You have lead pipes or brass fittings visible in your basement
  • Your water comes out cloudy or discolored sometimes

Lead doesn't always show up in drinking water, and you can't see, smell, or taste it. A simple water test is the only way to know for sure.

How to get your water tested

Contact your local water utility directly—they can tell you whether your service line is lead and may offer free or low-cost testing. The five largest utilities in the Dallas area are listed below. If you're in a smaller city or suburb, your utility will have the same information.

You can also buy a home testing kit from a hardware store or hire a certified lab to test your water.

Next steps for residents

  • Find your water utility: Enter your address on this site or call your city's water department to confirm which system serves you.
  • Ask about your service line: Request the material of your service line from your utility. If it's unknown or lead, ask about testing or replacement programs.
  • Test your water: If your home was built before 1986, get a free or low-cost test through your utility or a certified lab.
  • Learn about treatment: If lead is detected, the CDC recommends flushing your tap and using cold water for drinking and cooking.

Common questions

Does Dallas have lead pipes in the water system?

Dallas Water Utility and other major systems serving the area have not reported confirmed lead service lines in their current inventories. However, some older homes and buildings in the area may still have lead pipes connecting to the street main. The best way to know is to contact your utility or test your water.

How do I know if my house has a lead service line?

Contact your water utility and ask for the material of your service line. They have records of older installations. You can also look in your basement for a dull gray pipe that's soft enough to scratch with a coin—that's often lead. A water test will tell you if lead is entering your tap.

Is it safe to drink tap water in Dallas?

Dallas Water Utility treats and tests water to meet federal safety standards. If you're worried about lead, a simple water test costs $20–50 and gives you a clear answer. If your home was built before 1986, testing is a smart precaution.

What should I do if my water has lead in it?

Contact your utility and a healthcare provider if anyone in your home is pregnant or under 6 years old. The CDC recommends using cold tap water for drinking and cooking, flushing your pipes before use, and considering a certified water filter. Your utility may also have replacement or treatment programs.
