Lead Service Lines in Texas

Texas serves over 33 million people through 7,139 water systems. The state has not yet reported data on lead service lines to the EPA—meaning public inventories of where lead pipes exist are not yet available.

What this means for you

If you live in Texas, your water utility does not yet have a public list showing whether lead service lines are present in your area. However, this does not mean there are no lead lines. It means the inventory work is still underway or data has not been shared publicly.

Lead service lines are pipes that connect the water main (under the street) to your home. If your service line is lead, water sitting in that pipe overnight or between uses can pick up lead. Homes built before 1986 are more likely to have lead service lines, though they can exist in any era.

What Texas utilities are doing

The largest utilities in Texas—including the City of Houston (serving nearly 3 million people), San Antonio Water System (over 2.1 million), and Dallas Water Utility (1.4 million)—are required by federal law to inventory their lead service lines and report findings to the EPA. That work is ongoing at most systems.

Texas has not yet received federal Bipartisan Infrastructure Law funding specifically for lead line replacement, though funding opportunities may expand.

How to find out about your home

Contact your local water utility directly. Ask them:

  • Do you have a lead service line inventory?
  • Is my address included in it?
  • What is the material of the service line to my home?
  • What is your timeline for replacement or testing?

If your water system does not yet have this information, ask when they expect to complete their inventory.

Protecting your water now

Until you know your service line material:

  • Let water run for 30 seconds to 2 minutes before using it for drinking or cooking (longer if the pipe is long or if water has sat overnight).
  • Use cold water for drinking and cooking—hot water dissolves lead faster.
  • Consider point-of-use filters certified to reduce lead (NSF/ANSI 53 standard).

If you have questions about health impacts, especially if children drink your tap water, contact your pediatrician or the CDC.

Next steps for residents

  • Contact your water utility and ask for lead service line inventory data for your address.
  • Ask about their timeline for inventorying and replacing lead lines.
  • Use the filter and flushing steps above while you wait for clarity.
  • If health concerns arise, speak with your doctor or call the CDC hotline.

More on lead pipes in Texas

Frequently asked about lead pipes in Texas

Does Texas have lead pipes in drinking water?

Texas has 7,139 water systems serving over 33 million people, but public data on lead service lines is not yet available. Lead pipes may exist, but utilities are still inventorying their systems. Contact your local water utility to ask about your specific address.

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

Contact your water utility and provide your address. They can tell you the material of your service line. If you can access the point where the line enters your home, a magnet test can help: lead is not magnetic, copper is not magnetic, but steel is. A plumber can also inspect for you.

Is it safe to drink tap water in Houston, Dallas, or San Antonio?

These cities serve millions of people and must test for lead under federal rules. While they do not yet have public inventories of lead service lines, you can contact each utility directly for information about your address and ask about their testing and treatment processes.

What should I do if I think I have lead in my water?

Let tap water run for 30 seconds to 2 minutes before using it for drinking or cooking, use cold water only (hot water dissolves lead), and consider a certified lead-reduction filter. For health concerns, contact your pediatrician or the CDC.
