HARRIS COUNTY MUD 165 Lead Service Line Inventory
About this water system
HARRIS COUNTY MUD 165 serves approximately 40,503 people in Texas and sources water from surface water sources. This page summarizes what is publicly known about lead service lines in this system.
What is a lead service line?
A lead service line is the underground pipe that connects your home's water line to the main water line in the street. If your home was built before the 1980s, or if your system still uses older pipes, your service line might contain lead. When water sits in these pipes, small amounts of lead can dissolve into your water.
Lead is a serious health concern, especially for children under 6 and pregnant people. Even low levels of lead exposure can affect brain development and learning.
What we know about Harris County MUD 165
As of now, this water system has not yet completed a full lead service line inventory—the count of how many lead, non-lead, galvanized, and unknown lines serve the district.
The Safe Drinking Water Act requires all water systems to create and publicly share these inventories. Most Texas systems are working toward completion, with deadlines set by the state and EPA.
What you can do right now
Contact your water utility directly. They can tell you:
- Whether your specific address has a lead service line
- What water testing they recommend
- Whether they have a replacement program
Test your water. Even if your service line is not lead, lead can still enter your home from internal plumbing or fixtures. A simple test costs $15–30 and tells you if lead is present.
Use a filter. NSF-certified filters (marked "NSF 53" or "NSF 58") remove lead from drinking and cooking water while you wait for testing or replacement.

Frequently asked
Is there lead in Harris County MUD 165 water?
The system has not yet completed a full inventory of lead service lines, so the extent of lead risk is unknown. Contact the utility or test your water to know your home's status.
How do I know if I have a lead service line?
Your water utility can tell you based on your address and their records. Older homes (pre-1980s) are more likely to have lead lines. A plumber can also inspect the line where it enters your home.
Is it safe to drink the water now?
Lead service lines don't always mean lead in your tap water—it depends on water chemistry and internal pipes. Testing is the only way to know for sure. Call your utility or a lab to arrange a test.
What should I do if my water has lead?
Use an NSF-certified filter for drinking and cooking water, flush your taps before use, and contact your utility about replacement programs or financial help.
