Lead Service Lines in Columbia, TN

Columbia's water comes from two public systems serving about 109,000 people. Both utilities—Columbia Power and Water Systems (serving roughly 85,000 residents) and Maury County Water System (serving about 24,500)—are required by federal law to maintain inventories of lead service lines in their networks.

What you need to know

Lead service lines are pipes that connect your home to the water main under the street. If your line is made of lead, water can pick up lead as it travels to your tap—especially if the water is corrosive or hasn't been sitting in the pipes for a while.

Neither utility has reported known lead service lines in their current public inventories, but inventories are still being completed across Tennessee. "Unknown" pipes—typically older galvanized steel or unidentified materials—may also pose a risk, since corrosion can release lead from the zinc coating.

The EPA and CDC recommend that families with young children, pregnant people, or breastfeeding mothers treat lead exposure as a potential health concern. If you're worried about your family's exposure, talk to your pediatrician or contact the CDC's lead hotline.

How to find out about your service line

Your water utility can tell you what material your service line is made of. Start by contacting your provider:

  • Columbia Power and Water Systems: Serves most of Columbia's city limits
  • Maury County Water System: Serves areas outside the city proper

Call or visit their website to request your service line material. Be ready to provide your address. If your utility hasn't finished its inventory, ask when that information will be available.

What to do if you have a lead service line

If you learn your line contains lead, the best long-term solution is replacement. This is a significant project—pipes run underground from the street to your home—so costs vary widely. Some utilities offer assistance programs or partial funding. Ask your water provider about available resources.

In the meantime, you can reduce exposure by running the tap for 30 seconds before using water for drinking or cooking (especially first thing in the morning), and by using cold water for drinking and cooking, since hot water dissolves lead more easily.

Next steps for residents

  • Contact your water utility to request your service line material
  • Ask when their lead service line inventory will be complete
  • If you have a lead line, inquire about replacement programs or financial assistance
  • For health concerns, speak with your doctor or call the CDC's hotline at 1-800-CDC-INFO

Common questions

How do I know if I have a lead service line in Columbia TN?

Contact Columbia Power and Water Systems or Maury County Water System—whichever serves your address—and request information about your service line material. They can look it up by your address or meter number.

Is lead in water dangerous?

Lead in drinking water is a health concern, especially for young children and pregnant people. For specific health guidance, contact your pediatrician or the CDC at 1-800-CDC-INFO.

Can I remove lead from my tap water myself?

Boiling water does not remove lead. A certified water filter (NSF/ANSI Standard 53) can reduce lead at the tap, but replacing the service line is the permanent solution.

What does it cost to replace a lead service line?

Replacement costs vary widely depending on length and difficulty. Ask your water utility about cost-sharing programs or low-interest loans—many utilities offer financial assistance for lead line replacement.
