Lead Service Lines in Nashville, TN

Nashville's water systems serve approximately 849,685 people across 8 utilities. The largest is Metro Water Services, which supplies 778,153 residents.

What we know about lead service lines in Nashville

Lead service lines are the pipes that connect the main water line under the street to your home. If your home was built before the 1980s, there's a higher chance your service line contains lead.

Currently, none of Nashville's water systems have reported confirmed lead service lines in their inventories. However, this does not mean lead service lines don't exist in Nashville—it means utilities either haven't completed their surveys yet or haven't found them. The absence of reported lead is different from the absence of lead.

Why this matters

Lead can leach into drinking water, especially if water sits in pipes overnight or if pipes are corroded. Children under 6 are most vulnerable to lead exposure. Even low levels can affect development.

If you're concerned about lead in your home's water, the first step is contacting your water utility to ask about your service line. They may have records of when your home was connected, or they can advise you on testing options.

Your water utility

Metro Water Services (serving most of Nashville) manages the city's main water distribution. You can reach them to:

  • Ask if your address has a lead service line
  • Request a water quality test
  • Learn about free or low-cost testing programs
  • Find out about replacement programs or financial assistance

Smaller systems serving Nashville residents include Harpeth Valley U.D. and several smaller utilities. Contact your local provider directly if you're unsure which system serves your address.

Testing your water

If you suspect lead in your water, home test kits are available at hardware stores, though they vary in reliability. Your water utility or county health department can recommend certified testing labs. Some utilities offer free or subsidized testing—ask when you call.

Next steps for residents

  • Contact your water utility to ask about your service line and request any available records
  • If concerned, request a professional water test through your utility or local health department
  • If lead is found, utilities sometimes offer replacement programs—ask about eligibility and funding
  • For health questions, consult your pediatrician or the CDC's lead information page

Common questions

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

Contact your water utility (usually Metro Water Services in Nashville) with your address—they may have records of your service line material. Alternatively, you can hire a plumber to inspect the line where it enters your home, or request a water quality test to check for lead.

Is Nashville water safe to drink?

Nashville's water systems test regularly and report results publicly. However, lead can enter water through service lines and household plumbing. If you have an older home or are concerned about lead, contact your utility for testing options.

Can I get my lead service line replaced for free in Nashville?

Some water utilities offer replacement programs or financial assistance, but availability varies. Contact Metro Water Services or your local utility directly to ask about programs in your area and whether you qualify.

What should I do if my water test shows lead?

First, contact your water utility to report the result and ask about next steps. Run your tap water for 30 seconds before drinking to flush out stagnant water. For health concerns, especially if you have young children, consult your pediatrician or the CDC.
