Lead Service Lines in Dover, NH

Dover serves about 29,740 residents through 9 water systems. The largest is Dover Water Department, which supplies roughly 29,000 people.

What we know about lead pipes in Dover

Currently, there are no confirmed lead service lines reported in Dover's water systems, and no galvanized pipes flagged as a concern. However, this doesn't mean lead pipes don't exist—it means they haven't been inventoried or reported yet.

Most of Dover was built in the 1800s and early 1900s, decades when lead pipes were common in New England water systems. Lead service lines are the pipes that connect the water main under the street to homes. If your house was built before 1980, there's a real possibility your service line contains lead, even if it hasn't been officially documented.

Why this matters

Lead can leach into drinking water, especially if water is acidic or if pipes are disturbed. For children and pregnant people, even small amounts of lead exposure can affect development. If you're concerned about your health or your family's exposure, talk to your doctor or contact the CDC.

How to find out if you have a lead service line

Contact Dover Water Department directly. They can tell you whether your home's service line has been tested or inspected. Many water systems in New Hampshire are beginning lead inventories as part of federal drinking water requirements.

You can also:

  • Ask for a copy of your service line inspection record
  • Request a free or low-cost water test if available
  • Check if your utility has a public inventory map online

Protecting your water in the meantime

While you're waiting for answers, run cold water for 30 seconds before drinking or cooking if your tap hasn't been used for several hours. This flushes stagnant water from pipes. If you're pregnant or have young children at home, consider using a certified lead-reducing filter until you know more about your service line.

Next steps for residents

  • Contact Dover Water Department at their main line to ask about your service line status
  • Request a water quality test if you haven't had one recently
  • If your home was built before 1980, ask whether a lead service line inspection has been done
  • Check the utility's website for any published lead inventory or testing results

Common questions

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

Contact Dover Water Department directly—they can check their records for your address. You can also look at the water pipe visible where it enters your home, though lead pipes can look similar to other metals. If your home was built before 1980, it's worth asking for an inspection.

Is Dover's water safe to drink?

Dover Water Department tests and treats water to meet EPA safety standards. However, if lead service lines exist in your home's connection, lead can leach into your water. Test your tap water if you're concerned, and contact your utility for a free or low-cost test kit.

What should I do if I'm worried about lead exposure?

Talk to your doctor, especially if you have young children or are pregnant. The CDC website has guidance on lead health risks. In the short term, run cold water for 30 seconds before drinking if your tap hasn't been used for a few hours.

Will Dover water systems be required to replace lead pipes?

Under federal law, water systems must inventory and eventually replace lead service lines, but timelines vary. Contact Dover Water Department to ask about their replacement program and whether your address is scheduled.
