Lead service lines in Topsham, ME

Most homes in Topsham get water from the Brunswick/Topsham Water District, which serves about 18,863 people in the area. The town is also served by six smaller water systems that provide water to schools, businesses, and mobile home parks.

What we know about lead service lines in Topsham

Lead service lines are pipes that connect homes to the public water main. If your home was built before 1986, there's a higher chance your service line contains lead—especially in New England, where they were common.

The Maine Department of Environmental Protection requires water utilities to maintain inventories of known lead service lines. For Topsham's largest utility (Brunswick/Topsham Water District), that inventory data has not yet been made fully public. The smaller utilities serving Topsham also have not disclosed their lead service line counts in publicly available records.

This does not mean there are no lead service lines in Topsham. It means the data hasn't been published yet. The federal Lead and Copper Rule requires all water systems to complete their service line inventories by October 2024.

Why this matters

Lead can leach into drinking water as it passes through old pipes. At high levels, lead exposure poses serious health risks, especially for young children and pregnant people. Even low levels of exposure can affect learning and development.

The good news: lead in water is preventable. A simple water test, a point-of-use filter, or replacing the service line can eliminate the risk.

Next steps for residents

  • Contact your water utility to ask about your service line material. Call the Brunswick/Topsham Water District at their customer service line, or visit their website.
  • Test your water if your home was built before 1986 or if you're concerned. Maine's Department of Environmental Protection can direct you to certified labs.
  • Use a filter while you investigate. NSF-certified filters reduce lead in drinking water. Look for one certified for lead removal (typically under the sink or pitcher-style).
  • Check if your service line qualifies for replacement funding. Some Maine programs offer cost assistance.

Common questions

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

Contact your water utility and ask them to check their service line inventory records. If you can't reach them, you can also look at your water meter (usually in the basement) and check if the pipe is lead-colored (dull gray) and soft enough to scratch with a coin. Your utility can also arrange for a professional inspection.

Is lead in Topsham water a major problem?

Most homes in Topsham are served by the Brunswick/Topsham Water District, but detailed lead service line data for this utility hasn't been publicly released yet. To know if it affects you, contact your utility or test your water if your home is older.

What should I do if my water test shows lead?

First, use a NSF-certified filter or boil your water (though boiling does not remove lead). Then contact your water utility and ask about replacing your service line—you may qualify for financial assistance through Maine programs. Consult your pediatrician if children in your home are affected.

How much does it cost to replace a lead service line in Maine?

Replacement typically costs $2,000–$5,000 depending on soil conditions and depth. Some Maine utilities and state programs offer cost-sharing or rebates. Ask your water utility about available programs before paying out of pocket.
