What's different in Boston

  • BWSC offers Boston property owners a free inspection and free replacement of their building's water service pipe if it is found to be lead. [1]

How to use the free program

  1. Check the Lead Service Map

    BWSC's map shows what the Commission has on record for your property's service line.

  2. Call the Lead Hotline

    Call (617) 989-7888 to request the free inspection.

  3. Inspection

    BWSC confirms the pipe material where the line enters the building.

  4. Free replacement if it's lead

    If the pipe is lead, BWSC replaces the private side at no cost to the property owner.

Triple-deckers and multi-unit buildings

Much of Boston's housing is older multi-family buildings, where one service line feeds several units. The program is for property owners, so tenants should ask their landlord to call BWSC. Replacing the line protects every unit at once. Interior lead solder and old fixtures are separate; a licensed plumber can check them. For leaks and replacement methods anywhere, see water line repair.

Why act while it's free

The program is funded by federal infrastructure money, and BWSC has said uptake has been slow. Replacing a lead line removes the largest single source of lead in a home's water, and doing it through BWSC avoids paying a private contractor for the private side.

What Boston homeowners usually check next

Common questions

Is lead pipe replacement really free in Boston?

Yes, for Boston property owners: BWSC provides a free inspection and, if the service pipe is lead, replaces it at no cost, using federal infrastructure funds.

How do I sign up for BWSC's lead replacement?

Call the BWSC Lead Hotline at (617) 989-7888.

How do I check if my Boston property has a lead line?

Use BWSC's Lead Service Map, or look at the pipe where it enters your basement: lead is dull gray and scratches to shiny silver.

Can tenants in Boston request a lead pipe replacement?

The program is for property owners, so ask your landlord to contact BWSC. One replacement protects every unit served by that line.

How many people have used Boston's free lead program?

About 400 property owners had used it roughly a year after it launched, which BWSC and researchers described as slow uptake.

Who pays for Boston's lead line program?

The federal Bipartisan Infrastructure Law funds the no-cost private-side replacements.

Does BWSC replace lead plumbing inside the building?

No. It replaces the water service pipe. Interior pipes, solder and fixtures need a licensed plumber; see repiping.

Will replacing my lead line disrupt my water?

Water is typically off for part of a day while crews connect the new line. Follow BWSC's flushing instructions afterward.

Should I filter my water before the replacement?

If you have a lead line, a filter certified to NSF/ANSI 53 for lead is a sensible precaution, especially after construction nearby.

Does the program cover Boston suburbs?

BWSC serves the City of Boston. Suburbs are served by their own water departments, so check with yours.
