Lead service line replacement in Philadelphia

Updated · Editorial team; not yet technically reviewed

Short answer

In Philadelphia the water service line from the main to the meter belongs to the property owner. The Water Department replaces lead and galvanized lines free during planned water main projects, is running a federally funded free replacement pilot in selected ZIP codes, and offers 0% HELP loans payable over 60 months for owners who replace a lead line themselves.

What's different in Philadelphia

  • In Philadelphia, water service lines, from the main in the street to the meter, are the property owner's responsibility. [1]

  • PWD replaces known or discovered lead and galvanized service lines free of charge during planned water main projects, which reach roughly 1% of the city's mains each year; residents are notified by letter months ahead. [2]

  • PWD's federally funded Service Line Replacement Pilot replaces lead or galvanized lines free for eligible properties, starting in North and West Philadelphia: Phase 1 covers ZIP codes 19133, 19134 and 19140 (starting August 2026), and Phase 2 covers 19104, 19131, 19139, 19142, 19143, 19151 and 19153 (late 2026). [2]

  • Owners of residential properties with up to four units may qualify for a HELP loan at 0% interest, payable over 60 months, to replace a lead service line, if the water bill and meter are in order. [1]

Rowhouses and older blocks

Most Philadelphia homes are rowhouses on blocks built long before lead pipe was banned, so a single block can have many lead or galvanized lines and tight access through front basements. That's why PWD replaces lines block by block during main work and targeted the pilot at ZIP codes with high concentrations. For leaks and replacement methods anywhere, see water line repair.

Common questions

Who owns the water service line in Philadelphia?

The property owner owns the line from the water main in the street to the meter, so replacing it is the owner's responsibility unless a PWD program covers it.

Will PWD replace my lead line for free?

Yes, if PWD is replacing the water main on your block, or if your property is eligible for the federally funded pilot in selected ZIP codes.

Which Philadelphia ZIP codes are in the free lead line pilot?

Phase 1 covers 19133, 19134 and 19140; Phase 2 covers 19104, 19131, 19139, 19142, 19143, 19151 and 19153.

What is a HELP loan for lead service lines?

PWD's Homeowner's Emergency Loan Program offers a 0% interest loan, repaid over 60 months, to replace a lead service line at eligible properties of up to four units.

How do I apply for a HELP loan in Philadelphia?

Pre-apply at water.phila.gov/HELP or call (215) 685-4901.

How will I know if PWD is replacing my water main?

PWD notifies residents by letter several months before main work starts and offers to replace any lead or galvanized line then.

Does PWD replace galvanized service lines too?

Yes. During main projects and in the pilot, lead and galvanized metal lines are both replaced free.

What if my Philadelphia service line is leaking?

A leaking service line is the owner's to fix. Call a licensed plumber, and ask about a HELP loan if the line is lead.

What can Philadelphia tenants do about a lead service line?

The owner must authorize and, outside free programs, pay for the work. Tenants should ask their landlord and can use a certified lead filter meanwhile.

Why does PWD only reach about 1% of mains a year?

Main replacement is a long-term capital program, so free replacement through main work alone would take decades; the pilot and HELP loans are meant to speed things up.
