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

Costs typically range from $3,000 to $10,000+ depending on line length, soil conditions, and local labor rates. Your water utility or a licensed plumber can provide an accurate estimate for your property.

Does New Jersey require water utilities to replace lead pipes for free?

No, but some utilities offer rebates, grants, or cost-sharing programs. Federal and state loans are available at low interest rates. Contact your utility directly to learn what assistance they provide.

What is the Drinking Water State Revolving Fund and how do I apply?

It's a state program offering low-interest loans for water infrastructure improvements, including lead line replacement. Contact the New Jersey Department of Environmental Protection's Division of Water Quality for loan terms and application details.

How do I know if my service line is made of lead?

Your water utility can tell you based on their service line inventory, or a plumber can inspect your line. You can also request a free or low-cost water test from your utility to check for lead levels.

Lead Pipe Replacement Grants and Funding in New Jersey

New Jersey is home to approximately 3,421 water systems serving 9.5 million people. As of the latest inventory data, 147,135 lead service lines have been identified across the state. If you own a home with a lead service line, several funding programs may help cover replacement costs.

State and Federal Funding Sources

Drinking Water State Revolving Fund (DWSRF)

New Jersey's DWSRF program offers low-interest loans to water systems and eligible homeowners for lead service line replacement. The program prioritizes projects in disadvantaged communities—those with median household income at or below 200% of the state median. A portion of DWSRF funding is set aside specifically for these communities to ensure equitable access.

Contact the New Jersey Department of Environmental Protection (NJDEP) Division of Water Quality for current loan terms, interest rates, and eligibility details. Loans typically carry below-market rates and flexible repayment periods.

Bipartisan Infrastructure Law (BIL) Funding

While federal infrastructure funding has supported water system improvements nationwide, New Jersey's specific allocation and distribution timeline should be confirmed directly with NJDEP. Infrastructure funding often flows through water systems rather than directly to homeowners, so ask your utility whether they have received BIL grants for lead replacement programs.

Local and Utility-Specific Programs

Some New Jersey water utilities have established their own assistance programs for lead service line replacement. These may include rebates, cost-sharing arrangements, or direct replacement services. Availability and terms vary significantly by utility.

Check with your local water utility to ask:

Do they have a lead service line replacement program?
Are rebates or grants available to homeowners?
Can the utility recommend contractors or manage replacement?
Do they offer payment plans or cost-sharing?

Income-Based Assistance

New Jersey residents with low to moderate incomes may qualify for additional assistance through state or federal programs. Your water utility can direct you to available resources or you can contact NJDEP directly.
