Lead water pipe replacement in Northfield

Homeowner pays the full replacement cost up front (proof of payment required) and is reimbursed 50% of eligible costs based on the lowest of three licensed-plumber estimates, capped at $10,000 — i.e., the homeowner bears at least 50% plus anything over the cap and all ineligible costs (architectural/engineering/professional fees, interior repairs, driveways/private sidewalks, decorative plantings/hardscape, private electrical, temporary water facilities, deposits, any costs not in the original quote or exceeding the $10,000 max; the Village street/parkway opening bond is not waived, though Village permit fees are). Funding is limited — the Village budgets roughly 10 replacements per year, first-come, first-served, and only homes connected to a Village-maintained main and listed on the Village's Lead Service Line Inventory qualify; work must be completed within 90 days of permit issuance. In Village water-main projects/repairs, the Village replaces main-to-b-box and the homeowner is required to replace b-box-to-meter; if emergency repairs to a private lead line are needed, the homeowner must replace the entire line from main to meter within a Village-determined timeframe — homeowners in either situation get priority in the reimbursement program for that fiscal year, so they can still claim the 50%/$10,000 reimbursement.

Northfield's program at a glance

Who supplies the water

The Village of Northfield operates its own community water supply/distribution system but purchases its water from the Village of Winnetka, whose source is Lake Michigan surface water (per the Village's 2024 Annual Drinking Water Quality Report). The Village's own program applies to homes connected to a Village of Northfield maintained water main.

Program

Lead Service Line (LSL) Replacement Program (the cost-share component is called the Lead Service Line Replacement Reimbursement Program)

What the homeowner pays

Homeowner pays the full replacement cost up front and is reimbursed 50% of eligible costs (based on the lowest of three estimates), capped at $10,000 — i.e., the homeowner bears at least 50% plus anything over the cap and all ineligible costs (professional fees, interior repairs, driveways/private sidewalks, plantings/hardscape, temporary water facilities, deposits, costs exceeding the $10,000 max; the street/parkway opening bond is not waived). In Village water-main projects, the Village replaces main-to-b-box and the homeowner must pay to replace b-box-to-meter; if emergency repairs to a private lead line are needed, the homeowner must replace the entire line from main to meter within a Village-determined timeframe.

How to check your line

Consult the Village's Lead Service Line Inventory Map / "Properties with Lead Service" list (https://www.northfieldil.org/DocumentCenter/View/2804/, dated 12-30-24), linked from the LSL Replacement Program page; lead tap sampling data and inventory copies are available from Bill Wipperfurth, Public Works Department, (847) 441-3810.

How to get into the program

Submit the Lead Service Line Replacement Program Application (in the program document at https://www.northfieldil.org/DocumentCenter/View/2595/) with: three detailed written estimates from licensed plumbing contractors, a Contractor Checklist from the chosen contractor, completed plumbing permit applications, and three copies of construction plans. Work must be completed within 90 days of permit issuance and pass Village inspections; then submit a Reimbursement Request form with proof of payment. Questions: Building Department, (847) 784-3551.

Worth knowing

Program effective May 1, 2024; voluntary. Goal is replacing 12.5% of existing lead service lines per year over 8 years (~10 replacements/year budgeted) — the LSL Replacement Program page states all lead water services must be replaced by 2042. Funds are first-come, first-served with an annually set budget. Eligibility requires connection to a Village-maintained water main and listing on the Village's LSL Inventory; full main-to-home replacement (plus a new Village-specified AMI meter if needed) is required, and downstream galvanized lines connected to lead must also be fully replaced. Retroactive reimbursement is available for replacements done between January 1, 2023 and the program's effective date. Homeowners forced to replace due to Village main projects/repairs or emergency repairs get priority for that fiscal year. Homeowners who sign a risk-acceptance waiver instead of replacing are ineligible for reimbursement after the 8-year program window. No loan program is published. 2023 90th-percentile lead result was 3.4 ppb (no action-level exceedance at that time); a Village Drinking Water Notification (Jan 2026, per the Village site) reported that sampling of 35 lead-service-line homes found more than 10% exceeded 15 ppb.

The Illinois picture

Illinois' Lead Service Line Replacement and Notification Act requires every community water supply to inventory its service lines and replace lead ones on a state-mandated schedule. Two practical consequences for homeowners: your municipality can tell you what your line is made of, and full replacement — not partial — is the standard when work happens. Many suburbs coordinate replacements with water-main projects, which is often when the cost-sharing is most generous.

Where we come in

Remodels are where lead lines get discovered — kitchen and bath projects expose the plumbing, and permit inspections check service-line material against the municipal inventory. When that happens on a GS project in Northfield, we flag it early, point you at the program above before anyone spends your money, run the replacement through our Illinois-licensed plumbing and excavation partners, and restore everything the dig touched.

GS Construction & Remodeling is a licensed general contractor, not a municipal agency. Program details above summarize official municipal sources and change over time — confirm current terms with Northfield before making decisions based on them.

How do I find out if my Northfield home has a lead water line?

Consult the Village's Lead Service Line Inventory Map / "Properties with Lead Service" list (https://www.northfieldil.org/DocumentCenter/View/2804/, dated 12-30-24), linked from the LSL Replacement Program page; lead tap sampling data and inventory copies are available from Bill Wipperfurth, Public Works Department, (847) 441-3810.

Does GS Construction replace lead service lines?

Service-line replacement itself is licensed plumbing and excavation work — on GS projects it runs through our Illinois-licensed plumbing and excavation partners, and we handle what comes after: restoring the yard, landscaping edges, and any interior finishes the work touched. If a remodel uncovers a lead line, we flag it and point you at the municipal program before anyone spends your money.

Why do lead lines come up during remodels?

Kitchen and bathroom remodels expose the plumbing where it enters the home, and permit inspections increasingly check service-line material against the municipal inventory Illinois law requires. Finding out mid-project is normal — knowing your village's program before demo day is better.
