Lead water pipe replacement in Kildeer
Anticipated $0 direct cost to the homeowner — Aqua Illinois's draft 2025 LSLR plan for the Hawthorn Woods water system (which serves parts of Kildeer, including Kildeer Estates and Wentworth of Kildeer) states it "anticipates" replacing the customer-owned side at "no direct cost to Hawthorn Woods customers," recovered through water rates. This is a stated goal, not a guarantee: it requires Illinois Commerce Commission (ICC) approval to use water rates for customer-side work, and the plan says it will offer full replacement at no direct cost only "when financially feasible," depending on final program costs and available grants. Utilities are not legally required to pay for the customer-owned side, and homeowners must sign a license agreement to participate; if the no-cost goal is not realized, the homeowner's cost is not published.
Kildeer's program at a glance
Who supplies the water
Kildeer has no municipal water utility and the Village of Kildeer website publishes nothing about water supply or lead service lines. Most public-water customers in the Kildeer area are served by the private utility Aqua Illinois via its Hawthorn Woods system (IL0975040, two deep wells in the Galesville Aquifer); the system's official LSLR plan lists served areas including 'Kildeer Estates, Wentworth of Kildeer, Glenshire, Stone Bridge, Forest Lake.' A small section of Kildeer is reported to receive water from the Village of Lake Zurich's well system (IL0970850), and other homes are on private wells.
Program
Aqua Illinois-Hawthorn Woods Lead Service Line Replacement (LSLR) Plan (draft, April 2025, per Public Act 102-0613); not named as a branded village program — Kildeer itself has none
What the homeowner pays
Anticipated $0 direct cost to the homeowner ("no direct cost to Hawthorn Woods customers") per Aqua Illinois's draft 2025 LSLR plan — contingent on ICC approval to recover customer-side costs through water rates AND on financial feasibility (the plan offers full replacement at no direct cost only "when financially feasible," depending on final program costs and available grants); participation requires signing a license agreement granting Aqua access. If the no-cost goal is not realized, the homeowner's cost is not published.
How to check your line
Aqua Illinois publishes downloadable service-line material inventory PDFs per district on its Lead Service Line Materials Inventory page (item "Aqua Illinois-Hawthorn Woods IL0975040" covers the Kildeer-area subdivisions). The plan also says Aqua's website explains how customers can self-identify their service line material. No interactive address-lookup portal is published.
How to get into the program
Not published. No application form or sign-up process appears on official pages; replacements are utility-scheduled ("during infrastructure work, including water main replacements and leak and break repairs, and through prioritized replacements"). Aqua Illinois customer line: 877.987.2782.
Worth knowing
The Hawthorn Woods system inventory (as of March 24, 2025) shows ZERO known lead or galvanized-requiring-replacement lines on either the Aqua-owned or customer-owned side; 58 Aqua-side and 54 customer-side services are "unknown," and staff estimate 0-5% of unknowns (0-3 lines total) could be lead. Total anticipated program cost is only $0-$45,000 (avg full replacement ~$15,000/line). Statewide, Aqua Illinois plans to replace all identified lead and galvanized lines over 10 years beginning 2027; the Hawthorn Woods final plan/inventory is due to IEPA by April 15, 2027, with 7% annual replacement thereafter. Practical takeaway per official sources: lead service lines are essentially a non-issue in Kildeer's Aqua-served areas. For the small Lake Zurich-served section, Lake Zurich maintains an IEPA material inventory (dated 5/12/2025) on lakezurich.org and has bid a 2026-2027 Lead Service Line Replacement Project; its detailed cost policy was not fetched. Homes on private wells are outside any LSLR program. The Village of Kildeer itself publishes no lead service line information.

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 Kildeer, 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 Kildeer before making decisions based on them.

- How do I find out if my Kildeer home has a lead water line?
-
Aqua Illinois publishes downloadable service-line material inventory PDFs per district on its Lead Service Line Materials Inventory page (item "Aqua Illinois-Hawthorn Woods IL0975040" covers the Kildeer-area subdivisions). The plan also says Aqua's website explains how customers can self-identify their service line material. No interactive address-lookup portal is published.
- 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.
