Prospect Heights's program at a glance
Who supplies the water
Split system: the City of Prospect Heights operates a small municipal water system (~494 service connections per its inventory; earlier city studies cite ~1,080 connections serving ~2,700 people in the Rob Roy development, Camp McDonald Rd, Wheeling Rd, Casa Court, and Lake Claire areas) supplied with Lake Michigan water purchased through two connections with Illinois-American Water Company. The majority of properties in the city are NOT on city water — they use private wells, which the city does not regulate.
What the homeowner pays
not published (not applicable — zero lead service lines in the official inventory)
How to check your line
The city's official Water page (prospect-heights.il.us/121/Water) posts a downloadable "Water Service Line Inventory" spreadsheet (DocumentCenter/View/3822) listing every service address with PWS-side and customer-side material, plus a "Property Potable Water Source Map" (DocumentCenter/View/3825) showing which properties are on city water vs private wells.
How to get into the program

Worth knowing
The official Water page also shows Lead Tap Sample Data 2008-2023 with zero sites exceeding the 15 ppb action level, and links residents with lead concerns to Cook County DPH and Illinois EPA resources. Because the city's inventory shows no lead, galvanized-requiring-replacement, or unknown lines, no LSLR plan/waitlist/main-project coordination is published. Note: 229 of 495 inventoried lines are copper with lead solder (CLS), which counts as Non-Lead under the Act. Properties on private wells fall outside any community-water-system inventory; homeowners there are responsible for their own wells per the city site. Illinois-American Water is only the wholesale supplier to the city system, so its LSLR program does not apply to Prospect Heights city-water customers.

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 Prospect Heights, 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 Prospect Heights before making decisions based on them.

- How do I find out if my Prospect Heights home has a lead water line?

- 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.
