Lead water pipe replacement in Deerfield

Lead pipes in Deerfield — common questions

Who pays for lead pipe replacement in Deerfield?

Voluntary residential cost-share (reimbursement) program per the Village's Lead Service Line Replacement Residential Cost Share Program packet (dated February 17, 2026) on deerfield.il.us: for full replacement of the entire lead service line (Village and private portions, water main into the building), the Village reimburses a 50% match up to a maximum of $6,000 per property, and this reimbursement also covers all exterior restoration (roadway, sidewalk, parkway). Where the public portion is known to be copper and only the private portion is lead, reimbursement is a 50% match up to $2,500. Galvanized piping is eligible only when located downstream of lead; only lead portions (plus such galvanized) are eligible. Funding is limited and awarded first-come, first-served; incomplete applications are rejected and forfeit their place in the queue. The program does NOT cover replacements done for repairs, system upgrades, or replacements required by Village ordinance (additions, new construction) or other regulatory agencies, and it is not retroactive — work performed before program approval is not reimbursable. One reimbursement per property; if other private work within 12 months of reimbursement would have required a service replacement anyway, the full reimbursement must be repaid (exception: change of ownership). Ownership context: the Village owns and maintains the portion from the water main up to and including the buffalo box (shutoff valve) or meter pit, typically in the parkway; the property owner owns the portion from the buffalo box into the building. Homeowner cost: the unreimbursed share of costs above the 50% match / cap ($6,000 full, $2,500 private-side-only), plus ineligible items such as interior finishes beyond drywall and basement flooring (e.g., cabinets, shelving), landscaping plantings, and extra costs from a service larger than 1.5-inch or non-metallic pipe. Reimbursement is calculated on a 1.5-inch Type K copper installation. Permit fees typically associated with a water service replacement are waived under the program (street/right-of-way deposits are held for 9 months after restoration acceptance, then released). Many restoration costs ARE reimbursable, including pavement/parkway/lawn restoration, drywall removal, basement flooring removal and replacement, and electrical grounding replacement. The homeowner obtains quotes and hires state-licensed, Village-registered plumbing/electrical contractors; if an outside meter pit exists it must be removed and the meter relocated inside. Reimbursement is paid after completed work, passed inspections, restoration acceptance, and Village approval of the signed Affidavit of Completed Replacement Work (typically mailed within 4-6 weeks). Program terms change — confirm current details with the municipality before planning around them.

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

Village-published Water Service Material Lookup (Community Portal property look-up via GIS Consortium) showing both public and private portions; Village also maintains an inventory based on installation age and building inspection records; self-check instructions (scratch test with key/screwdriver — bright silver indicates lead; magnet test distinguishes galvanized) on the Lead Service Line Information page.

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.
