In November 2025, a plain city letter started showing up in South Haven mailboxes. It told each homeowner one of three things about the pipe running from the street into their house: known lead, galvanized, or still unknown. Some of the letters went to owners of newer homes, because even a house built well after lead pipe fell out of favor can still have an unverified segment where the old main connects to a newer line.
For most residents, the letter was a heads up about a city project. For anyone buying or selling in South Haven this year, it's something closer to a timing problem. The city is replacing these lines at no cost to homeowners, which removes what used to be an expensive repair argument during a home sale. What it hasn't removed is the wait. A property can sit in "unknown" status for months while crews work through other streets first, and that status doesn't resolve itself just because a closing date is approaching.
Three Words on an Otherwise Ordinary Letter
The South Haven Area Water-Sewer Authority, known locally as SHAWSA, supplies water to nearly 11,650 customers from a filtration plant that draws Lake Michigan water through an intake about a mile offshore. The Michigan Department of Environment, Great Lakes, and Energy says Michigan water systems must inventory their service lines; since 2024, the city and SHAWSA have worked through that inventory, sorting each one into known lead, galvanized, or unverified. Crews from the City of South Haven and a contractor called Five Star Energy Services have been going block by block ever since, confirming what's actually in the ground and replacing anything that qualifies.
The city's public messaging has been consistent on one point: this work happens at no cost to the homeowner. A February 2026 update from the city noted that hundreds of service connections had already been replaced or confirmed as non-lead, with more scheduled throughout the season. That's meaningfully different from how this kind of repair has traditionally worked in older housing stock, where a homeowner discovering a lead line typically faced the cost themselves.
Where the Money Came From
The funding traces back to a $9,158,291 Drinking Water State Revolving Fund award that the Michigan Department of Environment, Great Lakes, and Energy gave SHAWSA in September 2024, covering a new elevated storage tank, a booster station, water main replacement, and roughly 2,100 lead service line replacements. Part of that award, about $5.8 million, came through the federal Bipartisan Infrastructure Law, with the remainder structured as a low-interest state loan.
At the groundbreaking that October, officials framed the timeline plainly: SHAWSA expected to clear every lead service line from the distribution system within three years.
Three years from an October 2024 groundbreaking points toward completion sometime in 2027. That's the backdrop worth knowing if you're comparing two similar South Haven listings and one seller mentions the city already replaced their line while the other says the status is still pending. Neither is a red flag on its own. What matters is where each address sits in a multi-year rollout that's still in progress.
Why Free Doesn't Mean Fast
The city's own language calls this "verification and replacement," and both halves take time. A line has to be physically confirmed before it's scheduled for work, and confirmation depends partly on residents responding to inspection requests. The city has said customer participation is essential to finishing the project, which means an address can stay in unknown status simply because nobody has been home to let a crew check the connection.
South Haven also has other underground work running at the same time. Kalamazoo Street, from Blue Star Highway to Lovejoy Street, began a full reconstruction in August 2026 that includes new watermain and storm sewer work alongside the roadbed itself. None of that changes what the lead line program does, but it's a reminder that DPW crews are juggling more than one trench this year, and a service line verification on a street with other active work may take longer to schedule than one on a quiet block.
None of this should scare off a buyer or a seller. It should change how a timeline gets built.
The Gap Between the Disclosure Form and the Actual Pipe
The lead-based paint form covers paint, not what's buried under the yard. The service line is a separate issue entirely, governed by a state rule that required every Michigan water system to inventory its lines by October 2024 and replace lead or galvanized ones over a 20-year window.
Michigan's Seller Disclosure Act asks sellers to report known defects, but it doesn't require them to inspect areas that are generally inaccessible, and a buried water line qualifies. A seller who has never received a city letter, or who received one showing "unknown," isn't concealing anything by leaving that box blank. The honest answer is that they don't know either. That's exactly why checking the status independently matters more than reading the disclosure form closely.
| Letter status | What it means | Before you close |
|---|---|---|
| Known lead | Line identified, scheduled for free replacement | Confirm the scheduled date and whether it falls before or after your target closing |
| Galvanized | Line identified as galvanized, also eligible for replacement | Same as above, ask for a written timeline from DPW |
| Unknown | Not yet verified, often because the resident hasn't scheduled an inspection | Request verification now rather than waiting for the city to reach that block |
Checking Before You Write or Accept an Offer
- Look up the address on SHAWSA's interactive verification map before writing an offer, not after.
- If the status shows unknown, call the South Haven Department of Public Works and ask for Dustin Guminski, who has been the city's point of contact on this project.
- If the status shows lead or galvanized, ask whether replacement is already scheduled or completed, and get that timeline in writing.
- Build a buffer into your closing timeline if verification is still pending, especially if the address is on a street with other infrastructure work underway.
- If you're preparing to list, request verification before you go active. A confirmed status, in either direction, is one less open question during a buyer's due diligence period.
For sellers specifically, the calculus has flipped from a few years ago. A lead line found on an older South Haven property used to be a negotiating point, something a buyer's inspector flagged and a seller offset with a credit. Now the replacement itself is the city's project, funded and scheduled independently of the sale. The negotiation isn't about who pays for the pipe. It's about whether the verification and the closing date land in the right order.
A Few Direct Questions
Does the homeowner pay anything for the replacement? No. City communications have consistently described the verification and replacement work as being done at no cost to the homeowner.
Is this the same as the lead-based paint disclosure on my purchase agreement? No. The federal lead-based paint form covers painted surfaces in homes built before 1978. The service line program is a separate, state-mandated infrastructure project covering the underground pipe between the water main and the house.
What if my address doesn't show a result on the map at all? Call the South Haven Department of Public Works directly and ask for Dustin Guminski. An address without a listed status usually means it hasn't been reached yet in the verification sequence.
Does an unknown status mean the line is lead? No. Unknown simply means the material hasn't been confirmed. Many addresses checked so far have come back non-lead.
If you're weighing a listing or working through an offer in South Haven this fall, checking an address against SHAWSA's map takes a few minutes and can save weeks later in the transaction. Amy O'Sullivan works this kind of detail into the timeline from the start, so a status letter never becomes the thing that stalls your closing.
