Cascade discusses lead-service line replacement plan after DNR inventory
Summary
Council discussed a Department of Natural Resources mandate to inventory and replace lead service lines, identified about 38 likely lines in Cascade, and debated funding options including fronting costs from the water fund and assessing homeowners.
Cascade City Council discussed steps to address lead service lines on April 14 after the Iowa Department of Natural Resources required a service-line inventory and replacement plan.
Marty, a city public-works staff member, told council members that the inventory identified about "38" service lines that may be lead or galvanized and therefore flagged under the DNR rules. "About 38," Marty said when asked how many lines were identified. Marty and other staff described how the DNR treats galvanized service connections as an automatic flag for lead unless verified otherwise and that the DNR has provided up to 10 years to complete replacement work.
Council and staff discussed funding and logistics. Staff and councilors said federal or state funding may be available through the State Revolving Fund (SRF), but that SRF requirements (including domestic-product rules) can make the program impractical for some local projects. City staff proposed sending notices to affected property owners, collecting responses, and budgeting money in the water fund to pay contractors up front and then assess costs back to homeowners over time.
Council members asked for cost and scheduling details. Staff estimated replacement costs would vary by length and conditions and gave a broad range: "it could be, you know, what, dollars 1,200 all the way to $5,000 or whatever," reflecting excavation depth and complexity. Main Street replacements were identified as the most complex and likely the most expensive, and the city noted there were roughly four flagged properties on Main Street.
Staff noted that in some cases the city may be able to bundle multiple replacements under one contract to achieve lower unit costs. Council discussed giving property owners time to plan and save, with suggestions such as a multi-year notice and a three-year window to develop a replacement plan before the city would take stronger action. Staff reiterated the legal division: the city owns the water main, while the homeowner is responsible for the pipe from the main to the house, though the DNR expects municipalities to ensure compliance with the long-term replacement schedule.
No formal resolution was adopted on April 14; council asked staff to prepare outreach and budget options for future action.
