50% back, up to $5,000
Iowa City pays 50% of the cost of replacing a verified lead water service line, up to $5,000, on a first-come, first-served basis while its budget lasts. The program was funded with $500,000 in federal recovery money in 2023 and also covers 50% of service line insurance, up to $3,000.
How to get it

Lead lines in Iowa City
The most recent 90th-percentile lead result EPA lists for this system is 4 parts per billion (2021-01 to 2023-12). Under the new federal rule, the action level drops to 10 ppb in 2027. Galvanized lines count if they ever sat downstream of a lead pipe, because they can hold lead particles. Unknown lines must be identified by the utility, and many turn out to be lead.
How Iowa City compares: it ranks #173 of 7,556 U.S. water systems and #6 of 402 in Iowa for lead and galvanized lines. 10.0% of its service lines need replacing, compared with 7.7% across Iowa. See the national ranking.

Iowa City lead service line map: check your address
Every water utility had to publish an inventory of its service lines, and most offer an address lookup map. Start with Iowa City Water Department's official lead program page, which links to its lookup or explains how to get your line checked. The status will be lead, galvanized requiring replacement, non-lead or unknown. If it's unknown, you can usually check the pipe yourself and send the utility a photo.

Utilities must mail a notice every year to each home with a lead, galvanized or unknown line. See the federal timeline.
What would you pay?
Many utility loans are 0% (enter 0). Private loans run higher. Your real price depends on how far the house sits from the street, digging versus trenchless methods, permits and restoration. This is an estimate, not a quote.

Is lead service line replacement free in Iowa City?
Not fully free; it's a cost share (50% up to $5,000). Iowa City pays 50% of the cost of replacing a verified lead water service line, up to $5,000, on a first-come, first-served basis while its budget lasts.

How much does it cost to replace a lead service line in Iowa City?
Iowa City's program pays 50% up to $5,000. On a $7,500 job, that's $3,750 from the utility and $3,750 from you. Most private-side replacements cost about $4,000 to $10,000, and long or difficult lines can run higher. Price depends on the distance from the street to your house, whether the contractor digs a trench or pulls the new pipe through (trenchless), permits, and restoring your lawn, sidewalk or basement wall.
How do I know if my home has a lead service line?
Look up your address on Iowa City Water Department's service line inventory or check the letter it mailed you. You can also check the pipe where it enters your basement, usually near the meter: lead is dull gray, soft, and turns shiny silver when you scratch it with a key, and a magnet won't stick. Galvanized steel is gray too, but a magnet sticks to it. See our step-by-step guide.
What if I can't afford to replace my lead line?
Ask Iowa City Water Department about income-based help first; federal money often makes replacement free for low-income owners. Other options are utility payment plans, 0% city loans, state revolving fund programs, property tax assessments and home improvement loans. Our guide on paying for replacement lists them.
Who owns the water service line?
In most U.S. cities the utility owns the pipe from the water main to the curb stop or property line, and the property owner owns the rest, into the house. Some utilities, including Minneapolis and many in St. Louis County, treat the whole line as the owner's. Federal rules now require utilities to replace the whole lead line, not just their part.
