City projects funded by state loans
Hammond Water Works is replacing hundreds of known lead service lines in group contracts funded by a $5 million Indiana State Revolving Fund award from 2025. The city has not published homeowner cost terms online, so ask whether your street is in a current group and whether the private side is covered.
How to get it
- Call Hammond Water Works and ask whether your address is in a current replacement group.
- Ask in writing whether the private side is covered at no cost.
- Keep any letter the utility sends; it explains access and consent.

Lead lines in Hammond
The most recent 90th-percentile lead result EPA lists for this system is 3 parts per billion (2025-01 to 2025-12). 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 Hammond compares: it ranks #15 of 7,556 U.S. water systems and #3 of 232 in Indiana for lead and galvanized lines. 82.0% of its service lines need replacing, compared with 11.7% across Indiana. See the national ranking.

Who pays in Indiana?
Indiana law lets utilities include the cost of replacing customer-owned lead service lines in rates, with approval from the Indiana Utility Regulatory Commission. Citizens Energy in Indianapolis uses this to replace private lines with no extra charge beyond a monthly fee. Other Indiana cities rely on State Revolving Fund money and set their own terms.
The law: Ind. Code 8-1-31-6.6. Mandatory? No owner mandate; the federal rule requires replacement by 2037. Funding: Indiana Finance Authority State Revolving Fund.

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.

Common questions
Is lead service line replacement free in Hammond?

Is lead service line replacement mandatory in Hammond?
No owner mandate; the federal rule requires replacement by 2037.
How much does it cost to replace a lead service line in Hammond?
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 Hammond Water Works 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 Hammond Water Works 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.
