Lead lines in Johnstown
The most recent 90th-percentile lead result EPA lists for this system is 5 parts per billion (2025-06 to 2025-09). 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.

Free when scheduled. Greater Johnstown Water Authority says homeowners will not pay for lead service line replacement; the authority is covering the cost of its roughly $21 million effort, starting with its own reserves.

How much does it cost to replace a lead service line in Johnstown?
If you qualify for Johnstown's program, the private side costs you nothing. 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. That's what you'd pay if you replace it on your own or don't qualify.
How do I know if my home has a lead service line?
Look up your address on Greater Johnstown WA Riverside'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 Greater Johnstown WA Riverside 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.
