How long does lead service line replacement take?

Updated November 2, 2026

The digging and pipe work usually takes one day, and your water is off for a few hours. The whole process, from sign-up to finished restoration, can take months because of scheduling and permits.

Typical timeline

1. Sign-up and inspection (weeks to months). You sign a consent form; the utility or contractor checks your line and marks utilities (811).
2. Replacement day (one day). Crews dig a pit at the street and one near your house, or a trench. With trenchless methods they pull the new copper or plastic line through. Water is off for a few hours, and someone usually needs to let crews into the basement.
3. Flushing (same day). Crews or you run the taps to clear debris and loosened lead particles. Follow the utility's flushing instructions exactly.
4. Restoration (days to weeks). Backfill, sod or seed, sidewalk and street patching. Interior patching may be on you.

After replacement

Lead levels can spike for a while after replacement because the work shakes loose particles in your plumbing. Federal rules require utilities to give you a pitcher filter and six months of cartridges. Use it for drinking and cooking, clean faucet aerators after a few days, and test your water a few months later.

How long until my street is scheduled?

That depends on your utility. Some aim to finish in a few years (Toledo, Racine, Rochester), others run to 2037 or later. Ask for your expected year and whether you can move up by self-reporting or joining a waiting list.
