Water Line Replacement Cost

Published sewer line costs (2026)

MethodCost per footPublished job totalUse when
Traditional dig & replace$50–$250$7,500–$30,000Severe damage, wrong slope or bellies, or easy open access
Trenchless pipe bursting$150–$190$4,000–$20,000Pipe collapsed or badly deteriorated; full replacement needed
Trenchless pipe lining (CIPP)$135–$150$4,000–$20,000Pipe mostly intact with cracks, leaks or moderate roots

A published trenchless total for a 40–60 foot job is $4,000–$15,000. Sources survey different jobs, so their totals do not always match per-foot math. The calculator uses per-foot rates plus the add-ons you select.

The water line is the fresh-water pipe from the street or the meter to the house. It isn't the sewer lateral. People mix the two on quotes all the time. Sewer prices live on the sewer line replacement cost page. Use this page when the bill is for the pipe that brings drinking water in.

HomeGuide, on December 22, 2025, lists a main water line at $2,000–$5,000, about $3,500 in the middle. Angi, on October 14, 2026, centers lower: about $1,702, in a $646–$2,834 typical band.

A trench looks cheaper per foot. You still pay to put the yard or driveway back. Trenchless work, pulling or boring a new pipe through small pits, skips most of that restoration. The same choice shows up on sewer jobs; how trenchless sewer line replacement works is the picture for pits versus a long trench.

A water service line uses the same trench-versus-pits choice as a sewer lateral.

Trenchless water line replacement cost

HomeGuide lists trenchless water line replacement at $70–$250 per foot, against $50–$200 for a trench. On a 50-foot line, that's $3,500–$12,500 before permits. It usually wins when the line runs under a driveway or patio you'd otherwise have to replace.

PEX vs copper on a water service line

These are material prices only, before anyone is paid to install them.

MaterialPer foot, material onlyNote
PEX / polyethylene per foot$0.50–$5Flexible; HomeGuide groups polyethylene with PEX
Copper per foot$2–$10Holds up in freeze; can corrode in acidic soil
PVC per foot$0.50–$5Common where the code allows it

Indoor supply pipes are a different job. That bill is on house repiping cost.

Who owns the line

The city's water main is usually the utility's. The service line from the meter toward the house is usually yours. Confirm that in writing before you pay to open a street or a parking strip. The sewer version of that question is who is responsible for the sewer line.

Angi lists a water-line permit and inspection at $150–$500.

Some cities and water utilities run lead service line replacement programs that pay part or all of a lead service line. Ask the utility. This site doesn't publish a national rebate, because those programs are local.

Signs it is the water line, not the sewer

Low pressure at several faucets, a wet strip of yard that doesn't smell of sewage, a water bill that jumped with no extra use, or discolored tap water all point at the supply line. Several toilets backing up at once still point at the sewer.

A standard homeowners policy generally doesn't cover worn pipe. The sewer insurance page explains service-line endorsements; ask whether your form names the water service too.

Worked example

A 75-foot service line on a West Coast suburban lot. HomeGuide's trenched rate is $50–$200 per foot.

Pipe work is 75 × $50 = $3,750 on the low end, and 75 × $200 = $15,000 on the high end.

Trenchless at the same length is $5,250–$18,750. Add Angi's permit band, $150–$500. HomeGuide's published job total, $2,000–$5,000, is a shorter-line check. A 75-foot trench can overshoot that total. That is expected: the total mixes lengths.

If the leak is one short break and the rest of the pipe is sound, put HomeGuide's repair band, $400–$1,500, next to the full-line math before you sign.

How to save money

  • Before you approve a method, confirm which pipe it is: the water service or the sewer lateral.
  • Ask the water utility, in writing, where your ownership starts.
  • Get a trenched total and a trenchless total on the same footage.
  • If the pipe is lead, ask the utility about a replacement program before you pay the full bill.
  • Don't add the PEX or copper material price on top of an installed per-foot rate.

Common questions

How much does it cost to replace a water line from the street to the house?

HomeGuide (December 22, 2025) puts a main water line at $2,000–$5,000, with $3,500 as the average. Per foot, trenched replacement is $50–$200 and trenchless is $70–$250. Angi (October 14, 2026) centers lower, at about $1,702 and $50–$150 per foot. Length, depth, and a driveway over the pipe move the total.

Is a water line the same as a sewer line?

No. The water line brings drinking water in. The sewer lateral carries wastewater out. Mixing the two on a quote is how people buy the wrong job. Sewer replacement is priced on the sewer line replacement cost guide. Confirm with the water utility who owns the stretch from the meter to the house before you pay to dig in the street.

Does trenchless water line replacement cost more?

The trenchless per-foot rate is higher. HomeGuide lists $70–$250 against $50–$200 for a trench. A trench can still win on the invoice if the yard is open. Under a driveway, restoration after a trench is the extra line that often flips the total.

Who pays to replace a lead water service line?

The stretch from the meter to the house is usually the homeowner's. Some cities and water utilities run lead service line replacement programs that pay part or all of that work. Ask the utility in writing. This site doesn't publish a national rebate, because those programs are local.
