Water Service Line Cost in 2026: Per Foot, Plus What Utilities Charge

A new water service line costs about $30 to $150 per foot installed, with $50 per foot as a typical planning figure (national estimate). A house 70 feet behind its meter therefore needs roughly $2,100 to $10,500 of private pipe. The street side, from the main to the meter or property line, is usually built or priced by the utility. Published 2026 charges for that segment run from $1,177 at the Las Vegas Valley Water District to $8,464–$9,701 for a 1-inch service in Portland. Who pays for which segment depends on where the utility draws its line.

Two segments, two owners

A water service has two parts, and in most cities they are built, paid for and later repaired by different parties.

• Public side: main to meter, curb stop or property line. This segment runs under the street or right-of-way. Utilities either build it themselves for a published charge or require a licensed contractor to build it under a permit and inspection.
• Private side: meter to house. Your plumber installs this under a building-department plumbing permit, and you pay the market rate. After construction it is normally the owner’s to maintain.

Where the handoff sits varies. In the utilities we checked:

• El Paso Water’s $4,380 connection charge covers tapping the main, the line to behind the curb, and the meter box (Rules and Regulations No. 7, July 8, 2026).
• Phoenix city crews install the tap from the main to the property line under its Full Water Service Fee (City of Phoenix; the page lists a 2008 effective date, so confirm the amount).
• Sacramento installs the tap, corporation stop, pipe to the point of service and meter box, while your contractor excavates and restores the pavement (Department of Utilities, July 2026).
• Atlanta’s Department of Watershed Management installs only in the right-of-way. The owner connects the private line (DWM meter purchases).
• SAWS normally does not install service lines. A private contractor builds them under a water connection permit, and SAWS publishes only time-and-materials estimates for when it does the work.
• OUC offers both options: it builds the connection, service line, curb stop, meter and box for $4,155 (5/8-inch), or sets only the meter and box for $460 when your contractor builds the rest.

If a leak shows up later, the same handoff usually decides who fixes it. Ask the utility for its service-line ownership rule in writing when you apply.

What utilities charge for the street side

Published utility charges to install a new residential water service on the public side. Some include the meter (noted). Capacity fees are excluded; see water connection cost. Rows marked “confirm” rely on schedules older than FY2024. Checked 2026-09-24.

Most of these are flat prices. Your cost for this segment is the same whether the main is 15 feet or 45 feet away, except where the utility splits same-side and far-side taps (SAWS, Fort Worth) or street type (Seattle). The OUC tariff lets you measure what the utility’s work is worth in one city: $4,155 − $460 = $3,695 is the price of the connection, line and curb stop that your own contractor would otherwise build.

Private side: what the per-foot numbers mean

Our per-foot figures are national estimates for an installed line, meaning trench, pipe, bedding, backfill and connection (benchmark method):

• Low, about $30/ft: the lowest state-average replacement cost in a national homeowner data set, spread over about 50 feet.
• Typical, about $50/ft: a 2024 NRDC and Safe Water Engineering estimate built from RSMeans unit costs, $2,096 for 40 feet of open trench in grass.
• High, about $150/ft: the same study’s medium scenario, $10,703 for 71 feet of copper under a street.

Pipe material is a small part of it. In the same data, installed polyethylene runs about $5.40 per foot and copper about $23.41. What moves the price is digging: surface type, depth, rock, and whether the line crosses pavement.

Private service line cost by length at the national low, typical and high rates (national estimate).

On long rural runs the upper rates overstate cost when the trench is in open soil and shared with other utilities. Price the trench separately with the trenching cost guide, which puts normal-soil trenching at $4 to $15 per foot (national estimate), and add pipe and fittings. For a street crossing done by bore or open cut, our national estimate is $1,000 to $10,000 per crossing, typical $4,000.

Worked examples

Tucson: main on the far side of a paved street

• Tucson Water new 5/8-inch service and meter, with pavement replacement: $2,700
• CAP water resource fee, 5/8-inch: $240
• Private line, 60 ft × $50/ft (national estimate): $3,000

Total: $2,700 + $240 + $3,000 = $5,940. At the national low and high rates the private line is $1,800 to $9,000, so the total ranges from $4,740 to $11,940. Add the plumbing permit (national estimate $100 to $1,300) and sewer. The Tucson page covers Pima County’s sewer connection fee.

San Antonio: contractor-built service

SAWS normally expects your contractor to build the public side. Its own estimate for a 3/4-inch service is $1,400 on the same side of the street and $2,100 on the far side. That makes a sensible check on contractor bids, not a price you can order. Add a 90-foot private line at $50 per foot ($4,500) and the far-side case comes to $2,100 + $4,500 = $6,600 before impact fees, which start at $5,470 for a 5/8-inch meter in the low elevation zone.

Ways the street side gets more expensive, or cheaper

• Wide streets and bores. Raleigh Water will not tap across divided roads or streets 45 feet or wider. El Paso Water lists $15,000 or more for a right-of-way bore.
• New pavement. Fort Worth bars taps in pavement less than two years old, which can force a longer route or a delay.
• Arterial streets. Seattle charges $1,375 more on an arterial ($6,175 vs $4,800 for 3/4-inch).
• Building during main construction. Charlotte Water takes 10% off its 5/8-inch connection fee when the service goes in while the main is built, about $441 on $4,407. Portland charges $4,469 for a 1-inch service installed with a main extension, compared with $8,464 standalone. Seattle lists $1,500 discounts that may apply for common trenches, manifolds and contractor-supported installs.
• Developer-built services. On Charlotte lots where the developer installed the service under a donated-project contract, there is no connection fee. The lot pays the system development fee and a $208 meter charge.
