Water Connection Cost in 2026: Official Fees by City and What You’ll Pay

Connecting a new single-family home to city water costs $875 to $19,849 in utility charges across the 36 cities in our city table (median $3,108), before any private plumbing between the meter and the house. In the 15 cities of our first comparison below it runs roughly $1,700 to $16,000. The low end is a place like Columbus, where the capacity charge plus a 5/8-inch meter comes to $1,741 (Tucson is next at $1,980, with the service line and meter included). The high end is Sacramento, where a 1-inch service adds up to about $16,184 in FY2026-27 development, tap and meter fees. Most of the spread comes from one line item: the capacity or impact fee, which is a charge for buying into the water system, not for the pipe itself.

Below: published charges for a standard residential meter in 15 cities, what each total leaves out, and how to build your own estimate.

What a water connection bill is made of

Utilities split the cost of a new connection into three to six separate charges. Their names differ from place to place, and that makes it easy to miss one when you compare cities.

• Capacity, impact or system development charge. A one-time buy-in to treatment plants, storage and supply. It goes by many names: impact fee (Fort Worth, San Antonio), capital recovery fee (Austin), system development fee or charge (Charlotte, Denver Water, Seattle, Portland), capital facility fee (Raleigh), development charge (Colorado Springs Utilities), regional connection charge (Las Vegas). This is usually the largest item, and it usually scales with meter size.
• Tap or connection fee. The physical work of tapping the main, and in many cities also running the service line to the curb or property line and setting the meter box. See the water tap fee guide for how scope changes the price.
• Meter charge. The meter itself and its installation, sometimes bundled into the tap fee. Details by size are in the water meter installation cost guide.
• Permits, inspections and account fees. Usually $100 to $300 in total at the utility, plus the building department’s plumbing permit.
• Private service line. The pipe from the meter to the house, installed by your plumber and not billed by the utility. See water service line cost.

Sewer is a separate set of fees, often from a different agency. For that side, see sewer connection cost.

Official water connection totals in 15 cities

Utility charges for one new single-family water connection at the smallest standard residential meter each utility lists. Totals are our sums of the published line items shown; private plumbing, the building permit and sewer are excluded. Checked 2026-09-24.

*Austin’s meter, tap and inspection amounts come from the FY2026-27 fee sheet, which the utility marks as pending final adoption. Treat them as provisional. The $4,800 capital recovery fee is the published current rate.

Cost to connect to city water by city (2026)

Water-only utility charges for a typical new single-family home: tap or service connection, meter and water capacity or impact fee, at the smallest standard residential meter each utility lists. Sorted low to high; 36 cities, range $875 to $19,849, median $3,108. Each total is the sum of the line items on that city’s page; sewer, power, permits and the private service line are excluded.

What these totals include and leave out. Each figure is what the water utility itself publishes for the connection: the tap or service installation where the utility does it, the meter, and the capacity, system development or impact fee. Where a utility charges only a tap and meter and no impact fee, the total is small; where it charges a large impact fee, that fee is most of the total. Not included are the private service line from the meter to the house, trenching on your lot, the plumbing permit, account deposits and sewer charges. Some cities assume the developer already built the service line, so the total can be lower than the same utility would charge if it installed the line. For those costs, see what a 100-, 300- or 500-foot water line costs and the water meter installation cost guide.

Why one city costs several times another

Capacity fees follow growth costs, not pipe length

In Tucson the only capacity-type charge we found is the $240 CAP water resource fee. In Sacramento the FY2026-27 water development fee for a 1-inch meter is $10,953.50. Neither number depends on how far your house sits from the main. They reflect each utility’s plan for paying for new supply and treatment. That is why moving one town over can change your bill more than any site condition can.

Lot size and location formulas

Two utilities in the table price water by lot size. Denver Water adds $1.01 per square foot of lot (first 22,000 sq ft) to its $3,380 base for applications paid on or after July 1, 2026, so a 7,000 sq ft lot pays $3,380 + (7,000 × $1.01) = $10,450 before the meter. Outside the City and County of Denver the base is $4,740 plus $1.42 per sq ft. Colorado Springs Utilities tiers both its development charge and its water resource fee by lot size, which is why its range in the table runs from $9,829 to $19,586. Phoenix does the same thing by area rather than lot size: its 2025 water treatment impact fee is $4,387 everywhere, but the water transmission fee is $14,046 in the Northwest and similar growth areas and $0 in the Balance of City (City of Phoenix, effective June 23, 2025).

Who installs the service

Orlando shows the effect of scope inside one tariff. OUC charges $4,155 when it installs the connection, service line, curb stop, meter and box for a 5/8-inch service, and $460 when your contractor installs the connection and line and OUC only sets the meter (OUC Water Tariff, Jan. 1, 2026). The $3,695 difference does not disappear. It moves to your contractor’s bid.

Paving and street type

Cutting pavement costs more. Tucson Water’s 5/8-inch service is $1,740 unpaved and $2,700 with pavement replacement. Seattle’s 3/4-inch installation is $4,800 on a non-arterial street and $6,175 on an arterial. Portland’s 1-inch service is $8,464 without paving and $9,701 with it.

Worked example: building your own estimate

Take a new house in Charlotte on a lot with a water main in the street, a 5/8-inch meter, and the house set back 70 feet from the meter box.

• Charlotte Water connection fee (installs tap and service): $4,407
• Water system development fee: $1,453
• Private service line, meter to house, 70 ft × $50/ft (national estimate, typical): $3,500
• Plumbing permit (national estimate, typical): $300

Utility charges: $4,407 + $1,453 = $5,860. With the private line and permit: $5,860 + $3,500 + $300 = $9,660. Using the national low and high service-line rates of $30 and $150 per foot, the private line alone ranges from $2,100 to $10,500. For deeper setbacks, see what a 300- or 500-foot water line costs. The per-foot and permit figures are national estimates from our benchmark method, not Charlotte prices. Sewer adds Charlotte’s sewer fees; see the Charlotte tap fee page.

If you want this math done with your own footage and city, the calculator above, or the full utility connection cost calculator, combines local fee rows with per-foot estimates.

National estimates when your city is not listed

For a planning number before you have the utility’s schedule, our national estimates are:

• Water tap fee: $500 to $5,500, planning midpoint $1,600. This range comes from only five published utility schedules (n=5): the low end is a tap-only charge, the high end a utility-built service from the main to the property line.
• Meter set (5/8″ to 1″): $200 to $500, midpoint $300.
• Combined water and sewer impact fees: $3,500 to $25,000, midpoint $7,500. Many jurisdictions charge $0.
• Private service line: $30 to $150 per foot, midpoint $50.

These are national estimates built from published schedules and labeled secondary data; see how the benchmarks were built. A utility’s own schedule replaces them.

Timing traps that change the bill

• Plat date vs permit date. Austin picks the capital recovery fee table by the date the lot was platted: $4,800 per service unit for plats on or after October 1, 2023, $4,700 for 2018–2023 plats. Fort Worth’s rate follows the building permit date, and it rose on October 1, 2026 ($2,824 to $2,990 for a 5/8-inch meter).
• Scheduled increases. The Southern Nevada Water Authority regional connection charge adjusts every March 1. It was $7,358 before March 1, 2026 and is $7,998 now. Charleston Water System steps its impact fees every January 1 (3/4-inch water from $4,620 to $5,115 on January 1, 2027, per CWS). See why water and sewer tap fees are rising.
• Pending changes. Salt Lake City has proposed raising the 3/4-inch water fee from $1,871 to $5,577. The change takes effect 90 days after Council approval, so check SLC’s impact fee page before budgeting.
• Exemptions. Portland reports that new-housing permits issued August 15, 2025 through September 30, 2028 may be exempt from SDCs. Denver Water offers a 20% SDC credit for qualifying water-efficient projects.
• Split providers. In Orlando, OUC serves water inside city limits, but sewer comes from the City of Orlando. Unincorporated addresses are served by Orange County Utilities, which charges its own $2,790 per ERC water capital charge.
• Teardowns. Replacing an existing home can earn credit for the old service if you ask before demolition; see tap fee credits on a teardown rebuild.
