Tacoma Water and Sewer Tap & Connection Fees (2026)
Tacoma Water, a division of Tacoma Public Utilities, provides water inside Tacoma, and the City of Tacoma Environmental Services Department provides wastewater service. For a new single-family home with the standard 5/8-inch meter, the 2026 charges we verified come to $9,243: a $1,204 water system development charge (SDC), a $4,700 water service construction charge (the tap and meter install), and a $3,339 wastewater SDC. The most important local caveat is timing: both utilities just overhauled their fee structures. The water SDC and tap charges are on a multi-year phase-in schedule that raises them again every January 1 through 2029-2030, and the wastewater SDC did not exist before July 1, 2026 — it replaced an older sewer connection-charge-in-lieu-of-assessment program. For how this compares nationally, see our guide to the cost to connect to city water.
Tacoma connection fees at a glance
The table below lists every Tacoma row we verified, each tied to its meter size and effective date. The water SDC and water service construction charge come from Tacoma Municipal Code (TMC) 12.10.310 and 12.10.250, which now list five annual columns (2025/2026 through 2029/2030); we used the column in effect as of this research date. The wastewater SDC comes from the City’s Wastewater SDC FAQ, published only for the standard 5/8-inch residential meter. The two Sanitary Sewer Connection rows and the Site Development Permit formula row come from the City’s 2026 land-use permit fee schedule and cover the physical tap-in work; read the worked example below for which one actually applies to new construction. Tacoma Power rows appear too, for readers budgeting electric service alongside water and sewer, but they are not part of this page’s water/sewer total.

Worked example: a new home in Tacoma
Assumptions: a detached home inside Tacoma city limits, connecting to an existing water main (not a brand-new subdivision main), one domestic meter, and a side sewer that still needs to tap the public main. Three meter-size cases for the two SDC-and-tap charges Tacoma bills directly:
Tacoma Water and Environmental Services charges, 2026 (SDC: TMC 12.10.310, effective 2/1/2026 tier; tap: TMC 12.10.250, effective 1/1/2026 tier; wastewater SDC: effective 7/1/2026)
| Charge | A: 5/8″ | B: 3/4″ | C: 1″ |
|---|---|---|---|
| Water SDC | $1,204 | $1,793 | $2,972 |
| Water service construction charge (tap) | $4,700 | $4,825 | $4,850 |
| Wastewater SDC | $3,339 | not published | not published |
| Total (5/8″ case complete) | $9,243 | $6,618 + sewer | $7,822 + sewer |
The standard for new residential domestic service is a 3/4-inch service pipe with a 5/8-inch meter (case A), which is why it is the only case with a complete total: the City’s Wastewater SDC FAQ publishes a dollar figure only for the 5/8-inch meter, even though it says the charge “depends on” meter size. If your plumber sizes the house for a 3/4-inch or 1-inch meter, budget for a higher wastewater SDC than $3,339, but we could not find the published number, so we left it out rather than estimate it.
The $4,700-$4,850 tap figures above are Tacoma Water’s charge for connecting to an existing main and are what most infill construction pays; a lower “Installation of Services and Meters on New Mains” schedule applies only when a developer has already stubbed services on a brand-new subdivision main.
What is not included in Tacoma fees
The SDCs pay for system capacity, and the water service construction charge covers Tacoma Water’s own crew work from the main to the meter. Still separate: the water line from the meter to the house, the side sewer trench and pipe from the house to the connection point, the building permit itself, and (as described above) the percentage-of-valuation site development component that actually authorizes the tap-in work. National estimates (methodology):
- Water line from meter to house: $30-$150 per foot, typical $50. At 30 feet, about $1,500.
- Side sewer: $50-$250 per foot, typical $100. At 50 feet, about $5,000.
- Street cut or bore, if the sewer or water main is across the street: $1,000-$10,000, typical $4,000. Tacoma’s fee schedule adds its own Paving ($3,350 in 2026) or Flagging ($1,025) charges when its crew does the restoration.
- Plumbing permit: $100-$1,300, typical $300.
Estimate utility connection costs
Estimates are planning figures, not quotes. Confirm fees and trench rules with your utility.
Budgeting electric service too? Tacoma Power’s published new-service figures (April 2025) are a $56 application fee, a $1,588 (overhead) or $608 (underground) connection fee, and a $153/$306 electrical permit fee — not part of the water/sewer total above.
How and when Tacoma fees are paid
TMC 12.10.045 requires payment of both the water service construction charge and the SDC before Tacoma Water will install a new connection; both are due at that time, not spread over the build. For meters 2 inches and smaller, TMC 12.10.310.G requires the SDC in full when the meter installation is requested; only larger commercial/industrial meters can arrange time payments. The wastewater SDC is due when a property applies for a new connection or increases its service capacity (for example, upsizing a water meter); the City’s FAQ says existing customers who aren’t changing their level of service don’t owe it. A Septic System Amnesty Program offers a 50% wastewater SDC reduction for properties connecting to sewer for the first time, subject to annual funding. A side sewer permit from Planning and Development Services is required before any new or repaired side sewer connects to the public system, and City inspectors must sign off on the work before it’s covered.
Upcoming changes in Tacoma
- Tacoma Water’s SDC and service construction charge both increase again on January 1, 2027 under the phased schedule set by Ordinance 29027 (passed March 25, 2025) and continue rising annually through January 1, 2029 (tap) and January 1, 2030 (SDC). Budgets built on this page’s numbers will be short within a few months if the project slips into the next calendar year.
- The wastewater SDC took effect July 1, 2026 and is brand new; there is no prior-year figure to compare against, and only the 5/8-inch residential amount is published.
- Tacoma Power’s connection and application fees are the most recent figures we could verify (dated April 7, 2025); Tacoma Power’s own fee page points to an internal “New Services Engineering” policy rather than a public table, so confirm current pricing with Tacoma Power before budgeting electric service.
How Tacoma compares with Seattle and Spokane
At the same 5/8-inch meter size, Tacoma’s combined water-and-wastewater SDC is $4,543 ($1,204 + $3,339) — a little over half of Spokane’s combined GFC of $8,362 ($3,475 + $4,887). Tacoma’s $4,700 tap (water service construction charge) is close to Seattle Public Utilities’ smallest published figure, a $4,800 3/4-inch non-arterial water service installation; Seattle’s combined SDC at that same 3/4-inch size is $9,500, well above Tacoma’s 3/4-inch water SDC of $1,793 (Tacoma’s 3/4-inch wastewater SDC isn’t published). Spokane doesn’t publish its own tap-and-meter charge at all — its code says the number is set separately each year, and the city’s document server blocked our request — so a true Spokane total is understated. See the Seattle tap fee page and the Spokane tap fee page for their full breakdowns.
Common questions about Tacoma fees
How much does a new water and sewer connection cost in Tacoma?
For a new single-family home with the standard 5/8-inch meter, the published 2026 charges are a $1,204 water SDC, a $4,700 water tap charge, and a $3,339 wastewater SDC, $9,243 in all. That excludes side sewer trenching and the building-permit-based site development fee that authorizes the physical tap-in.
What is Tacoma’s system development charge (SDC)?
A one-time fee on every new water or sewer connection (or meter upsize) that pays for system capacity. Tacoma Water’s SDC is set by meter size under TMC 12.10.310 and rises annually through 2030; the wastewater SDC, new as of July 1, 2026, works the same way but only the 5/8-inch figure is published.
Why is Tacoma adding a new wastewater SDC in 2026?
Ordinance 29085 created it, effective July 1, 2026, so growth-related sewer capacity costs fall on new development instead of existing ratepayers. It replaced the City’s older Connection Charge-in-Lieu-of-Assessment program for applications approved on or after that date.
How much does a Tacoma side sewer connection permit cost?
The standalone permit is $580: $130 permit issuance plus $450 to connect the house sewer to the City main. A brand-new single-family home under a combination building permit instead pays via the site development fee (65% of the building permit fee, itself 1.31% of the ICC valuation), so the flat $580 mainly applies to connecting an existing house.
Does a bigger water meter cost more in Tacoma?
Yes. A 3/4-inch meter raises the water SDC from $1,204 to $1,793 and the tap charge from $4,700 to $4,825; a 1-inch meter raises them to $2,972 and $4,850. The standard for new single-family service is a 3/4-inch service pipe with a 5/8-inch meter.
Does Tacoma Power charge a separate fee for new electric service?
Yes. The most recent published figures (April 2025) are a $56 application fee, a $1,588 (overhead) or $608 (underground) connection fee, and a $153/$306 electrical permit fee, separate from the water and sewer charges above.
