Water and Sewer Connection Permit in Tacoma, Washington (2026)
Your contractor cannot legally connect your new restaurant's plumbing to Tacoma's water mains, halting all construction, until you have a Water and Sewer Connection Permit from Tacoma Public Utilities (TPU).

Why You Need a Water and Sewer Connection Permit
Connecting a commercial food service business to Tacoma's municipal water and sewer systems is not discretionary—it's a legal prerequisite. Your restaurant must comply with local Tacoma Municipal Code (TMC) Title 15, specifically Chapter 15.08 for Water and Sewer Extensions, and the provisions of the Tacoma-Pierce County Health Department (TPCHD) Sewage Disposal Regulations. This permit is issued by the City of Tacoma's Environmental Services Department (formerly Public Works). The application triggers a review to ensure your planned connections meet city specifications for pipe sizing, location, and backflow prevention, and that your wastewater, particularly grease, complies with discharge limits to protect the public sewer system.
Failing to secure this permit before any plumbing work begins has immediate and costly practical consequences. Based on common enforcement actions and code violations in Tacoma, you risk:
- Service disconnection – The City can halt water/sewer service to an occupied building, forcing an immediate shutdown.
- Substantial fines and required remediation – Violations typically incur daily fines until compliance is achieved, plus you will be billed for the city's cost to inspect and correct any unauthorized connections.
- Project delays and permit revocation – Building or occupancy permits can be withheld or revoked, freezing your entire opening timeline.
- Lease and insurance complications – Operating without required utility permits can violate commercial lease terms and potentially void property or liability insurance coverage for any related damages.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, the City of Tacoma's Environmental Services Department has consolidated its permit application portal, moving all water and sewer connection applications to an online system to reduce in-person submittal requirements.
Who Needs a Water and Sewer Connection Permit?

| Restaurant (Full-Service) | Required | All new or remodeled full-service restaurants with indoor plumbing and fixtures require connection permits to ensure compliance with Tacoma Municipal Code §12.08 and City standards. |
| Bar / Nightclub | Required | Required for new construction or remodeling due to significant water usage for bar sinks, restrooms, and possibly a kitchen, per City of Tacoma Utility Extension and Connection Policy. |
| Food Truck | Not Required | Typically connects to a commissary's approved water/sewer system; direct city connection permit not required unless installing a permanent utility hookup at a fixed location. |

Top 5 Water and Sewer Connection Permit Mistakes
1. Selecting the Incorrect Connection Type
Choosing a standard domestic connection when your restaurant requires a high-volume commercial connection leads to immediate rejection. The Tacoma Public Utilities (TPU) review will halt processing, requiring a full resubmission. Always base your selection on your peak projected water use, which your equipment supplier or architect can provide.
2. Incorrect or Missing Site Plan Drawing
Submitting a generic property map without the specific details TPU requires is the most common cause of a 2–3 week delay. Your plan must show the exact location of the proposed connection, existing meters, and distances from property lines. Applications are rejected if the drawing isn't drawn to scale and signed/sealed by a licensed professional when required.
3. Entering a Mailing Address Instead of the Parcel/Situs Address
Providing a PO Box or a different corporate mailing address confuses the site inspection scheduling and can invalidate your permit. TPU cross-references this with county assessor records. Use the official physical address of the property where construction will occur, as listed on your lease or deed.

Step 1: Obtain the Water and Sewer Connection Permit application from the City of Tacoma Utilities Department
Download the official application from the City of Tacoma Utilities Customer Portal or pick up a paper copy from the Utility Administration office at 3628 S. 35th St. You'll need your property's legal description or parcel number ready. Applications without the correct form version are rejected.
Step 2: Complete the application form with property address, business details, and connection specifications
Enter precise property address, owner information, type of food establishment, and connection details (e.g., pipe size, fixture unit counts). Tacoma requires that all contact information matches your business license. Applications are often delayed for mismatched business entity names.
Step 3: Prepare site plans showing proposed water/sewer line connections and grease trap/interceptor locations
A licensed designer must prepare detailed site plans at a standard scale (e.g., 1"=20'), showing all existing and proposed plumbing lines, meter locations, and grease interceptor specs to Tacoma Municipal Code Chapter 13.04. Missing a floor drain detail is a common rejection reason.

See All RequirementsProcessing times vary significantly, often taking several weeks or more depending on project complexity and department review backlogs. You should plan for a timeline measured in weeks, not days, per the City of Tacoma Public Works Department's application guide. Contact the Development Review and Inspection Services team directly to get a current estimate for your specific project scope.
Government filing fees range from $150 to $500, as stated on the City of Tacoma Public Works fee schedule. The final cost depends on factors like pipe size, connection type, and project valuation. This fee does not include costs for required contractors, materials, or related permits like a Building Permit. Not legal advice—verify final costs with the Public Works Department.
No, water and sewer connection permits are site-specific and cannot be transferred. The permit is tied to the physical property address and the approved engineering plans for that location. If you move your business, you must apply for a new permit for the new address, as this process is governed by Tacoma Municipal Code Title 12.
This permit is typically a one-time approval for the initial installation and does not require periodic renewal. However, you are responsible for maintaining the connection to code standards, which may involve periodic Backflow Prevention Device Certification. Always confirm ongoing obligations with Tacoma Public Works, as requirements can change.
A city inspector verifies that the installation matches the approved plans and complies with Tacoma's engineering standards (TMC Title 12). They check pipe materials, joint sealing, depth, bedding, and proper connection to the city main. The inspection must be passed before backfilling the trench; failure results in re-work delays and potential re-inspection fees.
