Why You Need a Water and Sewer Connection Permit
Your restaurant cannot legally open without a valid Water and Sewer Connection Permit in Portland. This permit is mandated by Portland City Code Title 17 (Public Works) and Title 24 (Sewers and Drains), specifically under provisions governing new service connections, flow limits, and compliance with the city's Pretreatment Program for food service establishments. The Portland Water Bureau and the Bureau of Environmental Services issue this permit jointly. It is not a simple utility sign-up; it is a formal review that ensures your planned water usage, wastewater discharge (especially grease and solids), and the physical connection to city mains comply with engineering standards and environmental regulations.
Operating without this permit, or with an improper connection, triggers immediate enforcement action and financial penalties. Common consequences include:
- Service Disconnection & Fines: The city can physically shut off your water and sewer service. You will face daily fines until compliance is achieved. Past cases show fines accumulating at rates specified in Portland City Code.
- Required Remediation & Permit Revocation: You may be forced to halt construction or cease operations to install required grease interceptors, backflow prevention devices, or correct improper piping at your own expense. Your permit can be revoked, requiring a full re-application.
- Lease & Insurance Implications: Most commercial leases require proof of all utility permits. Failure to obtain this permit can be grounds for lease termination. Similarly, property and business insurance policies may be voided if a facility operates with an unpermitted or non-compliant utility connection, especially if it leads to a sewer backup or water damage claim.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, Portland has fully integrated its Water and Sewer Connection Permit application into its online Portland Maps permit portal, eliminating the previous requirement for separate paper submissions to the Water Bureau and Environmental Services, though in-person consultations for complex sites are still recommended.
Who Needs a Water and Sewer Connection Permit?

25 of 30 auto-filledProperty Street Address
textEnter the restaurant's exact street address where water and sewer connections will be installed, such as '1234 SW Main Street'. Do not include unit or suite numbers; use the official site address from your property deed.
COMMON MISTAKE: Entering the business's mailing address or a neighboring address. This mismatch causes Portland Water Bureau review to be flagged, requiring a correction letter from your landlord.
City
textEnter 'Portland'. The Portland Water Bureau only serves addresses within city limits; other cities like Beaverton or Gresham require a different water utility application.
State
textEnter the two-letter state abbreviation 'OR'. This is used to verify jurisdiction against county water district records.
ZIP Code
textEnter the correct 5-digit ZIP code for the property site. This is cross-referenced with the Portland Water Bureau's service area map; using the wrong ZIP can route your application to the wrong review desk.
COMMON MISTAKE: Using a postal delivery ZIP code that differs from the property's jurisdictional ZIP, which adds 1-2 business days to processing for address verification.
Property Ownership Status
textCheck the box or enter either 'Owner' or 'Tenant'. This determines who is legally responsible for the water service and any associated capacity charges.
COMMON MISTAKE: A tenant selecting 'Owner' without providing the required landlord authorization document, which results in an automatic administrative hold on the application.
Property Deed
textIf you own the property, provide the Multnomah County Assessor's document number or a copy of the recorded deed. This proves you have the right to request a new utility connection.
COMMON MISTAKE: Submitting a preliminary title report instead of the final, recorded deed, which the Water Bureau cannot accept as legal proof of ownership.
Lease Agreement
textIf you are a tenant, upload the full, signed commercial lease agreement. The Water Bureau requires pages showing the lease term, property address, and tenant responsibilities for utilities.
COMMON MISTAKE: Submitting only the first page or a summary page, which lacks the necessary clauses showing the tenant is authorized to contract for water service.
Authorization to Make Improvements
textTenants must provide a separate, signed letter from the property owner authorizing the specific water and sewer connection work. The letter must include the owner's contact information and the project address.
COMMON MISTAKE: Providing a generic 'permission to alter premises' clause from the lease instead of a specific, project-focused authorization letter. This is the top cause of rejection for tenant applicants.
Business Legal Name
textEnter the exact legal name of your business entity as registered with the Oregon Secretary of State, such as 'XYZ Restaurant Group LLC'. This name will be printed on the water bill.
COMMON MISTAKE: Using the restaurant's 'Doing Business As' (DBA) name instead of the legal entity name, causing a mismatch with Secretary of State records and delaying the account setup.
Food Service Facility Type
textEnter your establishment's primary use, such as 'Full-Service Restaurant', 'Fast-Food', 'Bar/Tavern', or 'Catering Kitchen'. This determines the water demand calculations and meter size.
COMMON MISTAKE: Selecting a generic term like 'Restaurant' instead of the more specific category required by the Water Bureau's plumbing code, which can lead to an undersized meter being specified.

Top 5 Water and Sewer Connection Permit Mistakes
1. Using Incorrect Property Legal Description
Entering the street address only instead of the full legal description (lot, block, subdivision) from the property deed or title report. The Portland Water Bureau requires the complete legal identifier for system mapping and to avoid service conflicts with adjacent properties. Applications submitted with just an address are typically placed on hold, which can add 1–2 weeks while you gather and resubmit the correct documentation.
2. Underestimating Required Fixture Unit Count
Manually counting plumbing fixtures incorrectly or using outdated values. The total Fixture Unit count determines your required pipe sizing and capacity fees. For example, counting a commercial kitchen's pre-rinse spray valve as 1 unit when it's actually 5 Fixture Units can lead to an undersized service line design, causing a costly plan rejection. Use the Portland Water Bureau's official Fixture Unit Table (available in their design standards manual) to ensure accuracy.
3. Submitting Incomplete or Unsealed Site Plans
Failing to include a professional engineer's or surveyor's seal on the site plan showing the proposed connection location and all existing utilities. Unsealed drawings or sketches are not accepted for permitting. You must submit a plan sealed by an Oregon-licensed professional that clearly shows distances from the main to the meter, property lines, and any conflicts. This is the most common cause of immediate application return, delaying your project start by 2–3 weeks.

Timeline: 6–14 Weeks
Step 1: Contact Portland Water Bureau and Bureau of Environmental Services to request Water and Sewer Connection Permit application
Call the Portland Water Bureau’s Development Services (503-823-7368) and email the Bureau of Environmental Services (BES) at bes.permits@portlandoregon.gov to request the application packet, which includes forms EN-101 and EN-102. Have your project address, tax lot number, and project type (new food service) ready. Initial contact typically takes 1–3 business days to get the correct forms, as requests sent to the wrong department are the most common delay.
Step 2: Prepare site plans showing building layout, water/sewer line locations, and connection points to municipal infrastructure
Hire a licensed civil engineer or surveyor to draft detailed site plans at a scale of 1" = 20' or 1" = 30', showing all existing and proposed structures, property lines, and the exact location of the proposed water service line and sewer lateral connection to the city main. You must also include a Grease Interceptor Detail drawing if required by BES. This engineering work is the most time-consuming preparatory step and must meet Portland Public Works Standard Drawings.
Step 3: Complete permit application form with property details, business type (food service), and connection specifications
Fill out forms EN-101 (Water Connection) and EN-102 (Sewer Connection) with precise data: pipe diameters (typically 1" for water, 4" for sewer), material types (copper for water, PVC for sewer), depth of cover, and the exact distance from your building to the city main. For food service, you must specify the grease interceptor model and capacity. A single error in pipe sizing or material spec is a top reason for application rejection, adding 1–2 weeks for resubmission.

See All RequirementsProcessing times vary significantly based on the scope of your project, plan review needs, and inspection scheduling. For a straightforward connection, the review itself may take 2–4 weeks from submission of a complete application. The Building Permit process often dictates the final timeline, as the connection permit is typically issued as part of that larger review cycle. Contact the Bureau of Development Services to confirm current timelines for your specific project type.
Government filing fees for a water and sewer connection permit in Portland range from $500 to $2,000. The final cost is calculated based on factors like pipe size, connection type, and street opening requirements. These fees are set by the Portland Bureau of Transportation and Portland Water Bureau per their respective fee schedules, and are separate from any contractor costs for the physical connection work. Not legal advice — verify final costs with the Bureau of Development Services.
No. A water and sewer connection permit is specific to the approved plans and physical address. It cannot be transferred to a different location. If you move your business, you must apply for a new permit at the new address, which includes a new site plan review. The application process is similar but may require a new Certificate of Occupancy depending on the new space's existing conditions.
You do not renew this permit. Once the connection is installed, inspected, and approved by the city, the permit is considered closed and fulfilled. However, the physical backflow prevention device required as part of the connection must be tested and certified annually, which is a separate requirement. Your ongoing responsibility is to maintain the connection in compliance with city codes.
A city inspector verifies that the installation matches the approved plans and meets Portland plumbing and public works codes. They check pipe materials, sizing, slope, proper support, trench compaction, and the correct installation and type of the required backflow prevention assembly. The inspection typically occurs after the trench is open but before it is backfilled, so the work is visible. Failure can require rework and a re-inspection fee, delaying your overall project schedule.
