Backflow Prevention Device Certification in Portland, Oregon (2026)
Your restaurant's water service can be shut off without a valid Backflow Prevention Device Certification from the Portland Bureau of Environmental Services (BES), also known as a cross-connection control certificate. This annual requirement protects public water from contamination, and failure to maintain certification violates Oregon Health Authority (OHA) plumbing code and local water district rules. Key facts:
- 68 fields — ApronPrep auto-fills 56
- Varies — Testing fees are paid directly to a certified tester; the city does not charge a filing fee for the certification itself
- Annual renewal frequency; processing timeline varies

Why You Need a Backflow Prevention Device Certification
This certification is a mandatory requirement to operate your food service establishment in Portland, primarily enforced under the Portland City Code Chapter 17.39, which governs sewer and drainage regulations, and the water connection standards set by the Portland Water Bureau (PWB). Your building's plumbing system is considered a potential cross-connection point to the public water supply. The certification proves you have installed and are maintaining an approved backflow prevention device—typically a Reduced Pressure Zone (RPZ) assembly—to stop contaminated water from your kitchen (containing grease, cleaning chemicals, or food waste) from flowing backwards into the municipal drinking water lines. This is a non-negotiable condition for receiving or maintaining a water service connection for a commercial kitchen.
Without a current, passing certification on file, you face several significant operational and financial consequences. Based on Portland Bureau of Environmental Services (BES) and PWB enforcement protocols, common penalties include:
- Service Disconnection: The Portland Water Bureau can physically shut off your water service, effectively closing your restaurant until compliance is achieved.
- Fines and Administrative Fees: You become subject to daily fines for non-compliance, plus all costs associated with re-inspections and any required emergency remediation work.
- Required Remediation & Permit Impacts: You may be forced to immediately hire a licensed tester and plumber, potentially during an emergency shutdown. Failure to comply can also trigger a review and possible revocation of your overall business license or food service permit.
- Insurance and Lease Implications: A water service interruption constitutes a business interruption. Your commercial property or business insurance may not cover losses from a violation-caused shutdown. Many commercial leases also require tenants to maintain all required permits, putting your lease in default.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, the Portland Water Bureau has mandated electronic submission of all test reports directly by licensed testers into its online portal, eliminating the option for owners to submit paper forms themselves.
Who Needs a Backflow Prevention Device Certification?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required by Portland Water Bureau Cross-Connection Control Ordinance § 21.16.120 for any food service business directly connected to the public water system, as most have plumbing fixtures (like dishwashers, prep sinks, and soda machines) considered cross-connection hazards. |
| Bar / Nightclub | Required | Required under the same Portland Water Bureau ordinance; bars and nightclubs pose a significant hazard due to direct connections for glasswashers, ice machines, post-mix soda systems, and potentially chemical dispensers that could contaminate the water supply. |
| Food Truck | Not Required | Typically exempt if the truck operates with a self-contained potable water tank and does not have a permanent, direct connection to a city water line at a commissary; certification is required only for the commissary's fixed plumbing system, not the mobile unit itself. |
| Coffee Shop / Café | Required | Required because commercial espresso machines, steam wands, and dipper wells create a direct cross-connection under Portland's plumbing code, necessitating an approved backflow prevention device and annual testing to protect public water. |

56 of 68 auto-filledBusiness Legal Name
textEnter the exact legal name of your business entity as registered with the Oregon Secretary of State, which must match your Articles of Incorporation, Organization, or your Fictitious Business Name Statement exactly, including punctuation and abbreviations like 'LLC' or 'Inc.'.
COMMON MISTAKE: Entering a DBA or trade name instead of the registered legal entity name causes the Portland Water Bureau to reject the application for non-matching records.
DBA / Trade Name
textEnter the 'Doing Business As' or trade name customers know you by; if your business operates solely under its legal name, you may write 'SAME' or leave this field blank, but check the form instructions for specific guidance.
COMMON MISTAKE: Leaving this field blank when the business has a registered DBA can cause processing delays as reviewers seek clarification.
Property Street Address
textEnter the complete street address of the restaurant's physical location where the backflow prevention device is or will be installed, including suite or unit number, as it appears on your lease or property deed.
COMMON MISTAKE: Using a P.O. Box, an incomplete address (missing 'NW', 'SE', etc.), or the owner's home address results in immediate rejection because the Water Bureau cannot locate the service connection.
Property City
textEnter 'Portland'; do not abbreviate or use surrounding municipality names like 'Beaverton' as the device certification is specific to Portland Water Bureau jurisdiction.
Property State
textEnter 'OR' or 'Oregon'; consistency with other state fields on the form is required to avoid automated flagging.
Property ZIP Code
textEnter the full 5-digit ZIP code for the property; using the ZIP+4 extension is acceptable but not required by the Portland Water Bureau for this form.
COMMON MISTAKE: Entering a ZIP code for a mail center or an incorrect code for the property's neighborhood leads to correspondence and permit delivery failures.
Mailing Address Different
checkboxCheck this box only if correspondence (invoices, approval letters) should be sent to an address other than the property address; if unchecked, all subsequent mailing address fields should be left blank.
COMMON MISTAKE: Checking the box but leaving the mailing address fields incomplete, or not checking it when the addresses are different, causes the Water Bureau to send critical documents to the wrong location.
Mailing Street Address
textIf 'Mailing Address Different' is checked, enter the complete street address or P.O. Box for receiving official mail; this is often an owner's office or a management company address.
COMMON MISTAKE: Entering a residential home address when a business mailing address is required can lead to privacy issues and document handling delays.
Mailing City
textEnter the city for the mailing address; this can be different from Portland if your business office is located elsewhere, such as 'Lake Oswego'.
Mailing State
textEnter the two-letter state abbreviation (e.g., 'OR', 'WA') for the mailing address.

Top 5 Backflow Prevention Device Certification Mistakes
1. Incorrect Device Serial Number or Model
Entering the device's make or generic model (e.g., 'Watts 009') instead of the unique serial number stamped on the unit. The Portland Water Bureau's cross-check rejects mismatches, as the serial number is the official identifier for their device registry. This adds 2–3 weeks for correction and verification. Find the serial number on the device's body or collar plate.
2. Using an Expired or Unlicensed Tester ID
Listing a tester whose Oregon Department of Human Services (DHS) certification expired or is for a different county. Portland only accepts testers licensed specifically for Multnomah County. An expired license causes automatic rejection, delaying your submission until you hire a qualified tester. Verify your tester's current license number on the Oregon DHS online licensee lookup before filing.
3. Incomplete Test Results Table
Failing to fill all columns in the test results section, especially leaving the 'Static Pressure Differential' blank. The form requires specific PSI readings for each test valve (pressure relief, check, etc.). Partial data is treated as an invalid test, requiring a re-test and new submission. Ensure your certified tester completes every required field on their test report before you transcribe it.

Timeline: Varies
Step 1: Contact Portland Bureau of Environmental Services (BES) to verify backflow prevention device certification requirements for your commercial water connection
Call or email the Portland BES Cross-Connection Control Program to confirm if your specific water connection, as listed on your water utility account, requires a Reduced Pressure Zone (RPZ) or other approved device. Have your utility account number and the Standard Industrial Classification (SIC) code for your restaurant ready. This initial verification is critical — incorrect device classification is a common cause for failed submissions.
Step 2: Hire a certified backflow prevention device tester (Oregon Health Authority certified) to inspect and test your backflow prevention device
Engage a tester certified by the Oregon Health Authority from BES's approved list. The tester will physically inspect the device for proper installation and perform a hydraulic test. Schedule this when your restaurant is closed or during low water use, as the test involves shutting off and manipulating water valves, which can disrupt kitchen operations.
Step 3: Obtain the tester's certification documentation and test report results
Your hired tester must provide you with a completed, signed "Annual Test and Maintenance Report" form, which includes their OHA certification number, the device's model/serial number, and all test results (e.g., relief valve opening point, differential pressure). Insist on receiving a digital PDF copy for easier submission; a blurry or incomplete paper form is a top rejection reason.

See all co-required forms and how they connect to your compliance dossier.
See All RequirementsThe timeline varies significantly based on the device's installation and testing status. If the device is already installed and passes a test by a state-certified tester, you can submit the test report immediately for processing. If a new device is required as part of a Building Permit project, approval is tied to that permit's timeline, which can take several weeks or more. Contact the Portland Water Bureau's Cross Connection Control Program to confirm current processing times.
The city does not charge a separate government filing fee for the certification itself. Your primary costs are for the required annual or tri-annual testing by a state-certified backflow assembly tester, which typically ranges from $75 to $200 per test. You may also face significant costs for installing or repairing a device if required, similar to other construction-related permits like an Electrical Permit. Not legal advice — verify service costs with licensed testers.
No, certifications are specific to the device, its location, and the service address. If you move your business, you must have the backflow prevention assembly(s) at the new location tested and certified. The permit file is tied to the property's water account, as stated in Portland Water Bureau rules. You will need to initiate a new certification application for the new premises.
Certification renewal is required annually for most commercial food service establishments, per Portland Water Bureau regulations. Some lower-risk devices may qualify for tri-annual (every three years) testing, but this is determined by the Bureau's hazard assessment of your facility. You must hire a state-certified tester to perform the required test and submit the report to the Bureau each cycle to maintain compliance.
The 'inspection' is the performance test conducted by your hired, state-certified backflow assembly tester. They will test the device to ensure it prevents any reverse flow of water under both back-siphonage and back-pressure conditions. The tester submits the official test report to the Portland Water Bureau; the Bureau may then conduct its own periodic audit or field verification of the device and its installation location.
