Why You Need a Backflow Prevention Device Certification
The Backflow Prevention Device Certification is required in San Antonio to protect the public water supply from contamination. The mandate originates from the San Antonio City Code, Chapter 34, Article X, "Cross-Connection Control and Backflow Prevention." This ordinance empowers the city's water utility, San Antonio Water System (SAWS), to administer the program. Its legal authority is further reinforced by Texas Commission on Environmental Quality (TCEQ) rules and local sewer use regulations. You must submit certification annually to SAWS, confirming that your restaurant's backflow prevention assemblies have been tested by a state-licensed tester and are functioning correctly to prevent grease, chemicals, or other contaminants from flowing back into the public mains.
Failure to obtain and maintain this certification carries significant penalties. Based on common enforcement actions and the cited city code, the primary consequences include:
- Service Disconnection: SAWS can physically terminate your water service, halting all restaurant operations until compliance is achieved and a reconnection fee is paid.
- Fines and Penalties: The city can levy administrative fines for non-compliance. While specific dollar amounts vary by violation, daily penalties can accumulate, adding substantial unexpected costs.
- Required Remediation: You will be required to immediately hire a licensed tester, perform any necessary repairs, and submit a passing test report, incurring labor and parts costs on top of any fines.
- Permit & Insurance Risk: Operating without valid certification violates your water utility agreement and can jeopardize your occupancy permit. It may also violate your commercial property insurance policy, potentially negating coverage for water-related incidents.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: In 2026, SAWS transitioned to a fully digital submission portal for all Backflow Prevention Device Test Reports, eliminating the need for paper forms and requiring all certified testers to submit results electronically.
Who Needs a Backflow Prevention Device Certification?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | All food establishments connected to the municipal water supply must submit annual test reports for backflow prevention assemblies, as mandated by the San Antonio Water System (SAWS) Cross-Connection Control Program § 18-4. |
| Bar / Nightclub | Required | Required if the premises include any water-based appliances (e.g., ice machines, sinks, dishwashers) connected to the city water line, per SAWS regulations for commercial properties with auxiliary water systems. |
| Food Truck | Required | Required if the mobile unit has a potable water system onboard, as SAWS and city health codes apply to all temporary and permanent food service connections to prevent contamination of the public water supply. |
| Coffee Shop / Café | Required | Almost always required due to the standard use of water boilers, espresso machines, and ice machines, all of which are classified as potential cross-connection points under SAWS Ordinance No. 2015-02-12-0082. |

COMMON MISTAKE: Writing 'OK' or 'Good'; the city requires a specific status description for their inspection records.
Certified Tester Hired
checkboxCheck this box only if you have a signed contract or agreement with a tester who holds a current Backflow Prevention Assembly Tester (BPAT) certification from the Texas Commission on Environmental Quality (TCEQ).
COMMON MISTAKE: Checking the box after merely contacting a tester; 'hired' means a formal engagement for the specific test.
Tester Name/Company
textEnter the full legal business name of the certified testing company or the full name of the individual certified tester you have hired, exactly as it appears on their TCEQ certification.
COMMON MISTAKE: Entering a generic plumbing company name that is not the specific entity holding the BPAT certification.
Tester Contact Phone
textProvide the direct, daytime contact phone number for the hired tester or their company's scheduling office.
COMMON MISTAKE: Providing a personal cell number or a main business line that does not connect directly to the backflow testing department.
Needs Help Finding Tester
checkboxCheck this box if you do not have a tester hired and require a referral list from the San Antonio Water System (SAWS) of approved, certified local testers.
COMMON MISTAKE: Checking this box after already hiring a tester, which creates confusion and may delay processing.
Preferred Test Date
textEnter the specific date you and your hired tester have agreed upon for the on-site test, in MM/DD/YYYY format. If not scheduled, write 'To be determined.'
COMMON MISTAKE: Entering a weekend date or a holiday; SAWS inspectors typically only validate tests conducted on business days.

Top 5 Backflow Prevention Device Certification Mistakes
1. Incorrect or Missing Test Report Data
The most common cause of rejection is submitting a test report form with incomplete data, such as missing static or residual pressure readings, or failing to include the certified tester's signature and license number. Based on ApronPrep's analysis, this mistake adds 2-3 weeks as the application is returned, and you must pay to have a licensed tester re-perform the test and complete a new form. Avoid this by ensuring your tester provides a fully completed 'Backflow Prevention Assembly Test and Maintenance Report' (SAWS Form 206) with every required field filled out.
2. Submitting the Wrong Form Version
Using an outdated San Antonio Water System (SAWS) test form is a frequent error. The forms and required data points are updated periodically; using an old version results in an immediate administrative rejection. This delay forces you to contact your tester for a re-test on the current form. Always verify you are using the most recent version, which can be downloaded directly from the SAWS Cross-Connection Control program website, and confirm the form number and revision date before submission.
3. Mismatched Premise or Device Information
Inconsistencies between the service address, premise number, or device serial number on the test report and the device information on file with SAWS will halt processing. For example, listing '123 Main St' when SAWS has the account under 'Suite B, 123 Main Street' triggers a manual review. To avoid this, cross-check the exact premise address and device details (make, model, size, serial number) against your most recent SAWS water bill or the initial installation permit before the tester completes the form.

Timeline: Varies
Step 1: Verify your restaurant has a backflow prevention device installed on the commercial water connection (required by San Antonio local sewer use regulations)
Locate your backflow prevention assembly—it's typically where the main water line enters the building or at specific points like irrigation connections or boiler feeds. You'll need its manufacturer, model, size, and serial number for the test report. Buildings constructed after 1980 almost always have them, but older properties may need an installation assessment, which can take 1-2 weeks and require a plumber. Not having a required device is a direct violation of San Antonio Water System (SAWS) rules and can trigger a non-compliance notice.
Step 2: Hire a Texas Commission on Environmental Quality (TCEQ) licensed Backflow Prevention Assembly Tester (BPAT) - consult the SAWS Approved Backflow Testers list
Select a tester from the official SAWS Approved Backflow Testers directory, not a general plumber. Verify their TCEQ license is current by checking the TCEQ online license search. Get a written quote—typical testing fees range from $75 to $200 per device, plus trip charges. Booking a tester during peak renewal periods (like December-January) can take 2-3 weeks, so schedule early. Using an unapproved tester voids the certification and requires a re-test.
Step 3: Schedule annual testing with your certified tester (required annually per San Antonio Water System regulations)
Coordinate a 30-60 minute window for the tester to access the device, which may require shutting off water briefly. Have your restaurant's SAWS account number and service address ready for the report. The tester must perform the test within the calendar year of your last certification; missing the annual deadline results in a $50 SAWS re-inspection fee and potential water service interruption. Most testers recommend scheduling 60 days before your annual due date to avoid penalties.

See All RequirementsProcessing time varies significantly. Once you submit your test report from a licensed tester to the San Antonio Water System (SAWS), approval can take from a few days to several weeks, depending on their backlog and the completeness of your submission. To avoid delays, ensure your Building Permit is finalized first, as the device installation is part of that process. Contact SAWS's Cross-Connection Control Program directly for current processing estimates.
The government filing fee paid to the San Antonio Water System (SAWS) ranges from $100 to $300, as per their current fee schedule. This is separate from the cost to install the device and hire a licensed tester to perform the required annual test, which typically costs $150-$400. Not legal advice—verify exact fees with SAWS.
No, certifications are site-specific and cannot be transferred. Each physical location must have its own device tested and certified because water system configurations differ. When you move, you must complete a new application and inspection process for the new premises, similar to obtaining a new Certificate of Occupancy. Contact SAWS to close the certification at your old address and initiate one for the new location.
You must renew your certification annually. The San Antonio Water System (SAWS) requires the device to be tested by a licensed backflow prevention assembly tester every year, and the test report must be submitted to SAWS for recording. Failure to submit the annual test report on time can result in water service interruption, as stated in SAWS's rules and regulations.
A licensed tester performs a functional test on the installed device to ensure it operates correctly and prevents contaminated water from flowing back into the public supply. They check for proper installation, location, and that the device matches the hazard level of your business (e.g., a restaurant is typically a high hazard). The tester then submits the official test report directly to SAWS; you do not need to be present for a separate city inspection unless it's part of the initial Building Permit finalization.
