Why You Need a Backflow Prevention Device Certification
Aurora requires a Backflow Prevention Device Certification to protect the public water supply from potential contamination, as mandated by local code. Specifically, the Aurora Municipal Code, Title 10 (Water and Sewers), Chapter 4 (Cross‑Connection Control) establishes the rules for backflow prevention. The city's Plumbing and Building Department enforces these regulations, requiring annual testing and certification for all commercial food service establishments connected to the city water main. This is separate from your state-level food service permits and is a condition of maintaining your water service connection.
Operating without a current, certified test report from a licensed tester carries immediate and costly consequences. Failing to comply is a violation of your water service agreement, which can trigger administrative actions that directly impact your ability to operate. Based on common enforcement actions in Aurora, the primary penalties include:
- Water Service Disconnection: The city can physically shut off the water supply to your premises for non-compliance, effectively forcing a closure.
- Fines and Required Remediation: You will incur daily fines until compliance is restored, plus the cost of any emergency repairs or device replacement ordered by the city inspector.
- Lease and Insurance Implications: A water service violation can breach your commercial lease terms and may void clauses in your property or business liability insurance related to code compliance.
- Permit Revocation Risk: The Aurora Health Department can suspend or revoke your food service operating permit due to a critical public health violation stemming from an unprotected water connection.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2026, Aurora now requires electronic submission of all backflow test reports directly through the city's online portal, eliminating the previous paper‑based submission to the Building Department.
Who Needs a Backflow Prevention Device Certification?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required because these facilities have permanent plumbing connections with potential cross-connections, such as dishwashers, sinks with hose bibs, or ice machines, triggering Aurora Water Department requirements. |
| Bar / Nightclub | Required | Required due to direct plumbing connections for bar sinks, glass washers, and post-mix soda systems, which are considered contamination hazards under the Illinois Plumbing Code and Aurora's Cross-Connection Control Program. |
| Food Truck | Not Required | Typically exempt because food trucks are not connected to a permanent water supply; they utilize onboard potable water tanks and are not considered a fixed cross-connection point requiring annual certification. |
| Coffee Shop / Café | Required | Required if the establishment has a direct connection to the municipal water supply for espresso machines, dipper wells, or any equipment with a submerged inlet, as defined by Aurora's ordinance. |

26 of 31 auto-filledBusiness Legal Name
textEnter the exact legal name of your business as it is registered with the State of Illinois, matching your Articles of Incorporation, LLC filing, or assumed name certificate.
COMMON MISTAKE: Using a DBA ('Doing Business As') name instead of the registered legal entity name, which will cause the application to be rejected as the permit must be issued to the legal owner.
Business Service Address
textEnter the full street address where the backflow prevention device is or will be installed, which must match the location on your Aurora business license and water utility account.
COMMON MISTAKE: Listing a PO Box, corporate office, or home address instead of the restaurant's physical service address, which delays processing as the inspector cannot locate the device.
Primary Contact Name
textEnter the full name of the person responsible for the device (e.g., general manager, facility manager, or owner) who can grant access for inspection and receive official correspondence.
Primary Contact Phone
textProvide a direct, working phone number for the primary contact, including area code, where they can be reached during business hours for scheduling inspections.
COMMON MISTAKE: Providing a disconnected number or a main restaurant line that routes to a busy host stand, causing missed inspection calls and rescheduling delays.
Primary Contact Email
textEnter a valid, monitored email address for the primary contact where the Aurora Water Department can send test report forms, inspection notices, and certificate approvals.
Backflow Prevention Device Installed
checkboxCheck this box only if a Reduced Pressure Zone (RPZ) or other approved backflow assembly is already physically installed on your water service line.
COMMON MISTAKE: Checking this box when a device is not yet installed, which leads to a failed inspection, a violation notice, and a requirement to resubmit the entire application.
Device Installation Required
checkboxCheck this box if your facility requires a new backflow prevention device to be installed; this triggers a different permit pathway and initial inspection.
COMMON MISTAKE: Failing to check this box when installation is needed, resulting in an application for certification being submitted for a non-existent device, which is automatically rejected.
Device Location Description
textDescribe the device's physical location precisely (e.g., 'In basement mechanical room, south wall, next to water heater' or 'In exterior meter pit on east side of building').
COMMON MISTAKE: Using vague terms like 'in the back' or 'by the water main,' which fails Aurora's requirement for a specific description and causes inspector delays or aborted visits.
Device Accessibility Status
textState whether the device is currently accessible for testing and inspection (e.g., 'Yes, unlocked and clear' or 'No, locked room—key at front desk').
COMMON MISTAKE: Claiming the device is accessible when it is behind locked doors or obstructed by storage, leading to a failed inspection and a re-inspection fee.
Accessibility Notes
textProvide any specific instructions for access, such as lockbox codes, contact persons for entry, or times when the area is unlocked.
COMMON MISTAKE: Leaving this field blank when special access is needed, resulting in the inspector being unable to perform the test and charging a $75 re-inspection fee.

Top 5 Backflow Prevention Device Certification Mistakes
1. Submitting a Non-Certified Tester's Report
Attempting to file a report completed by someone who is not a State of Illinois-licensed Cross-Connection Control Device Inspector (CCCDI). Aurora Public Works - Water Production Division rejects these immediately because only a licensed CCCDI is legally authorized to certify the device. Verify your tester's license is current with the Illinois Department of Public Health before scheduling the test.
2. Incorrect or Missing Device Information
Entering a wrong or incomplete manufacturer, model, serial number, or location ID on the test report form. This creates a mismatch with Aurora's water system inventory and halts processing. For example, entering 'Watts 009QT' instead of the full model 'Watts 009QT3' is a common error. Always pull the exact details from the metal tag on the device itself, not from an invoice or memory.
3. Failing to Correct All Test Failures Before Submission
Submitting a report that notes a device 'failed' its initial test without including documentation that repairs were made and the device subsequently passed a re-test. Aurora requires proof the device is operational at the time of certification. Submitting a failed report adds 2-3 weeks as you must re-schedule the tester, pay for a second test, and restart the filing process.

Timeline: Varies
Step 1: Verify that your commercial water connection has a backflow prevention device (RPZ - Reduced Pressure Zone device) installed by a licensed plumber
Locate your backflow preventer, typically installed on your main water line before the water meter. You need to confirm it's the correct type (RPZ for high hazard) and that the installation was signed off by an Illinois-licensed plumber with a valid permit. If your device is missing or not the right type, you cannot proceed to testing, which adds 2-4 weeks for a new installation.
Step 2: Contact a City of Aurora-approved licensed plumbing contractor to schedule backflow preventer testing and certification
You must hire a contractor from Aurora Water's approved list, found on the city website. Contact at least 2-3 providers to get quotes, as fees vary widely. Schedule the test for a time when you can provide immediate access to the device; commercial contractors often book 1-2 weeks out.
Step 3: Schedule the annual certification appointment with the licensed contractor
Formally book the test appointment, ensuring the contractor has your correct business name, address, and water account number. Provide them access to the device's location (clear any obstructions) and have your water service on. Missed appointments typically incur a rescheduling fee and delay compliance by a week or more.

See All RequirementsThe processing timeline varies and is often determined by the availability of city inspectors to perform the required test, not by a standard application review. After submitting the certification paperwork to the Public Works Department, you must schedule the test, which could take several days to a few weeks depending on their backlog. Contact the Aurora Public Works Department to confirm current scheduling wait times.
The City of Aurora does not charge a direct government filing fee for the certification of an existing device. However, you are responsible for paying a licensed tester, which typically costs $75–$150 per device. A new installation requires a separate Building Permit, which does have associated fees. Not legal advice — verify with the Aurora Public Works Department.
No, certifications are site-specific and cannot be transferred. The certification is linked to the physical device and property address where it is installed. If you move your business, you must have the new location's device certified, which may require a new Certificate of Occupancy process first, as per Aurora's cross-connection control rules.
You must renew your backflow prevention device certification annually, as mandated by the Aurora Municipal Code. The city will send a reminder notice, but it is the property owner's responsibility to have the device tested by a licensed professional and submit the test report by the deadline. Failure to renew can result in water service interruption, per the Public Works Department.
A licensed tester you hire will perform a mechanical test on the device to ensure it prevents water from flowing backward into the public supply. They will check for proper installation, operation, and any leaks or defects. After a passing test, the tester files the official report with the city; there is typically no city inspector present unless it's part of a larger construction project requiring a final inspection.
