1. Scope & Authority
The City of Upland enforces a Cross‑Connection Control / Backflow Prevention Program to protect its potable water supply from contamination due to backflow or cross‑connections. This program is carried out under the authority of California’s Code of Regulations, Title 17, and Upland’s municipal water and plumbing service regulations. Upland has established procedures for notifications, mandatory testing, and online submission of backflow assembly test results via an approved data management system. The City evaluates hazards, determines required protective devices, and oversees compliance by property owners and certified testers.
2. Responsibilities of Property Owners
Installation & Maintenance: Property owners must install and maintain approved backflow prevention assemblies at service connections when a hazard or cross‑connection is present. The device must be appropriately sized, located for access, and installed in conformance with the city’s standards. The protective device must remain accessible for testing and maintenance and must not be submerged or obstructed.
Annual Testing: Each backflow prevention assembly must be tested at least once per year by a certified backflow prevention tester. Tests are also required at the time of installation, after repair, or if the device is relocated or modified. Upland sends notifications to property owners or contractors when backflow device testing is due, and test results must be submitted via the city’s designated backflow data management system.
Repairs & Replacements: If a backflow prevention assembly fails during testing, the property owner must promptly repair or replace it. After repair or replacement, the device must be retested by a certified tester and must pass before being returned to service.
3. Scenarios Requiring Backflow Prevention Assemblies (BPAs)
Irrigation or landscape systems that connect to potable water lines.
Fire protection or sprinkler systems that draw from the potable water supply.
Swimming pools, spas, or other water features potentially introducing non‑potable water.
Properties with auxiliary or alternate water sources (e.g. wells, cisterns, recycled water) that may cross‑connect to the potable system.
Commercial, industrial, or institutional facilities where processes or equipment may pose contamination hazards.
Any premises where the City or its inspectors determine that cross-connection risks exist and a protective device is necessary.
4. Testing & Maintenance Requirements
Certified Testers: Only certified testers (holding the required certification from San Bernardino County or other authorized certifying body) are allowed to perform the tests. Testers must maintain valid certification, use calibrated equipment, and adhere to approved testing standards.
Submission of Test Reports: Completed test reports must be submitted via Upland’s designated backflow data management system. The city issues notifications and reminders when device testing is due and expects timely submissions for compliance. Failure to submit or to complete required testing on time may result in penalties or enforcement action.
Repairs / Replacements: Devices that fail tests must be repaired or replaced immediately. Following repair or replacement, the device must be retested and pass before being put back into service.
5. Approved Devices & Certified Testers
Approved Devices: Only backflow prevention assemblies meeting recognized performance and design standards are permitted by Upland. The type of device (e.g. reduced pressure principle, double check, vacuum breaker, or air gap) must correspond to the assessed degree of hazard. Devices must be testable (except in limited allowed circumstances) and suitable for the application on the property.
Certified Testers: Testing and maintenance may only be conducted by individuals holding valid certification recognized by Upland’s program (such as the San Bernardino County Certificate of Competence). Testers must use properly calibrated equipment and follow accepted testing procedures. Only certified testers are authorized to submit the test results to Upland’s program.
6. Enforcement & Penalties
Non‑Compliance: Failure to install, test, maintain, or submit required reports for backflow prevention assemblies constitutes a violation of the City’s cross‑connection control program. The City may issue notices, require corrective action, or invoke enforcement measures for noncompliant properties.
Water Service Interruption & Restoration: Upland may discontinue water service to a property that does not comply with the backflow prevention requirements. Service will only be restored after installation, testing, repairs (if needed), and proper documentation are satisfactorily completed.
Penalties: Late submissions, failure to respond to notices, tampering with or bypassing backflow devices, or repeated violations may lead to additional penalties or fees. The City may withhold approvals for permits, water service connections, or final inspections until full compliance with the cross‑connection program is achieved.
