1. Scope & Authority
The water utility in Temecula enforces a Cross‑Connection Control / Backflow Prevention Program to protect the potable water system from contamination caused by backflow or cross‑connections. The program is grounded in California’s Title 17 regulatory framework (governing cross‑connection control) and local utility policy. The utility identifies where backflow protection is required, mandates installations, oversees testing and maintenance, and enforces compliance as a condition of water service.
2. Responsibilities of Property Owners
Installation & Maintenance: When Temecula or its water provider determines that a cross-connection hazard exists, the property owner must install and maintain an approved backflow prevention assembly at the service or internal plumbing location. The device must be sized, located, and installed so that it is accessible for inspection, testing, maintenance, and repair.
Annual Testing: Each backflow prevention device must be tested at least once per year by a certified backflow prevention tester authorized by the water provider. Tests are also required after installation, relocation, or repair. The property owner is responsible for scheduling the test and ensuring the device remains compliant.
Repairs & Replacements: If a backflow prevention assembly fails testing, the property owner must promptly repair or replace the device. After repair or replacement, the device must be retested and validated before being returned to service.
Recordkeeping & Report Submission: Certified testers must submit test reports and maintenance logs to the Temecula water authority in the format the utility specifies. Property owners should retain records of installations, tests, calibrations, and repairs for inspection by the utility upon request.
3. Scenarios Requiring Backflow Prevention Assemblies (BPAs)
Backflow prevention devices are required in any situation where a cross-connection or contamination risk exists. In Temecula, typical scenarios include irrigation or landscape systems attached to potable water, fire protection and sprinkler systems, commercial or industrial operations with process water or chemicals, properties with auxiliary water sources (wells, reclaimed water, cisterns), and internal plumbing configurations where contaminants could enter the potable system. The required device type (e.g. reduced pressure, double check, vacuum breaker, or air gap) is determined by the hazard classification.
4. Testing & Maintenance Requirements
Mandatory Testing Events: All backflow prevention assemblies must be tested at least once per year. Additional tests are required when a device is newly installed, relocated, repaired, or modified.
Certified Testers: Only individuals holding valid certification acceptable to the Temecula water utility are permitted to perform backflow testing. Testers must keep their certification current, use properly calibrated equipment, and follow standard test procedures.
Submission of Test Reports: Test reports must be submitted to the Temecula water authority in the prescribed format and timeframe. Failure to submit timely reports or conduct required testing may trigger enforcement or penalties.
Repairs / Replacements: Devices that fail must be repaired or replaced immediately by the property owner or qualified professional. After repair or replacement, the device must be retested until it passes and is returned to compliance.
5. Approved Devices & Certified Testers
Approved Devices: Only backflow prevention assemblies that meet recognized design and performance standards and that are acceptable to the Temecula water utility may be used. The type of device must match the evaluated degree of hazard. Devices are typically testable (unless a specific exemption applies) and suitable for the intended application.
Certified Testers: Testing and repair may only be carried out by individuals with valid, recognized certification approved by the water utility. Testers must maintain credentials, use calibrated test instruments, conduct tests per accepted protocols, and are the only parties authorized to submit valid test reports to the utility.
6. Enforcement & Penalties
Non‑Compliance: Failure to install, test, maintain, or properly report on required backflow prevention devices is considered a violation of the cross-connection control program. The utility may issue notices of noncompliance or require corrective actions.
Water Service Interruption & Restoration: Temecula’s water utility may discontinue water service to properties that fail to comply with backflow prevention requirements. Service will not be restored until all devices are installed, tested, repaired (if needed), and documented to the utility’s satisfaction.
Penalties: Additional penalties or fees may apply for late test report submissions, failure to respond to compliance notices, tampering with or bypassing protective devices, or repeated violations. The utility may withhold new service connections, limit approvals, or delay building or occupancy permits until full compliance under the backflow control program is achieved.
