Coronita Backflow Testing, Installation & Repair

1. Scope & Authority

The Riverside County Department of Environmental Health enforces a Cross‑Connection Control / Backflow Prevention Program to protect the potable water supply from contamination due to backflow or cross‑connections. This program is implemented in accordance with California's Title 17 regulations and local utility policies. The Department retains the authority to require backflow protection and enforce compliance as a condition of water service. 2. Responsibilities of Property Owners

Installation & Maintenance: Property owners must install and maintain approved backflow prevention assemblies when the Department determines a hazard exists. These devices must be properly sized, located, and installed to ensure accessibility for inspection, testing, and maintenance.

Annual Testing: Backflow prevention devices must be tested at least once per year by a certified backflow prevention tester. Testing is also required immediately after installation, relocation, or repair. Property owners are responsible for initiating tests and ensuring compliance. Repairs & Replacements: If a backflow prevention assembly fails the test, property owners must promptly repair or replace the device. After any repair or replacement, the device must be retested and pass before being returned to service. 3. Scenarios Requiring Backflow Prevention Assemblies (BPAs) Backflow prevention devices are required in various situations, including but not limited to: Irrigation or landscape systems connected to the potable water supply. Fire protection or sprinkler systems. Swimming pools, spas, or other water features. Properties with auxiliary water supplies (e.g., wells, cisterns, reclaimed water). Commercial, industrial, or institutional processes involving hazardous materials. The City classifies hazards and determines the required level of protection based on site conditions.

4. Testing & Maintenance Requirements

Mandatory Testing Events: All backflow prevention assemblies must undergo testing at least annually. Additional tests are required upon installation, relocation, or after repair/modification of the device. Certified Testers: Testing must be performed by individuals certified by recognized organizations acceptable to the Department. Testers must maintain their credentials, use properly calibrated equipment, and adhere to accepted testing procedures. Submission of Test Reports: Testers must submit completed test certificates to the Department as evidence of compliance. The Department retains records of tests and repairs for at least three years. Failure to submit results or perform required testing as scheduled can lead to enforcement actions. Repairs / Replacements: If a backflow device fails, property owners must repair or replace it immediately. After corrective work, the assembly must be retested and pass before being put back into service.

5. Approved Devices & Certified Testers

Approved Devices: The Department specifies acceptable backflow prevention devices suitable to the degree of hazard. Options include single check valves, double check assemblies, reduced pressure principle devices, and air gap separation. In higher hazard situations, reduced pressure assemblies or air gaps may be required.

Certified Testers: Testing and maintenance must be performed by certified backflow prevention assembly testers. Only those with valid certification are authorized to submit test certificates to the Department. Testers must maintain their credentials, operate calibrated equipment, and adhere to recognized testing methods. 6. Enforcement & Penalties

Non‑Compliance: If a property fails to install, test, maintain, or properly report on required backflow prevention devices, it constitutes a violation of the cross‑connection control program. The Department may issue written notice ordering compliance. Water Service Interruption & Restoration: The Department is authorized to discontinue water service to premises that do not comply with backflow requirements. Service will not be restored until all devices are properly installed, tested, repaired (if necessary), and documented to the Department's satisfaction.

Penalties: Additional penalties may be imposed for late submission of test reports, ignoring compliance notices, tampering with or bypassing backflow devices, or repeat infractions. The Department may also refuse new water service connections or building approvals until full compliance with the cross‑connection control program is achieved.
