Highland Backflow Testing, Installation & Repair

1. Scope & Authority

The City of Highland (or its public water utility) enforces a Cross‑Connection Control / Backflow Prevention Program to guard its potable water system against contamination from backflow or cross‑connections. This program is grounded in the authority of California’s Code of Regulations, Title 17, as well as the city’s water system rules. The city requires that all backflow prevention devices used be from an approved list, ensures hazard assessments are conducted, and mandates testing, maintenance, and reporting to ensure continued safe water service. 2. Responsibilities of Property Owners

Installation & Maintenance: Property owners must install and maintain approved backflow prevention assemblies wherever a cross‑connection or hazard is identified on the premises. The devices must be properly sized and located to allow access for testing and maintenance. The installation must follow city standards, and the device should remain accessible, protected from damage or freezing, and not obstructed by structures or landscaping.

Annual Testing: All backflow prevention assemblies must be tested at least once each year by a certified backflow prevention tester. In addition, devices must be tested when initially installed, after repair, or if relocated or modified. Property owners are responsible for scheduling the test and ensuring results are forwarded to the Highland water department for compliance tracking. Repairs & Replacements: If any backflow prevention assembly fails during testing, the property owner must promptly repair or replace it. After repair or replacement, the device must be retested and must pass before being returned to service. 3. Scenarios Requiring Backflow Prevention Assemblies (BPAs) Backflow prevention assemblies are required in situations where a hazard to the potable water system may exist. These include irrigation systems tied to potable lines, fire protection or sprinkler systems, swimming pools and spas, properties with auxiliary or alternate water sources (such as wells or cisterns), commercial or industrial facilities with processes that pose contamination risk, and temporary service connections (for example, construction water lines or hydrant meter connections). The precise type of required device depends on the hazard classification assigned by the city’s cross-connection control program.

4. Testing & Maintenance Requirements

Annual Testing / Inspection: Every backflow prevention assembly must be tested at least annually by a certified tester. Testing is also required at the time of installation, any relocation, or after repairs or modifications. Certified Testers: Only individuals holding a valid certification recognized by the city or county (for example, certification issued by San Bernardino County Environmental Health Services) are permitted to perform tests and report results. Testers must maintain current certification, use properly calibrated test equipment, and adhere to approved test procedures. Test Report Submission & Fees: Completed test reports must be submitted to the Highland water department or cross-connection control office in the form and timeframe required by the city. The city may issue reminder notices to property owners when tests are due. Failure to submit test results or complete required testing may result in penalties or enforcement actions. Repairs / Replacements: If a device fails, the property owner must repair or replace it promptly. After repair or replacement, the device must be retested and must perform within acceptable standards before being returned to service.

5. Approved Devices & Certified Testers

Approved Devices: Only backflow prevention assemblies listed on Highland’s approved list of devices may be installed. The device must be appropriate to the hazard level present. Common acceptable types include reduced pressure (RP) assemblies, double check valve assemblies (DC), pressure vacuum breakers (PVB), or spill‑resistant vacuum breakers, depending on use. The device must be testable (except in limited permitted cases) and meet recognized performance standards.

Certified Testers / Qualification: Testing and repairs may only be done by certified testers recognized by the Highland or county program. These testers must maintain valid credentials, use properly calibrated equipment, follow standard protocols, and are the only parties allowed to submit test reports for compliance. 6. Enforcement & Penalties

Non‑Compliance: Failure by a property owner to install, test, maintain, or properly report on required backflow prevention assemblies constitutes a violation of the city’s cross-connection control program. The water utility or regulatory authority may issue violation notices, require corrective action, or escalate enforcement. Water Service Interruption & Restoration: Highland may discontinue water service to any property that does not remain in compliance with backflow prevention requirements. Service will not be restored until all required backflow devices are installed, tested, repaired if necessary, and properly documented.

Penalties: Additional penalties may result for late test submissions, ignoring notices, tampering with or bypassing backflow devices, or repeated violations. The city may deny new water service connections, building permits, or final approvals until full compliance is achieved under the cross-connection program.
