Huntington Park Backflow Testing, Installation & Repair

1. Scope & Authority

Huntington Park’s Water & Sewer Division supplies potable water to roughly 6,600 service connections and enforces a robust Cross-Connection Control Program under the authority of California Title 17 and the State Water Board's Cross-Connection Control Policy Handbook (CCCPH). As per the city code (§ 6‑5.304, Ordinance 441‑NS): Backflow prevention assemblies (BPAs) must be installed at service lines where hazards exist, such as auxiliary water sources or industrial processes. Water service must be discontinued if a required BPA is not installed, tested, maintained, or if a cross-connection is discovered. Service will only be restored once compliance is confirmed. Premises must remain open to inspection if required by the Water Department.

2. Responsibilities of Property Owners

Installation & Maintenance: Property owners must install and maintain BPAs per the degree of identified hazard. Annual Testing: Assemblies must be tested at least annually (or more often if deemed necessary by the Field Services Director) by a certified tester.

Approved Devices: Only assemblies meeting AWWA C506 standards and approved by USC’s FCCCHR are accepted. An official Certificate of Approval is required.

Service Interruptions: The Water Department may physically shut off water service (break the service line) until hazards are corrected. 3. Scenarios Requiring BPAs

A BPA must be installed at or immediately inside the building—or the property line—before any branch lines if any of the following conditions are met: Presence of an auxiliary water supply that may be unsafe or unapproved. Use or handling of industrial fluids or objectionable substances that pose hazards. Internal uncontrolled cross‑connections, complex plumbing, or restricted inspection access.

The required protective assembly depends on the hazard severity: Double Check Valve Assembly (DCVA) for non-health hazards. Reduced Pressure Principle (RP) device or air-gap separation for health hazards or uncontrolled cross-connections. 4. Testing & Reporting Requirements

Initial Testing: Required at installation, relocation, or repair of a BPA.

Annual Testing: Must be performed by a certified backflow prevention tester, either by manufacturer rep, city personnel, or approved tester.

Record Submission: Test results must be submitted to the Water Department—and service may be discontinued for non-compliance.

5. Approved Devices & Certified Testers

Approved Devices: Only those assemblies conforming to AWWA C506 and listed by the USC FCCCHR are allowed, with a valid certification of approval.

Certified Testers: Testing must be performed by individuals authorized by the Water Department or certified per city standards.

6. Enforcement & Penalties

Non‑Compliance: Removal, bypass, or lack of a required BPA, or the discovery of cross‑connections, triggers termination of water service until corrected.

Inspections: The City reserves the right to inspect customer systems and requires remedial action when hazards are found. Huntington Park Gardens Authority Contact Info: City of Huntington Park – Water & Sewer Division 1315 Valley Drive, Basement Level Huntington Park, CA 90254 Phone: (323) 584-6274
