Backflow Prevention Testing in Los Angeles Metro
California's backflow testing regulation transitioned in July 2024 — CCR Title 17 §7583-§7605 was replaced by the California Cross-Connection Control Policy Handbook (CCCPH) §3.3.3(b), shifting enforcement authority to each city's water purveyor across the Los Angeles metro's 8 jurisdictions. Every jurisdiction operates under CCCPH now, but local water purveyor programs vary significantly in reporting methods, enforcement timelines, and how aggressively they exercise service shutoff authority. The metro includes municipal water utilities like LADWP (serving the City of Los Angeles), smaller independent utilities in Glendale and Burbank, and retail purveyors drawing from Metropolitan Water District of Southern California's regional supply.
Purveyor enforcement across the metro
- LADWP issues the most aggressive enforcement, with service disconnection notices beginning 30 days after a missed annual test deadline.
- El Segundo water division maintains the lowest penalty structure, issuing courtesy reminders for 90 days before formal enforcement begins.
- Glendale Water & Power requires all certified testers to register with the utility before submitting any test reports within city boundaries.
- Burbank Water & Power operates a dedicated online portal for digital report submission, while Long Beach Water Department accepts mailed paper forms and emailed PDFs.
Fire sprinkler backflow assemblies (DCDA, RPDA) create a dual-obligation gap across all 8 jurisdictions — NFPA 25 §13.7.2.1 requires annual testing for fire system integrity, but CCCPH §3.3.3(b) separately requires annual testing reported to the water purveyor for drinking water protection. Many buildings test under NFPA 25 to satisfy fire department requirements but never submit reports to their water purveyor, leaving them non-compliant and exposed to service shutoff.
Building owners with properties across multiple Los Angeles metro cities answer to different water purveyors with different deadlines, different reporting systems, and different enforcement speeds — tracking compliance by purveyor jurisdiction, not city boundaries, prevents costly violations and service interruptions.

Burbank
Burbank authorizes service disconnection for backflow testing noncompliance under BWP CCCPH §3.3.3(b).
Burbank Water and Power (BWP), a municipal electric and water utility serving 46,000 connections, requires annual testing of all backflow prevention assemblies under CCCPH §3.3.3(b), the statewide standard that replaced CCR Title 17 §7605 effective July 1, 2024. BWP administers the cross-connection control program through its Water Service Division and tracks compliance through The Compliance Engine (TCE) portal.
Enforcement & service shutoff
- BWP issues a late-test notice after the annual deadline passes; buildings with untested assemblies enter non-compliance status immediately
- Service disconnection authority sits with BWP under Burbank Municipal Code Chapter 4.27 (Water Service) and BWP Regulations
- Failed assemblies trigger a 10-day repair deadline from the date BWP receives the failed test report; unremediated failures escalate to shutoff authorization
- Administrative citations under BMC §1- escalate from $100 first violation to $200 second violation to $500 per day for ongoing non-compliance
- Standard reconnection fees apply once BWP disconnects service for testing or repair non-compliance
Fire sprinkler backflow assemblies—typically double-check detector assemblies (DCDA) or reduced pressure detector assemblies (RPDA)—carry dual compliance obligations that many buildings miss. NFPA 25 §13.7.2.1 requires annual testing of these assemblies as part of the fire sprinkler inspection and test (ITM) cycle, but building owners must also submit those same test results to BWP under CCCPH §3.3.3(b). Battalion Chief Jim Moye at Burbank Fire Department may verify backflow records during the annual Title 19 fire inspection for sprinkler-protected buildings, but BWP holds enforcement authority and service shutoff power for unreported tests.
How Burbank differs from neighbors
BWP operates as one of four Los Angeles County water purveyors requiring submissions through The Compliance Engine (TCE), the online reporting platform that replaced paper mail-in forms. Glendale Water & Power and Pasadena Water & Power also use TCE, while most neighboring jurisdictions still accept direct paper or email submissions. BWP follows the CCCPH annual testing floor with no published local amendments that exceed state minimums—Burbank Municipal Code Chapter 4.27 delegates cross-connection program authority to BWP but does not add testing frequencies or assembly requirements beyond CCCPH §3.3.3(b).
Development pipeline
Warner Bros. Studio (110 acres, 36 soundstages) and Walt Disney Studios dominate Burbank's commercial building stock, with each campus operating dozens of backflow assemblies on process water, fire sprinkler, and irrigation connections. Hollywood Burbank Airport and the Empire Center retail development (1.2 million square feet) add concentrated assembly counts in the city's northwest quadrant. Studio expansions and soundstage construction drive steady demand for new backflow installations and certified tester capacity.
Submission & reporting
Certified testers submit all test reports to BWP through The Compliance Engine portal—no paper forms, email, or fax submissions accepted. Testers register for TCE access through the platform's credential verification workflow, then upload reports directly to BWP's compliance dashboard. Building owners who miss the annual deadline receive late-test notices through TCE, which tracks individual assembly due dates and sends automated reminders before non-compliance triggers shutoff escalation.
