1. Scope & Authority
The City of Simi Valley / Ventura County Waterworks District No. 8 enforces backflow prevention and cross-connection control to safeguard the potable water system from contamination.
This program is required under state law (including the California Environmental Protection Agency and State Water Resources Control Board) and the new Cross-Connection Control Policy Handbook (CCCPH) that took effect July 1, 2024.
The district has contracted with BSI Online to manage notifications, data submission, and reporting for backflow testing in the region.
2. Responsibilities of Property Owners
Installation & Maintenance: Property owners must install, maintain, and ensure correct operation of approved backflow prevention assemblies (BPAs) at their own expense if there is a recognized cross-connection hazard.
Annual Testing: All BPAs must be tested at least once per year by a licensed / certified backflow tester.
If a BPA fails, the owner must arrange to have it repaired or replaced and then retested.
Repairs & Replacements: Testers must submit test results via BSI Online, using the Customer Confirmation Number (CCN) given in notification letters.
Annual notifications are mailed to customers when tests are due.
If a property is out of compliance, the district may have the BPA tested and charge the property owner for the work and may impose penalties or service disconnection.
3. Scenarios Requiring Backflow Prevention Assemblies (BPAs)
BPAs are required in Simi Valley when a recognized cross-connection or hazard exists, including but not necessarily limited to:
Irrigation systems (especially those using chemicals or pumps)
Fire protection / sprinkler systems
Auxiliary / alternate water sources (e.g. wells, cisterns, recycled water)
Commercial, industrial, or institutional facilities with processes that pose contamination risk
New or replacement BPAs must be registered and tested within 48 hours of service activation, and thereafter at least annually.
4. Testing & Maintenance Requirements

Test Report Submission & Fees: Test reports must be submitted via BSI Online using the CCN.
Fees or administrative costs may be billed along with utility bills or in accordance with district policy.
Repairs & Retesting: If a device fails, immediate repair or replacement is required, followed by retesting to confirm compliance.
5. Approved Devices & Certified Testers
Approved Devices: Backflow prevention assemblies must meet recognized standards. The district requires that new or replacement BPAs be registered and tested by American Water Works Association (AWWA) certified BPA testers.
Certified Testers: Testers must be licensed / certified in accordance with district / state program rules. They must use the CCN to file test reports via BSI Online on behalf of the property.
6. Enforcement & Penalties
Non-Compliance: If property owners fail to test, repair, or maintain their BPA, or fail to submit reports, the district has authority to enforce compliance.
