How to submit a backflow test report to Monrovia-City, Water Dept.
Monrovia-City, Water Dept. is a public water system in Los Angeles County, California. Backflow preventer assemblies on its distribution system must be tested by a certified tester and the test report filed with the purveyor — here is how filing works.
How to file your backflow test report
Monrovia-City, Water Dept. takes backflow test submissions through BSI Online. Testers enter each test in the portal themselves — no bulk upload exists for any portal vendor — so BackflowGo preps your re-key sheet (every value in the portal's entry order) and routes you to BSI Online to file.
- One BSI account serves every BSI utility.
- Look up the property by its CCN (on the customer's notification letter — it never changes). Address search only works if you were the last tester of record, so record the CCN in the assembly's location notes.
- Enter each test, add to cart, then check out — unpaid reports aren't submitted.
The California form requirement
California does not mandate a single statewide test form. Most purveyors accept the standard USC/AWWA-style report, which BackflowGo generates — requirements live at the purveyor level.
