Direct answer

What matters here

Due basis: Leander's hazard list sets frequency by hazard. The FAQ says annual testing applies to fire sprinkler systems, pools with auto-fillers, residences with septic using irrigation, and other listed hazards, while some residences without septic test every five years.

Highlights

Residential irrigation with septic requires annual RPZ testing.
Some residences without septic test every five years instead of annually.
Commercial irrigation is tracked through a separate City inspection program with a published qualified-inspector list.

Workflow

Determine whether the irrigation system falls into the annual or five-year residential lane.
If the property is commercial, check the separate commercial irrigation inspection program requirements.
Use the qualified tester or inspector list the City points to and submit through the BSI path when the backflow assembly is tested.

Residential

Leander is one of the best residential pilot cities because the FAQ explicitly distinguishes annual irrigation cases from five-year low-hazard residential cases.
Pools with auto-fill, fire sprinklers, septic-connected irrigation, and some private-well setups move a property out of the generic low-hazard bucket.

Commercial focus

Commercial and managed properties

Commercial sites should treat Leander as hazard-list driven rather than blanket annual-for-everything.
The City also runs a separate commercial irrigation inspection program with a published inspector list, which adds a second workflow next to the backflow assembly rules.
