Utility: City of Leander Cross-Connection Control
Last verified: 2026-04-04
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
- Fire sprinkler systems, pools with auto-fillers, and septic-connected irrigation are annual.
- Some residences without septic fall to a five-year testing cycle.
- Replacing an old grandfathered DCVA removes the grandfather and requires an RPZ.
Workflow
Workflow
- Use the City's hazard examples and FAQ to classify the property.
- Schedule the test on the cadence tied to that hazard class.
- Route the report through the City's BSI-backed workflow and reevaluate the device type if replacement is needed.
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 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.
Tester routing
Use the governing authority's official tester list first, then only treat any sponsor placement as secondary routing.
