What to check for Leander

Leander's irrigation rules are strong enough to justify a dedicated page. Residential irrigation can be annual or five-year depending on septic and hazard conditions, while commercial irrigation also carries a separate inspection program.

  • Who is affected: Commercial sites with listed hazards, fire sprinkler systems, pools with auto-fillers, and irrigation systems, especially where septic affects the hazard class.

Workflow

Leander workflow order

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