What to check for Liberty City

Irrigation is central to Liberty City WSC's public rule, but the annual requirement is tied to irrigation plus septic.

  • Due basis: Liberty City WSC says it uses VEPO for backflow test records, licensed BPAT testers submit reports to VEPO, and annual testing is required for properties that include both a septic system and an irrigation system connected to the corporation's water supply.
  • Notice or device clue: Look for the BPAT/tester registration context, Envirotrax record, service address, or assembly identifier.
  • Who is affected: Liberty City WSC customers with both septic and irrigation systems connected to the corporation's water supply and a reportable backflow assembly.
  • Acceptance rule: Report acceptance depends on the named portal and the utility-approved tester route; keep proof that the report was submitted.
  • Program phone: 903-984-0541
