Local detail

Property, device, and enforcement notes

Open the parts that match the property and system. These details stay subordinate to the fast workflow above.

Program and failure notes
  • Failure to report annual testing through BSI Online can escalate to water service termination.
  • Testing companies must submit reports within 48 hours or the customer can receive enforcement notification.
  • The CCN from the reminder or overdue letter is needed to access BSI records.
  • Devices or assemblies are tested upon installation and at least annually.
  • BSI sends official due and overdue notices.
  • Customer Confirmation Number access is needed for BSI record lookup.
Residential notes
  • Residential owners with high hazard connections or septic/outside-water-source conditions can receive BSI notice-driven annual requirements.
  • If a customer receives an overdue notice after testing, League City points them to BSI with the CCN to confirm whether results were submitted.
Commercial notes
  • Commercial high hazard sites are central to the program and carry owner responsibility for annual proof of compliance.
  • Testing companies must submit reports within 48 hours through BSI and need the customer's CCN from the reminder or overdue letter.
Irrigation

League City's high hazard list includes outside water sources and septic locations, so irrigation and outside-water contexts should be checked against the BSI annual record.

  • Septic system locations are named as high hazard examples.
  • Water connections from outside water sources are named as high hazard examples.
  • Annual BSI notice and CCN workflow controls the practical action.
Fire line

League City's page centers on high hazard devices and BSI reporting rather than a separate public fire-line section.

  • High hazard classification controls the strongest annual signal.
  • Repairs and replacements must be done by a licensed tester and permitted by the City.
  • BSI Online remains the accepted reporting path.
Cost and fee context

Private testing prices are market-based, but League City publishes a one-time $35 registration fee for each backflow device.

Repairs, replacements, and overhauls must be performed by a licensed tester and permitted by the City.

League City also publishes a $75 nonrefundable annual tester registration fee and a $40 processing fee risk when enforcement escalates.

Evidence ledger

Official sources

League City uses BSI for annual notices and electronic records, requires certified testers to submit reports online within 48 hours, and tells testers to obtain the CCN from the customer's reminder or overdue letter.

BackflowVerdict summarizes these records; the governing entity remains the authority.
