Residential

  • Westminster is stronger than many Colorado utilities for residential angles because it explicitly includes domestic service in the same city program.
  • Residential demand still becomes real only when the city has determined that containment protection is required.
Commercial focus

Commercial and managed properties

  • Commercial value is solid because Westminster makes the service classes explicit and does not hide fire line and irrigation behind a separate standards manual alone.
  • The broad scope makes Westminster a good expansion utility even without a public tester directory.
