Overview of Rules & Metering

The City requires metering for potable water service and maintenance of metering equipment at customer premises. Meter types, installation locations, and meter-reading access are governed by utility service regulations and departmental standards. Customers are responsible for protecting meters from damage and for notifying the utility about leaks, tampering, or inaccurate readings.

  • Meter installation and ownership generally remain with the City unless an alternative agreement is published.
  • Meter reading frequency, estimated billing rules, and meter testing procedures are set by the Utilities Department.
  • Backflow prevention and cross-connection control may be required for certain commercial and irrigation services.
Keep meter access clear year-round to avoid service interruptions.
