PROPERTIES WITH FIRE SPRINKLER SYSTEMS
Orange County Fire Authority has the authority to review meter downsizing requests for properties with fire sprinkler systems. Applicants with fire sprinklers should first contact one of the following OCFA Fire Safety Engineers to understand what is required for their particular property. Providing a name and property address will help expedite the process.

ADJUSTMENTS TO FIXED METER CHARGE
Fixed meter charges are assessed monthly according to meter size (flow capacity). If a water meter is replaced as part of this program, the adjusted fixed charge associated with the smaller meter size will be assessed retroactively to the beginning of the month in which the completed application is submitted to TCWD.  

Note: As approved by the Board of Directors at the December 19, 2024 Regular Board Meeting, any approved meter downsizing requests that were submitted to TCWD on or before February 17, 2025, the adjusted fixed charge will be assessed retroactively to July 1, 2023. Any applications received after February 17, 2025 are subject to the normal Program rules.

Any difference between the prior fixed charge and the adjusted fixed charge over the retroactive period will be credited to a customer’s monthly bill on the next billing cycle.
