Commercial, multi-family, and city municipal facilities with vehicle wash equipment that uses potable water from Austin Water must submit an annual efficiency evaluation. A plumber licensed by the State of Texas must perform the evaluation. The due date is determined by the evaluation zone for the ZIP code for a facility’s physical address (see the list below to find your zone). Properties can complete the evaluation up to 90 days before its due date.

*Failure to provide either a passing evaluation form or a compliance plan by the due date will result in a $200.00 initial late fee plus the daily accrual of a $25.00 fine until the property comes into compliance.
