All new or existing permanent commercial car wash facilities, which incorporate a pre-rinse cycle, shall be equipped with a permanent water recirculating system. The recirculating system shall recapture and recycle both pre-rinse and rinse cycle water.
Rinse cycles shall be 40 seconds or less per vehicle. This shall be accomplished by increasing conveyor speeds.
The volume of water discharged from each water nozzle in the rinse cycle shall not exceed three gallons per minute.
Additional measures to further reduce consumption shall be implemented wherever possible, such as reducing the number of water nozzles in the rinse cycle, using automatic flow control valves, and plugging all unnecessary outflows.
