- Have a backflow prevention device installed and operable on the potable water supply
Water Conservation Criteria
- For conveyorized or in-bay/roll-over washes, use an average of no more than 40 gallons of potable/fresh water per car
- Use spray nozzles with maximum water efficiency and inspect the nozzles annually
- For self-serve washes, maintain high-pressure wash nozzles and pump systems that use less than three gallons per minute
- Keep water-saving devices at original or improved specifications
- Re-use spot-free reverse osmosis concentrate ("reject") in the wash process (if such a system is installed)
Each participating car wash must annually reaffirm that it is meeting the above criteria, including inspection by a licensed plumber or distributor member.
