When you wash your car on pavement, the rinse water runoff — along with all the chemicals it contains — can go to storm drains that empty directly into rivers and streams. This pollution has been proven to negatively impact aquatic life and ecosystems.
WaterSavers® car washes prevent water pollution by routing wash water to treatment prior to its return to the environment. These car washes also use only 40 gallons (151.5 liters) or less of fresh water per car wash - less than the typical home washing machine.
How WaterSavers® Works
To earn the WaterSavers® designation, a car wash must:
Water Quality Criteria
- Route all water discharge to a treatment facility or leech/septic field.
- Have a backflow prevention device installed and operable on the potable water supply.
- The car wash must meet all local effluent criteria.
Water Conservation Criteria
- For conveyorized or in-bay/roll-over washes, use an average of no more than 40 gallons (151.5 liters) 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 3 gallons (11.4 liters) 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).
In order to maintain our Wastersavers® status, we annually reaffirm with the International Car Wash Association that we meet the above criteria, including inspection by a licensed plumber or distributor member.
