The amount of water used to clean a car in an automatic car wash is determined by several factors, including whether the Car Wash is an in-bay service or a drive-through tunnel, whether the wash is a soft-touch wash or a touch-free wash, how many high-pressure applications are used, and how many additional services are selected.

A typical sit-down restaurant employs roughly 6,000 people. A tunnel car wash, on the other hand, can consume a lot more water than a drive-in-and-park in-bay vehicle wash.

Several cities around the United States, including San Antonio, Texas, have established comprehensive systems to cut water consumption during droughts.

Even in rainy Seattle, Seattle Public Utilities has given two commercial Car Washes conservation incentives to help them install water reclamation systems. And the craze is just getting more popular.

Water conservation technology is still the most effective technique for commercial vehicle washes to minimize the amount of wash water they use in a sustainable way.
