Looking for Water volume per car - average

[Kat]

Hi All
I’m trying to find out how much water is used roughly per car in the self serve bays for say a 10 minute wash?
Can anyone help me with this?
Also looking for the water volume per car wash for a Petit wash. Website says 43gallons per wash, just want to check this.
Thank you kindly

ICA published a poster and study years ago about water usage in different types of car washes. As I recall SS usage was around 17 gallons per car, the most efficient way of washing a car. I would check with the ICA, ( International Car Wash association}
