I own 4 carwashes in AZ, all of which offer a "touch-free" automatic and a number of self service bays.

Water Reclamation is not required at S/S washes only Full Service(tunnels like Danny's).

The equipment to Recycle AND CLEAN your water cost in excess of $50,000 per wash and is used at few if any S/S washes. You are getting good water at these washes. The Spot Free rinse water has gone through an RO system like the stuff you would drink or buy yourself.

Now before anyone starts bashing car washes for the use of fresh water during a drought ask yourself how many gallons you use in your driveway when you wash your X.

You are using much more than if you were using a high pressure gun at my wash.

You are also spilling contaminants into the sewers and groundwater (Phoenix has drywells and retention areas)

These washes filter/seperate/pump this sludge and have it disposed of properly.

There's my 2 cents sorry if its TMI
