Car Length: 16' (+7' space) = 23' in 40 Sec.
Rinse Flow Rate = 20 Gal/Min
Rinse On Time 28 Sec (16' Car Length)

Even though a car wash uses up to 100 gallons of water a minute to wash a car, it
actually uses only 20 gallons of fresh water a minute (9 gallons per car) — for the
same job that would require 50 gallons if done by a conscientous individual.
Re-use final rinse water as pre-final rinse or for the component prior to the final rinse.
Use carbon filtered water for a portion of the final rinse.
The final rinse water can be metered to show the city the minimum amount
required to rinse "washed" cam,
Employees and customers use restrooms wherever they are.

requirements of 3 to 30 employaes, 100 to 600 cars per day, and 2 people per car washed,
