The final rinse on a vehicle must be with spot free water. To make this water, a Reverse Osmosis (RO) system removes the minerals and solids from the city water. Typically an RO system may reject up to several gallons of water to make 1 gallon of spot free water. The reject water is captured in a separate well tank, which is mixed with city water, repressurized and used in any phase of the wash cycle that requires fresh water. The recycling process is included in the Flow Diagram of the American Pride Water Management System.
