Conveyor Systems
When retrofitting a conveyor system, consider the following:
••
Limit freshwater consumption to 40.0 gpv, as recommended by ICA’s WaterSavers
recognition program.
85
••
For conveyor systems that utilize frictionless washing, consider installing friction
washing components to use during the wash cycles.
••
If a reverse osmosis treatment system is installed for use with a water reclamation
system or to supply spot-free rinse water, capture reject water and reuse during
wash cycles.
••
Install check valves to prevent backflow wherever possible.
In-Bay Systems
When retrofitting in-bay systems, consider the following:
••
Limit freshwater consumption to 40.0 gpv, as recommended by ICA’s WaterSavers
recognition program.
86
••
For in-bay systems that utilize frictionless washing, consider installing friction
washing components to use during the wash cycles.
••
If a reverse osmosis treatment system is installed for use with a reclaim system
or to supply spot-free rinse water, capture reject water and reuse during wash
cycles.
••
Install check valves to prevent backflow wherever possible.
••
Install laser sensors to evaluate the length of the vehicle being washed and ad-
just the washing procedure to the specific length of the vehicle.
••
Limit water consumption during the rocker panel/undercarriage cycle to 12.0
gallons per cycle.
Self-Service Car Washes
When retrofitting self-service car washes, consider the following:
••
Limit nozzle flow rate to 3.0 gallons per minute (gpm), as recommended by ICA’s
WaterSavers recognition program.
87
••
Install check valves to prevent backflow wherever possible.
••
If towel ringers are installed, use a positive shut-off valve.
