Restaurants

Serve customers water only upon request. If a customer does not want water, you save what is in the glass as well as the water it takes to wash it.
Don’t use running water to defrost food. Instead, try using the refrigerator, microwave or a filled sink.
Make sure dishwashers are full before they are used.
When using a conveyor belt as part of dishwashing, make sure that water isn’t running when nothing is on the belt.
Use dishwater run-off when running the garbage disposal to avoid using fresh water.
Try to use soft water for making ice to reduce the bleed-off that is necessary to make clear cubes.
Use ice flakes instead of ice cubes; they take less water to make.
Install high-efficiency aerators on all faucets.
