The system pulls water out of the washing machine and injects it with ozone. The ozone itself breaks into water and air, causing no environmental harm. The system uses less water, and because ozone works best in cool water, less energy is needed to heat the water. Typical dollar savings range from 20 to 40 percent. Much of the savings from a water conservation plan will come from upgrading bathroom fixtures.
Additional savings are possible through changes in other areas of a facility.
Chances are good that water is being wasted somewhere. Simply reviewing how a facility uses water is a start to keep money from going down the drain. When a business joins the WAVE program, it agrees to appoint a WAVE implementation manager, survey water use in all facilities, consider options to achieve efficiency and upgrade the facility with water-efficient devices. WAVE partners attempt to realize 90 percent of the projected reductions in water use within five years. The EPA also provides training workshops that give technical information to facility managers.
