Water conservation programs in hotels across the country continue to expand as hotels try to reduce their water consumption by imparting behavioral changes on their guests. The Hilton Hotels “Green Program—Conserve to Preserve” helps hotels save water and money while practicing more efficient housekeeping and landscaping. Through the program, the hotels provide guests with cards to indicate how frequently they would like to have their sheets, towels, and linens dry-cleaned during their stay. Hilton installed low-gallons per flush toilets and high-pressure, lowwater showerheads to save on water costs. The program uses low-water washers and dryers that use 1 gal of water per pound of linen. The program saves more than 12 million gal of water per month, in addition to the $1.50 per occupied room per day the program saves the Hilton Hotels in water utility bills. Future conservation programs will to develop to include stricter monitoring practices on individual hotel rooms, where surcharges increase due to excessive water use within the room. Pilot water conservation projects involve hotel rooms in arid climates that will monitor individual hotel rooms. The restaurant industry is a major consumer of water resources and newly formed conservation programs address the issue. Southwest Florida Water Management District’s Water Program for Restaurant Outreach) helps restaurants lower operating costs and conserve water by making a few adjustments in service and appliances. The program focuses on practical ways that restaurants can reduce their water consumption. By serving water only at the customer’s request, a restaurant saves the equivalent of two glasses worth of water that it takes to wash the glass in a dishwasher. The program encourages the installation of low-flow spray valves, which use only 1.6 gpm compared to conventional models that use 3 to 6 gpm. The spray valves are responsible for more than 50% of the total water used in all dishwashing procedures and the installation of the new valves will save the restaurant more than $1,300 per year.
