Full Description

Dishwashing in the typical restaurant consumes over two-thirds of the water used in thatestablishment. Nearly one-half of the dishwashing water is dispensed through the pre-rinse sprayvalve used to prepare dishware for the commercial dishwasher. Most pre-rinse spray valves soldand installed in today's food service establishments are high-flow (3-gallons per minute andmore), inefficient valves. The market penetration of low-flow (1.6-gallons per minute and less),efficient valves has not generally been significant in California.The energy regulators and water industry combined their incentives to implement a direct installprogram focused at transforming the market for pre-rinse spray valves. Approximately 16,900efficient valves are being installed in California food service operations on a pilot basis throughthis program. The success of the program in terms of water and energy savings and cost-effectivenesswill ultimately lead to a larger retrofit program directed at replacing 75,000 of the100,000 installed valves in California.The total potential energy savings from retrofitting 75,000 pre-rinse valves in California is 34million therms per year, which would save food service operators an estimated $17 milliondollars in operating costs. The total annual water savings is estimated at 6.8 million ccf, or15,500 acre-feet (19 million cubic meters). Includes tables, figures, appendices.
