| Ice Machines and Garbage Disposals |
Ice machines
 Ice machines have many commercial uses, from restaurants to lodges, and can use significant amounts of water, depending on the type of machine and the desired type of ice. Ice machines are composed of the following components: a condensing unit used for cooling, an evaporator surface for ice formation, an ice harvester, an ice storage container, and, in some models, a dispenser. The type of condenser an ice machine uses will have the largest effect on water use. Two types of condensers are available: air-cooled and water-cooled.
Water-cooled machines use 10 times as much water as air-cooled machines and water rarely is recirculated. In comparing water- and aircooled compressors, the compressor horsepower at design conditions is invariably higher with air-cooled machines. However, operating costs frequently compare favorably during a full year. The desired quality and visual clarity of ice also will influence water consumption. Ice quality, machine cleaning and water efficiency all need to be balanced for optimum operation. |

Garbage Disposals
 Studies show that garbage disposals can waste a significant amount of water. It is recommended that their use be minimized or eliminated from kitchen operations. Many facilities use strainers or traps that employ a mesh screen to collect food waste for proper waste treatment. Another option is to install strainers in sinks, leaving the food matter in the sink for disposal in trash receptacles or composting units.
