(video) A dipper well in use, 2019

A dipper well is a perpetual-flow sink often used in coffeehouses and ice cream shops to rinse utensils.[1] Ice cream scoops and other food-preparation utensils can be placed under the continuous stream in order to remove allergens and protect against bacterial growth.[2] Most dipper wells have a single spigot and can be adjusted for both hot and cold water use. As largely a commercial appliance, dipper well valves are typically kept at full flow during all serving hours.[3] Dipper wells have also been used as key components in pharmacological experimentation.[4]

Criticism

The dipper well has been criticized in the United States as wasteful since on average it pumps Шаблон:Convert of water an hour and is normally left running continuously.[1][3][5] Because its potential for water waste is counteracted by a potential for increased sanitation, most health regulations do not prohibit or mandate dipper wells. It was estimated in 1988 that a dipper well running 12 hours a day in a single business could use up to Шаблон:Convert of water yearly.[5] It was found that some establishments, however, left dipper wells running even while the business was closed.[1]

Starbucks Corporation, for example, was targeted in 2008 for wasting over Шаблон:Convert of water daily through use of dipper wells.[6] The company's health and safety regulations prohibited the immediate shut-off of Starbucks dipper wells in order to prevent the breeding of pathogens,[7] but meanwhile continued work towards environmentally friendly washing alternatives.[8][9]
