Dipper well

Criticism

The dipper well has been criticized in the United States as wasteful since on average it pumps 30 to of water an hour and is normally left running continuously. 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 260,000 USgal of water yearly. It was found that some establishments, however, left dipper wells running even while the business was closed.

Starbucks Corporation, for example, was targeted in 2008 for wasting over 6 e6USgal of water daily through use of dipper wells. The company's health and safety regulations prohibited the immediate shut-off of Starbucks dipper wells in order to prevent the breeding of pathogens, but meanwhile continued work towards environmentally friendly washing alternatives.
