Due to their great potential benefits, village water supply systems have been favorite development projects of government and international agencies for several decades. They make a revealing topic of study for appropriate technology advocates, as they represent one task for which small-scale technology has been widely promoted. A basic conclusion: a water supply or sanitation project that is imposed on a community, without community involvement in determining the need for and nature of the system, or without an effort to train some community members to do maintenance and repair, is very likely to fail.
