Village-level operation and maintenance (VLOM) is the use of a hand pump that requires minimal maintenance. It is sometimes referred to as VLOMM, or village-level operation and management of maintenance. During the UN decade on water boreholes, hand-dug wells and tubewells were constructed and water pumps provided to developing countries. Unfortunately this top down approach led to the installation of pumps that were difficult to maintain. VLOM pumps were introduced after the water decade, to allow remote villages to maintain pumps themselves and part of a larger strategy to reduce the dependency of villages on government and donor agencies.
