Handpumps are used primarily in developing nations as a manually powered means of bringing water to the surface from a borehole, rainwater tank or well.
The main types of hand pumps are the India Mark II, the India Mark III, and the Afridev deep-well (30 - 40 m deep) pumps.
Village Level Operation and Maintenance (VLOM) refers to low maintenance handpumps which can be maintained at a village level, intended to provide reliable long-term service.
