A borehole is a vertical engineered structure used to access the water from a water table held within the cracks of a rock in the subsoil known as acquifers. The boreholes can be several hundred metres deep. A pump is often installed at the bottom to pump the water up to the surface. 7 motorized borehole systems are fully installed and functional. These include Petta, Kirewa, Okiya, Ragem and Fualwonga.
