Wells

We use drilled wells or boreholes to provide a school with a water point source through access to the groundwater. Throughout most of the Khwisero District the groundwater is shallow and contains sufficient water to allow a hand pump to pull the water to the surface. Generally, groundwater is a safer water source than surface water.

Schools where EWBMSU have drilled boreholes:
Ikomero 2008
Emwaniro, 2008
Ebuhonga, 2008
Shirali, 2005
Munyanza, 2006
Mwisena, 2009
Elwangale, 2010

Schools where EWBMSU had geophysical surveys performed but have not drilled a well:
Luanda AC
Mundaha
Emakuche
Mundoli
Eshinutsa
Emwiru
