Building a Well
Phase I: Hydro-geologists survey the land to determine water level and quality. Permits and licenses must be obtained from the government. Then, equipment and personnel can be mobilized and the drilling site set-up.
Phase II: The borehole is drilled. Temporary casing must be installed to provide stability.
Phases III and IV: The borehole is drilled to the depth of the aquifer. The borehole must be lined with steel casing pipes to prevent the borehole from collapsing. Gravel packing is installed.
Phase V: After drilling, the borehole must be developed by air jetting, forcing high-pressure air and water down the borehole, until clean water emerges. A water analysis must be conducted to test the safety of the water. A well head slab is poured for the borehole.
Phase VI: A pump is installed inside the borehole to move the water upward. Solar panels are installed to power the pump. Solar power is more reliable than electric power in Kenya.
Phase VII: The control panel, electrodes, electrode cable, underground cables, and float switch, are installed.
Phase VIII : Water tanks are installed as reservoirs.
