Well # 2 – Oldonyo Orasha Well of Narok South District – is located about 14 km south of Ewaso Nyiro shopping center off Maasai Mara Road. The site is on latitudes 01 15’ 25” South and longitudes 35 44’ 57” East on approximate elevation of 1867 meters above sea level.
Oldonyo Orasha Well was drilled to a depth of 220 meters. Steel casings were inserted to a depth of 220 meters. The well is producing 44 cubic meters per day. Water was struck at two levels during drilling, the first between 102-120 meters, the second at 152-164 meters and the main aquifer struck at 188-214 meters.
The construction of the well consists of 8” diameter casings with 6” steel plain and perforated casings following the design of the supervising hydrologist. The borehole was then properly developed, gravel packed and sealed to avoid any contamination from shallow aquifers. The well was fitted with a solar powered pump connected to a solar panel grid. A pump house was constructed to house the controls for the solar equipment and store the harnessed power. A 10,000 liter holding tank was placed on top of the pump house to allow for storage of the well water and create immediate access to the water for the women. In addition, a public bathroom and 3 toilets were built to provide proper sanitation measures and to keep the area around the wells clean and uncontaminated.
Oldonyo Orasha Well is also experiencing naturally occurring moderately high concentration of fluoride and nitrates which has been determined to be safe for human consumption. We will consider purchasing a second solar powered water purification system from Merlin Eco Solutions should additional testing raise concerns about the level of contaminates.
The well is targeted to benefit 3,500 people, 3,000 cows, 10,000 goats/sheep and 100 donkeys. A water trough has been constructed to provide water for the local livestock.
