The Evangelical Baptist Mission has a mission/farm in Timbuktu, Mali that
includes an orchard and a large vegetable garden. Mali, part of
Sub-Saharan Africa, receives very little rainfall, but does have useful
underground water in many places. But, the problem for project developers
is that few areas are electrified and using diesel pumps is both expensive and
limited to relatively shallow depths (due to the usual mechanical drive
arrangement). Mali, on the other hand, has very good wind resources.
In March, 1990 EBM installed a 10 kW Bergey wind-electric water pumping system on a 24 m (80 ft) Tilt-up tower and an 8-stage Grundfos submersible pump. The system has been in continuous operation since that time. The only maintenance required was the replacement of a relay in the pump controller in 1996. The photo above shows the wind turbine and one of the few green areas in Timbuktu. |
