Lorentz Solar Pumps Keep the Water Flowing in Rural Villages
Cheaper and increasingly more powerful lorentz solar-powered water pumps are lifting more groundwater in locations where diesel use to reign. They are also helping agencies affliated to WASH to lifting villagers out of poverty. WASH agencies are now considering Lorentz Solar pumps as the solution for solar water pumping.

Our community health workers focus on assisting people in their last stage of life, making the need for spiritual support apparent.
John Dau Foundation Projects
The John Dau Foundation is fulfilling the dream of the former Lost Boy and genocide survivor John Dau to provide healthcare in the war-torn region of South Sudan by building and sustaining medical clinics and training community health workers.
Al Furqan - Maili Tisa Village Water pumping
The Community bore hole, which serves the local populace, and the centre has been re conditioned at the tune of over Kshs. 120,000.00. Thus providing clean water to the local populace.
The Milgis Trust's organisational structure ensures that conservation and development priorities are determined at the community level. The Trust Manager; Moses Lesoloyia, is responsible for ensuring that the Trust's activities are efficiently implemented and, in conjunction with the Management Committee, coordinates the development of the Trust'a role as an umbrella organisation for the ten administrative Locations in which it is currently working. Each Location has elected a Conservation Committee which is responsible for identifying and implementing their community's conservation and development priorities. The Security teams are employed by their respective Conservation Committees.
The Milgis Trust needs your support to sustain its success in this fragile ecosystem...

- Solar panels have no moving parts, and most have a warranty of at least 20 years
- Most solar pumps operate without the use of storage batteries
WindPumps vs. Solar Pumping
Wind pumps are the pioneering technology of water pumping. in the 1990s there were an estimated 30,000 wind pumps installed in Namibia. The technology has a well developed service infrastructure.
Wind pumps have a similar life span as solar pumps and are able to deliver water from depths of about
120m. Daily flows from depth greater than 50m are typically considerably less then 10m³ per day.
Although only basic technical skills are required, wind pumps are work-intensive to maintain. Typically a maintenance takes three days. One day alone is needed to pull the pump up and take it apart in order to know which type of cylinder is used. The variety is very large, so spare parts can- not be ordered in advance. A second day is needed to get the spares, a third to reassemble the pump. Maintenance of the rotor, e.g. exchange of blades, and of the gearbox is a dangerous job, as you have to climb and work on a 15m high tower.
Against that, a solar pump is easy and fast to main- tain. it can be pulled up in 30 minutes. A spare pump end or motor is replaced in 15 minutes. 20 minutes later you have lowered the pump back into the well and get it started again.
Solar pumps are less expensive than windmills, are easier to install, and provide a more consistent sup- ply of water. This is especially true in areas where wind may be seasonal and inconsistent.
