Adelante Africa has started a project, with the support of Leaping frog publications U.K. to build homemade water tanks to harvest water from the roofs of homesteads. Each tank costs around 75 euros to build. People organise themselves into groups of neighbours. Each family in the group has to contribute something towards the cost of the tank, either money or their time. When the group is ready, Adelante Africa hires a lorry to drop off the raw materials at the homesteads. They are taught how to construct the tanks and then they build them cooperatively one by one. 26 tanks have already been constructed with another 104 planned.
