Abstract

The exploitation of groundwater by means of boreholes for supplying small user groups and rural communities with water has already been widely applied in certain parts of the world for several decades. In recent years this practice has spread all over the globe, and hundreds of thousands of boreholes have been drilled to tap low yielding aquifers. It is evident that such boreholes require pumps for lifting the water. In developing countries these are usually handpumps, but solar as well as other systems with submersible pumps are also used, depending upon the energy sources available and the financial means of the beneficiaries. The results presented in this paper originate mainly from the experience gained from handpump-equipped boreholes within the World Bank executed inter-regional UNDP-Handpumps Project (INT/81/026) 2/. Particular attention is paid to presenting quantitative data on the effect of corrosion on the water quality of wells in terms of iron concentration and other parameters. Furthermore, the corrosion attack on galvanized iron, the effect of biofilms on the corrosion rate, and the difference between internal and external corrosion of rising mains are shown [author abstract]
