Village water supply is one of the leading rural development priorities in the developing countries. Programs for drilling boreholes and equipping them for water lifting have been implemented extensively during the past two decades. In order to achieve the goal set for village water supply programs + providing adequate quantities of drinking water + it is necessary to choose an appropriate method for water lifting from among the many types of equipment available, including manual, mechanized, and motorized systems. Available sources of renewable energy, essentially wind and solar energy, can be applied in the same way as human or animal power, or even diesel systems. The question, therefore, is whether to give preference to (a) methods that are low in capital investment and provide relatively poor performance, (b) those that require considerable capital investment and complex maintenance but provide high performance, or (c) those methods that require a moderate capital investment but whose operating costs are high. The present report was not intended to offer definitive answers to that question, but rather to provide assistance to decision makers + program sponsors and development program directors + who are not experts in village water supply. It shows that "renewable energy" systems (such as wind pumps, solar pumps, and wind turbine generator pumps) can be valuable components of village water supply systems, and that their inclusion is justifiable under specific circumstances. It also demonstrates the importance of both quality of service and economic considerations as selection criteria and offers the specific application of methodology used in Mali by the Mali Aqua Viva program as an illustration. The reader should not be surprised to find that this report, which could well interest leaders of all the developing countries, makes numerous references to the Sahel. Apart from the fact that the countries of the Sahel undoubtedly have greater reason to take an interest in village water supply programs, they also have the richest experience in that field. It is therefore possible to draw conclusions from the far reaching programs carried out in those countries.
