Despite the increased attention international organizations now pay to water supply and sanitation, the overall water supply situation in many countries is still deplorable due to the often low sustainability of installed water supply systems. Since there is a continuing need to introduce appropriate technologies for water supply in developing countries, the reported successes of the rope pump development and application in Nicaragua led to an evaluation mission to assess the performance and potential of this technology. This resulting report details the findings of the specific objectives including: the technical functioning and performance; the materials used and manufacturing quality; comparison with other handpumps; success factors for introduction in Nicaragua; technical and financial sustainability; affordability; cost-effectiveness; acceptance; private sector involvement; and replication of private sector involvement in other countries. The major conclusion is that the rope pump has a great potential to be introduced in other countries as an option to the range of groundwater lifting technologies since it can be locally manufactured, marketed, and installed by the private sector; operation and maintenance requirements are low; and the relatively low level of investment makes the technology accessible for individual households and farmers (except for the poorer sections of society). The report recommends international promotion of this technology as well as the development of pump selection criteria, standardized designs, manufacturing processes and quality control procedures for the rope pump.
