Abstract

Handpump technology is documented as being the best option for the water supply of rural communities in the developing world. However, it has been observed that the amount of available handpump models significantly drops as water tables get deeper. Many handpumps are therefore expected to operate beyond their design specifications, which is responsible for many failures of handpump projects. This paper compares a total of 12 ultra deep-well handpumps (UDWHPs), with a pumping lift higher than 60 m, in terms of technologies, materials, outputs, costs and maintenance potentialities.

A comparative study between “Rope pumps” and conventional piston pumps on water quality and other sustainability parameters Appropriate technologies for rural water supply

In Tanzania there now are some 5000 Rope pumps both for small communities and Households. To compare Rope pumps with piston pumps like Afridev and Nira pumps regarding water quality, cost per capita and other aspects, the organisation ACRA effected a Comparative study. Some conclusions of the study are:
- Rural communities do not prefer piston pumps above Rope pump
-The water quality of tested Rope pumps is lower than Piston pumps but this is mainly due to bad installation. If installed right there is not much difference in water quality.

Publisher: Aquamor Pvt Ltd
Institution:

Several years ago Zimbabwe embarked on a program of upgrading family owned wells. This program was fully endorsed by the GOZ and operated under the MOHCW. The program has been well documented in papers and other publications. This program was based on the fact that for many decades individual families had chosen to upgrade their own wells privately and outside the formal GOZ rural water supply and sanitation program.

This manual provides detailed specifications and design drawings for the AFRIDEV handpump. The AFRIDEV Deep-well handpump is designed to lift water from depths of 10m to 45m. The AFRIDEV is suitable for boreholes with casing sizes of nominal 100mm, 115mm, 127mm or 150mm internal diameter (4", 4.5", 5" and 6").

The Specification results from work carried out by the UNDP-World Bank Water and Sanitation Program in partnership with handpump fieldworkers and development organisations in many countries.

Since the issue of the first AFRIDEV Specification in 1989, the AFRIDEV has become the deepwell VLOM handpump of choice in an increasing number of countries in Africa and Asia.

The Afridev Handpump is produced in several developing countries. The quality, however, varies from manufacturer to manufacturer. While most of the quality related problems can be attributed to lack of internal quality control mechanism at the factory level, others can be attributed either to inadequate procurement procedures or insufficient understanding of the quality assurance requirements by inspection agencies.
