Ensuring the quality of boreholes and pumps for rural water supplies

In sub-Saharan Africa, an estimated 200 million people (about one in five of the population) rely on a handpump as their main source of drinking water, using about 700,000 handpumps. While the popularity of other technologies is growing, handpumps are likely to remain important in the region for decades to come, particularly in areas that are remote or with low population density. Unfortunately, many handpump services perform poorly or fail prematurely due to technical or installation defects with the borehole or the pump, as well as weaknesses with operation and maintenance or financial constraints.

But many handpump sources are failing prematurely – most likely due to a technical, or installation problem with the borehole or pump. Rapid handpump corrosion is one cause of premature failure, as are faulty components, or low-quality boreholes. A broken, or failed handpump or borehole means that people have to revert to distant, or contaminated sources of drinking water.

Stop the Rot is an RWSN initiative which strives to raise the quality of handpumps for rural water supplies and mitigate rapid handpump corrosion. Since commencing in late October 2020, the initiative has brought stakeholders together with an interest in taking action to address these issues. The Stop the Rot Action Group meets 3 to 4 times per year (online).
