The 'Stop the Rot' initiative documents the scale and extent of rapid handpump corrosion and the use of poor-quality handpump components in sub-Saharan Africa and tries to bring about actions to address these problems. These two interlinked issues contribute to poor handpump performance, rapid handpump failure and poor water quality, all of which can ultimately lead to abandonment of the handpump sources, thus forcing users to return to contaminated or distant water supplies.

The third report reflects on the existing guidance on handpump quality assurance, collates examples of poor-quality components, and examines handpump supply chains through a case study of Zambia.
