Understanding the relationship between groundwater chemistry and corrosion for rural water supplies
Open Report OR/26/057

Description:

Corrosion of handpumps has been a persistent problem in sub-Saharan Africa and has been documented for at least forty years. Corrosion can impact hand-pump functionality and contaminate water supplies. The rate and severity of corrosion is controlled by groundwater
chemistry as well as the type and quality of metal pump components.
The aim of this study, undertaken as part of the ‘Stop the Rot’ initiative, was to characterise the corrosivity of the groundwater chemistry and to predict the probability of corrosion and leaching of corrosion by-products into the groundwater, using existing data from the Hidden Crisis project. The Hidden Crisis project took place between 2016 and 2019 in Ethiopia, Malawi and Uganda and was an interdisciplinary project designed to examine the physical, technical and social determinants of hand-pumped borehole functionality across two surveys. Water samples were collected and analysed across both surveys.
