Understanding handpump sustainability: Determinants of rural water source functionality in the Greater Afram Plains region of Ghana

Handpumps supply water to tens of millions in rural sub-Saharan Africa. One third of these are nonfunctional at any time, limiting access and leading to use of less safe sources. In Water Resources Research, we analyzed data from 1,509 handpumps in Ghana’s Afram Plains using logistic regression and a Bayesian network; management, savings, and access to tools and parts were key predictors of functionality, and interacted synergistically. Addressing such factors may enhance functionality in this setting and elsewhere. The interactions and impacts of these management factors have not been reported previously.
