Abstract
Introduction:Sub-Saharan Africa lags behind the rest of the world in expanding coverage to improved water sources, and high rates of failing hand pumps in the region are another major impediment of equitable access to a sustainable water supply. Previous studies have found that governance, the decision-making process through which water, sanitation, and hygiene committees (WASHCos) identify and resolve their own problems, is associated with hand pump functionality.
Methods: We conducted a cross-sectional study in two different districts in northern Mozambique using a mixed-methods approach to assess the association between governance, women's experience, and sustainability of rural hand pumps. Regression analyses were conducted to identify potential predictors of hand pump sustainability, as well as the categories of governance most strongly associated with sustainability. Governance was divided up into four main categories, which included responsiveness, finances, management, and accountability.
Results:Of the 143 total hand pumps assessed, 90 (63%) of them were functioning on the day of the survey. The different models measuring the association between past and current functionality with individual components of governance identified varying predictors of functionality. Overlapping components included perceived water quality (p=0.003) and WASHCo rules and regulations (p=0.04). Finances and responsiveness were found to be most strongly associated with current functionality (p=0.001); however, when controlling for all other covariates, only responsiveness was significant. Those communities with at least one functioning water point had a higher mean score (79.9) for positive women's experience score than those no functioning water points (62.7) (p=0008).
Discussion:As our models produced varying results, it is difficult to conclusively identify any specific components of governance associated with sustainability. This differed from previous CARE studies that did not control for external factors such as community location or type of pump.
