Access
to continuous water supply is key for improving health and
economic outcomes in rural areas of low- and middle-income countries,
but the factors associated with continuous water access in these areas
have not been well-characterized. We surveyed 4786 households for
evidence of technical, financial, institutional, social, and environmental
predictors of rural water service continuity (WSC), defined as the
percentage of the year that water is available from a source. Multiple
imputed fractional logistic regression models that account for the
survey design were used to assess operational risks to WSC for piped
supply, tube wells, boreholes, springs, dug wells, and surface water
for the rural populations of Bangladesh, Pakistan, Ethiopia, and Mozambique.
Multivariable regressions indicate that households using multiple
water sources were associated with lower WSC in Bangladesh, Pakistan,
and Mozambique. However, the possibility must be considered that households
may use more than one water source because services are intermittent.
Water scarcity and drought were largely unassociated with WSC, suggesting
that service interruptions may not be primarily due to physical water
resource constraints. Consistent findings across countries may have
broader relevance for meeting established targets for service availability
as well as human health.
