Can a citizen-science approach to collecting data assist the management of intermittent water supply in low-income and data-scarce settings?

Intermittent water supplies (IWS) can be both a public health threat and an expensive challenge to address for households, requiring reliance on either costly water storage solutions or alternative water supplies. Despite the fact that IWS are present all over the world, there remains a persistent lack of data on the operation and failures of urban water supply infrastructure in low-income countries. Local government and water utilities tend to be blamed for the poor management of the water supply, and yet there is no established method for reporting or measuring the continuity, reliability, or hours of supply of pipe water delivery. This makes it difficult for water utilities to estimate real economic losses or the investment needed to improve the water supply. Lack of evidence and data on the behaviour of IWS also impedes the development of tailored water management policies, leading to inefficient decision-making from the top down. This paper therefore proposes a method to address the knowledge and data gap on IWS in low-income settings, using citizen science coupled with mobile phone technology to collect data on IWS in a bottom-up approach. The approach was trialled in Kathmandu, Nepal and has since been adopted by the local water supply company.
