“…In rural contexts, information about intermittent water sourcessuch as groundwater sources where access fluctuates seasonally or with precipitation eventsis generally spread by word-of-mouth. Sensors and mobile technology may present opportunities for notification systems that save residents time by steering them to the “best” available water source (e.g., cleanest, nearest, or fastest-flowing), but most of the sensor research for rural water systems has focused on water quality, usage patterns, or infrastructure maintenance. − …”

Water supply interruptions contribute to household water insecurity. Unpredictable interruptions may particularly exacerbate water insecurity, as uncertainty limits households' ability to optimize water collection and storage or to modify other coping behaviors. This study used regression models of survey data from 2873 households across 10 sites in 9 middle-income countries to assess whether water supply interruptions and the predictability of interruptions were related to composite indicators of stressful behaviors and emotional distress. More frequent water service interruptions were associated with more frequent emotional distress (β = 0.49, SE = 0.05, P < 0.001) and stressful behaviors (β = 0.39, SE = 0.06, P < 0.001). Among households that experienced interruptions, predictability mitigated these respective relationships by approximately 25 and 50%. Where the provision of continuous water supplies is challenged by climate change, population growth, and poor management, water service providers may be able to mitigate some psychosocial consequences of intermittency through scheduled intermittency and communication about water supply interruptions. Service providers unable to supply continuous water should optimize intermittent water delivery to reduce negative impacts on users, and global monitoring regimes should account for intermittency and predictability in post-2030 water service metrics to better reflect household water insecurity experiences.

Africa lags behind the world on operational and financial progress to maintain safe drinking water services. In rural Mali, we explore the implications of monthly flat fee contributions and volumetric (pay-as-you-fetch) payments for water use and revenue generation. By assessing 4413 months of data across 177 handpumps, we find that once payment modalities switch from volumetric payments to monthly flat fees, a waterpoint registers a more than three-times higher monthly revenue. While flat fees cover a higher share of the operational costs of providing reliable water services, a subsidy gap persists. Flat fees appear to stimulate daily water use which more than doubles compared to volumetric payments. We estimate that a 1 °C increase in average monthly temperature is associated with 180 more litres of water used every day per handpump, emphasising the importance of climate-resilient water supplies. Based on these insights, we discuss the role of professional service delivery models to support reliable drinking water services for rural communities.

This paper presents updated water handpump functionality estimates for eight councils in the Mvila Division, southern region of Cameroon. The methodological approach was based on a technical inspection of 647 water points (181 boreholes and 466 wells) and semi-structured interviews with 500 stakeholders, including 103 water point committee members, 389 water users, and 8 water experts. According to the findings, one out of every three hand pumps is inoperable. Based on this rate, approximately 1.3 billion CFA francs (approximately 2 million US dollars) invested by the government, communities, and development partners are immobilized and do not generate any benefit for affected rural communities. This high level of handpump non-functionality is due to the low economic viability of water point management, the poor functionality of water point committees, and the poorly structured handpump maintenance chain. The pooling of water point management at the scale of the Mvila Division appears to be an avenue to be explored to improve the functionality of the handpump.
