Small water service providers operating in informal markets across the Global South address critical gaps in public investments in the rural water sector. This study analyses the growth and operations of private desalination plants and distributing vendors in Khulna, Bangladesh, within the broader landscape of uncoordinated investments by government, donors and households. Household water choices and payment behaviour vary spatially and seasonally, with observable wealth differences in self-supply investments in rainwater tanks and tubewells. Monitoring and regulating informal private providers can improve sectoral coordination, increase efficiency of service delivery and unlock commercial finances against the backdrop of declining aid-based financing.

Improving the Reliability of Water Service Delivery in Rural Kenya through Professionalized Maintenance: A System Dynamics Perspective
This study applies system dynamics modeling to assess the potential impact of scaling up professionalized maintenance services on piped water systems in Kitui County, Kenya. The study results show that over a
10 year simulation, calibrated with 21 months of empirical data and based on a range of key assumptions, delivery of professionalized maintenance services across the county may increase countywide functionality rates from 54% to over 83%, leading to a 67% increase in water production.
Water policy, politics, and practice: The case of Kitui County, Kenya
This article uses an action-orientated knowledge framework to consider types of knowledge produced through rural water “policy experiments” in Kitui County, Kenya over the past 10 years. Actionable recommendations for the further development of county-level water policy include: 1) ensure local ownership of the policy-making process whilst enabling appropriate technical and legal support; 2) take long timeframes of institutional change into account in donor programming; and 3) establish water, sanitation and hygiene forums that bring diverse actors within the sector together to build cohesion, facilitate knowledge exchange, enable collaborative learning, and deliver action.
Equitable urban water security: beyond connections on premises
This study investigates to what extent urban water security is equitable in a small town in Northern Ethiopia with almost uniform access to piped water services. Development of a household water insecurity index considering issues of quality, quantity, and reliability, demonstrated high spatial variability in water security between households connected to the piped water system.
Intra-seasonal rainfall and piped water revenue variability in rural Africa
This study explores how rainfall patterns influence water usage and revenue from user payments in Ghana, Rwanda, and Uganda.
When Water Quality Crises Drive Change: A Comparative Analysis of the Policy Processes Behind Major Water Contamination Events
This paper explore the delayed policy response to the arsenic crisis in Bangladesh through comparison with water contamination crises in other contexts
Evaluation of System-Level, Passive Chlorination in Gravity-Fed Piped Water Systems in Rural Nepal
This article presents a nonrandomized evaluation of two passive chlorination technologies for system-level water treatment in use in western Nepal. Our findings suggest that whilst safe storage, service delivery models, and reliable supply chains are required, passive chlorination technologies have the potential to radically improve rural household access to safely managed water.
Observations of the Turkana Jet and the East African Dry Tropics
This article presents research from a field campaign in northwest Kenya on the Turkana Low Level jet, an intrinsic part of the African climate system and principle method of water vapor transport to the African interior from the Indian Ocean. Measured for the first time in 40 years, this dataset presents new evidence on the Turkana jet, and creates an opportunity to better understand regional dynamics in one of the most data-sparse regions in the world.
Incentivizing clean water collection during rainfall to reduce disease in rural sub-Saharan Africa with weather dependent pricing
This article proposes a new pricing mechanism for ‘water ATMs’, made possible with pre-payment and remote sensing, where prices adjust during rainy seasons to incentivise the continued use of clean water sources. The authors estimate cost per capita and cost per disability-adjusted life year averted, resulting in values which compare favourably with other water quality interventions.
Modular, adaptive, and decentralised water infrastructure: promises and perils for water justice
This review summarises emerging realities for water insecurity in an era of disruption, and new developments that the authors call modular, adaptive, and decentralised (MAD) water infrastructure. These decentralised models require a justice-oriented framework to unlock the promise of sustainable access to safe, reliable, affordable water supply for a more mobile, just, and resilient world.
