Despite improved access to water supply systems globally, safe drinking water continues to limit progress towards Sustainable Development Goal 6.1. In particular, there is a disparity between access to uncontaminated water in rural and urban areas, with the former significantly lagging behind. In this discussion paper, researchers and practitioners in rural drinking water provision, management and regulation from Bangladesh, Kenya, England and Wales identify key aspects to advance regulation for rural drinking water services.

Global high-resolution drought indices for 1981–2022
Droughts are one of the most complex and devastating natural disasters and high-resolution data has proven essential in helping monitor their characteristics. This study has developed four high-resolution drought records based on the standardized precipitation evaporation index (SPEI) from 1981–2022. These datasets provide greater insight into drought patterns on varying scales, with potential benefits for the development of site-specific adaptation measures.
Assessing heavy metal contamination using biosensors and a multi-branch Integrated Catchment Model in the Awash River Basin, Ethiopia
The Awash River Basin in Ethiopia faces rising heavy metal concentrations due to poor wastewater management and loose enforcement of regulations around effluent discharge. Acute toxicity of surface and wastewater samples was measured using new molecular biosensor technology based on engineered luminescent bacteria. A multi-branch Integrated Catchment model (INCA) simulating tannery discharge under different treatment scenarios indicates that a 50% reduction in effluent concentrations could produce a 20 to 50% reduction in heavy metal concentration in the river over two years.
Story of Change: Turkana Jet research unlocks new understanding of East African droughts
The strength of the Turkana Jet – a wind feature which carries water vapour from the Indian Ocean across East Africa to Central Africa – is underestimated in current weather and climate models. New observations of the jet by researchers from the Kenya Met Department, the University of Nairobi and the University of Oxford have been used as a benchmark for UK Met Office forecasting models for East Africa.
Story of Change: Open source tools and skills for climate information flows
Reducing barriers to sharing and making use of climate information is vital for climate resilience. In Ethiopia’s Awash Basin, REACH partners have been working together to build tools to facilitate the use of climate data from weather and streamflow gauging stations. Weekly collaborative coding sessions form a long-term capacity building interaction.
Water chemistry poses health risks as reliance on groundwater increases: A systematic review of hydrogeochemistry research from Ethiopia and Kenya
This article systematically reviews groundwater chemistry results from 160 studies from Ethiopia and Kenya to evaluate potential health risks. The results indicate that chemical contaminants occur widely in groundwaters used for drinking but not regularly monitored: 78% of studies reported exceedance of contaminants that have direct health consequences, and 81% reported exceedance of aesthetic parameters. This demonstrates that universal and equitable access to safe drinking water will not be achieved without wider implementation of groundwater treatment.
Performances et perspectives des services d’eau potable en milieu rural en Afrique de l’Ouest francophone
Cette étude porte sur l’évolution des politiques d’approvisionnement en eau potable (AEP) en milieu rural en Afrique de l’Ouest francophone et sur les performances de la délégation des services d’eau en milieu rural. Dans de nombreux pays, il existe un fossé entre la théorie et la pratique, avec des modèles alternatifs de fourniture de services d’eau en milieu rural coexistant avec des arrangements informels, alors que les services auraient dû être délégués.
Performance and prospects of rural drinking water services in francophone West Africa
This study looks at the evolution of rural water supply policies in francophone West Africa and the performance of the delegation of rural water services. In many countries there is a gap between theory and practice, with alternative models for rural water services delivery co-existing with informal arrangements, where services should have been delegated.
Story of Change: Fit-for-purpose labs for monitoring and managing rural water supplies
In Nepal, Kenya and Bangladesh, researchers working with practitioners and local governments have established fit-for-purpose (FFP) laboratories to support reliable water quality monitoring and operational management of rural water systems
Results-based funding for safe drinking water services
This working paper presents an approach that advances contracts for results-based funding to incentivise delivery of safe drinking water services
