Four out of five people in rural Sub-Saharan Africa do not have access to safe drinking water. The international community made high-level commitments to secure access to safe drinking water for all by 2030 (Sustainable Development Goal 6.1). This ambition reflects the importance of safely managed water services for disrupting disease transmission in communities. In low-income, rural settings water is often accessed through hand-pumps or small piped water systems. While access to taps and handpumps has improved for many rural communities over the last few decades, the quality of the water being provided by this infrastructure is often not managed. And for most households, treating water themselves is not a reasonable option because of the costs and time requirement. Water treatment technologies that are designed for installation in decentralised water systems - either in the distribution system or at points of collection (community shared taps and handpumps) - can reduce the risk of diarrheal disease and improve public health outcomes. So far, research on supply-level rural water treatment has evaluated filtration and disinfection (chlorination, UVC radiation) methods, focusing on technological effectiveness. Beyond the technology development, however, there is a need for further research to understand how treatment interventions can be implemented broadly and sustainably. Particularly, key challenges related to supply chains, operation and maintenance, and financing must be addressed. 'Enabling Safe Rural Water Services in Kenya' is a solution-oriented research project that will bring together water, sanitation and hygiene (WASH) sector stakeholders to develop a new approach for implementing supply-level treatment in rural water systems. This approach will focus on enabling sustainable operation and maintenance of water services. Implementation of the approach will begin in two counties in Kenya and will expand under the direction of the Kenyan Water Services Regulatory Board. The purpose of this work is to systemically and sustainably improve drinking water safety in rural community and school settings in Kenya. It will generate learnings that can be adapted and applied more broadly to help advance universal access to safe drinking water in rural areas through supply-level treatment.

撒哈拉以南非洲五分之一的人中有四分之四无法获得安全的饮用水。国际社会做出了高级承诺，以确保到2030年获得所有人的安全饮用水（可持续发展目标6.1）。这种野心反映了安全管理的水服务对破坏社区疾病传播的重要性。在低收入中，通常可以通过手动泵或小型水系统进入农村环境。在过去的几十年中，许多农村社区的攻击和手泵的通道有所改善，但这种基础设施提供的水质量通常无法管理。对于大多数家庭而言，由于成本和时间的要求，对水本身进行治疗不是一个合理的选择。用于在分发水系统中安装的水处理技术 - 无论是在分配系统还是在收集点（社区共享的水龙头和手泵） - 可以降低腹泻病的风险并改善公共健康结果。到目前为止，供应水平的农村水处理研究已经评估了过滤和消毒（氯化，UVC辐射）方法，重点是技术有效性。但是，除了技术开发外，还需要进一步研究来了解如何在广泛，可持续地实施治疗干预措施。特别是，必须解决与供应链，操作和维护以及融资有关的关键挑战。肯尼亚的“启用安全的农村水服务”是一个面向解决方案的研究项目，它将召集水，卫生和卫生（WASH）部门利益相关者，以开发一种在农村水系统中实施供应水平治疗的新方法。这种方法将着重于实现可持续运营和维护水服务。该方法的实施将在肯尼亚的两个县开始，并将在肯尼亚水服务监管委员会的指导下进行扩展。这项工作的目的是在肯尼亚的农村社区和学校环境中有系统，可持续地改善饮用水安全。它将产生可以更广泛地适应和应用的学习，以帮助通过供应水平的治疗在农村地区获得安全的饮用水。
