Monitoring is one of the key building blocks for an effective WASH system at RWIDF, which generates the information and feedback that facilitate adaptive change and well as planning and regulation… WASH systems thinking is the idea that drives RWIDF’s approach to the development, implementation, and sustainability of WASH services.The interplay and collective performance of all the factors that contribute to the effectiveness and sustainability of WASH servicesare at the heart of RWIDF’s understanding that the provision of these services happens in a complex system. For services to be provided and maintained, every actor and aspect of the system needs to function and to be effective and adaptable. Monitoring is one of the key building blocks for an effective WASH system. It refers to the processes of capturing, managing, and disseminating the information needed to effectively deliver WASH services at all levels. Monitoring generates the information and feedback that facilitate adaptive change as well as planning and regulation. Monitoring must be done systematically and must be reliable to be used as a basis for policy and investment decisions by different stakeholders in the sector. Information is typically collected from users and on infrastructure about the services being delivered to whom, when, how, and of what standard or quality. This could be in terms of functionality and reliability of water points, for example. Such data is vital for improving the routine management and delivery, as well as long-term planning, of services. Most important, monitoring data has to be analyzed and the results communicated to facilitate decision making at various levels. RWIDF in 2016 conducted a health clinics study to assess the impact of its work on improving health in the community. The results of the study informed RWIDF’s current Approach in WASH Project Implementation in South Western Uganda.
