The Sustainable WASH Systems Learning Partnership undertook an organizational network analysis to study interactions across WASH sector actors in Kitui County, Kenya relating to information, skills, resources, and authority relationships. The study sought to identify the position of organizations in the network and understand network gaps, successes, challenges, and actors’ perspectives on possible solutions to achieve rural water sustainability. Twenty-five sector actors participated in the study, consisting of government entities, NGOs, water service providers, a development partner, an academic institution, a social enterprise, and a private sector company. The analysis revealed opportunities to improve coordination and alignment in Kitui County’s water sector. Findings will be used to support discussions among WASH actors regarding better coordination strategies within the sector.
