Water committees are believed to play an important role in managing community water systems in rural Africa. While past research suggests a relationship between water committee effectiveness and long-term sustainability of water systems, the relationship between committee activities and improved management outcomes is unclear. This study examines survey data from 124 communities in Northern Ghana. Two statistical models were developed to analyze the effect of water system management on water point functionality and user satisfaction with water service. Holding community meetings, practicing non-monetary resource mobilization, and preparing maintenance schedules were indicators of better management. Although existing research mostly focuses on pre-construction participation, these results highlight the role that water committees can play in engaging community members after construction is complete. Additionally, the supporting environmental factors of (a) access to tools and spare parts, (b) access to outside support, and (c) training were associated with improved outcomes.
