Community engagement in water and sanitation service delivery is key for ensuring project sustainability and accountability. This Topic Brief looks at community engagement approaches used by WSUP in three cities within the African Cities for the Future (ACF) programme: Antananarivo (Madagascar), Kumasi (Ghana) and Maputo (Mozambique). The specific focus is on ways to encourage community involvement in the design of water supply and sanitation projects, and ways in which local service providers can elicit input and feedback from people living in low-income communities.
