This policy brief sets out key concepts, principles and practical implications for the citywide inclusive sanitation (CWIS) approach. Rapid urbanisation, ageing infrastructure, and climate change are exacerbating a sanitation crisis.
The focus of most urban sanitation interventions remains incremental expansion of centralised sewer infrastructure; little attention is paid to reaching the poor, long-term service provision, financial viability, or the public system functions required to achieve those outcomes. Meeting Sustainable Development Goal (SDG) targets requires a radical rethink of the urban sanitation sub-sector. CWIS offers this.
This paper presents a public services framework, set out by the Gates Foundation, for pursuing equitable, safe and sustained service outcomes, at city scale. It reviews the genesis and evolution of the CWIS framework and shares key principles and policy implications.
