NSS LANDSCAPE ASSESSMENT

Mapping the future of Non-Sewered Sanitation Systems

The NSS Landscape Assessment initiative focuses on identifying and addressing data gaps in non-sewered sanitation systems across Sub-Saharan Africa. These systems are essential for millions of people but are often hindered by fragmented data and poor integration.

Through extensive stakeholder engagement and field assessments across eight countries—including Kenya, Nigeria, Zambia, and Uganda—WSH Data Labs has mapped data flows, identified challenges, and co-developed solutions with utilities, municipalities, and regulators. This work provides a roadmap for strengthening sanitation data systems and improving service delivery.
