What Is Citywide Inclusive Sanitation and Why Is It Needed?

CWIS focuses on providing urban areas with access to and benefits from adequate and sustainable sanitation services, including the safe, effective, and sustainable management of all human waste along the whole sanitation service chain. This guidance note is part of a series that aims to share essential knowledge to embed CWIS principles in planning and delivering sanitation services to ADB developing member countries. These learning materials were prepared by ADB’s Water Sector Group and structured along the ADB project processing cycle.
