The world can no longer afford to sidestep the urgent need for safely managed sanitation services. Coupled with the very real threats of climate change effects and antimicrobial resistance, more than half the world's people who live in densely populated and emerging urban areas are facing a public and environmental health crisis. It is a matter of rights and survival.

Over the years, SNV and partners have seen too many faecal sludge and wastewater treatment technologies fall into disrepair. For those still up and running, many work in less-than-optimal levels. In spite of the numerous treatment technology manuals and process documentation available to the public, this is the sad reality. Noticeably, documentation of the real-life accounts of the very people behind the decision to select a specific technology, and of those involved in service operations and management is limited. 

This publication is the latest of SNV and ISF-UTS' growing contribution to learning and exchange in the urban sanitation sub-sector. It seeks to address a gap in available information. Compiling nine case studies from Asia and Africa, the publication presents real-life stories and practical experiences of people's engagements with several treatment technologies in the market. By making this type of information available to the larger public, SNV and ISF-UTS encourage decision-makers and investors exploring the range of treatment technologies to also consider how people, in diverse settings, interact with treatment technology options. 

The publication is also available in separate chapters for download and/or viewing.
