Engineering Field Testing of Non-Sewered Sanitation Systems

Non-sewered sanitation systems (NSSS) treat human waste where it is generated, eliminating the need to transport it through sewers. They offer exciting opportunities for safely managed sanitation across the globe. Informed by the extensive experience of teams working in India, South Africa and Thailand, this book is intended as a practical resource to assist in the field testing of NSSS. It is a complex task to assess newly designed, sophisticated systems outside of the laboratory, in an environment that feels natural to users. From site selection to decommissioning, we share our insights gained from managing activities and tackling common engineering challenges to help the success of future practitioners.
