Determining the effectiveness and mode of operation of Community Lead Total Sanitation (CLTS): The DEMO-CLTS study
The study’s overall goal is to improve the behavioral change strategies used to eliminate open defecation.
This study will reveal the effectiveness and mode of operation of the community-led total sanitation (CLTS) intervention to decrease the incidence of open defecation (OD). In particular, it will determine which elements of CLTS are highly efficient in decreasing OD, which elements have no effect, which hinder the decrease of OD, and which are the …

Diversion for safe sanitation: Flushable urine-diverting dry toilet with on-site wash water recycling embedded in a concept of transport logistics and treatment
The squatting “diversion toilet” includes integrated wash water recovery for hand washing and toilet cleaning. It separates undiluted urine, dry feces and wash water. The used water passes ultrafiltration and is recycled for the same purposes.
The Swiss Federal Institute of Aquatic Science and Technology (Eawag) and industrial design company EOOS develop a urine-diverting dry toilet with the additional feature of an integrated wash water recovery that allows for the comfort of hand washing and toilet cleaning. The squatting “diversion toilet” pan separates three streams: undiluted …

VUNA - Promoting sanitation and nutrient recovery through urine separation (Valorisation of urine nutrients in Africa)
This project developed a system to collect source-separated urine and process it into fertiliser. Collection logistics, treatment technologies, and social and economic assessments of nutrient recovery were some of the activities.
By recovering nutrients from urine in small decentralised reactors, VUNA wants to develop a dry sanitation system, which is affordable for the poor, produces a valuable fertilizer, promotes entrepreneurship and reduces pollution of water resources. In this collaborative project, the Swiss Federal Institute of Aquatic Science and Technology …
