After seven papers discussing specific examples of ecological sanitation projects, the workshop considered the background, motivation and feasibility of this technology. It was agreed that ecological sanitation could help tackle water scarcity, health protection and, by recycling water and nutrients into agriculture, food scarcity.

Key issues that remains are: the microbiological and chemical risks associated with the technology; the need for major information, education and support programmes; effective linking to reuse schemes; tailoring systems to meet local physical, socio-economic and cultural circumstances.
