Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.
The national biogas extension programme in Nepal has been carried out successfully by the biogas support partnership (BSP). Their homepage reflects and capitalizes their experience in small-scale anaerobic biogas digester dissemination and construction.
The main aim of the project was to avoid manual scavenging of excreta and to improve the sanitation situation at the Navsarjan Vocational Training Institute. The technical solution proposed was source separation (grey-/blackwater) and reuse. Greywater is separately treated and reused in the garden while the urine and faeces (blackwater) are directly introduced into a biogas plant. Digested sludge is dried on basic drying beds and used as compost for the garden. UDDT were also installed. The concept was implemented and evaluated for its social and cultural acceptability, sustainable and hygienic safety.

The Salem is a hilly surrounded District in Tamil Nadu State with a tropical climate and temperatures within 35 to 40°C (thus perfectly suited for biogas plant). Ramu owns a toilet linked biogas plant and the improvement of his family’s socio-economic circumstances has had an enormous impact on local thinking. Now the local inhabitants of that area realise the importance of hygiene and the ecological and environmental values, and the demand for toilet-linked biogas plants is increasing steeply.

This case study reports the development of an ecologically sound sanitation concept at the Adarsh Bidyaprasarak Sanstha's College of Arts & Commerce. In comprises separate urine collection and a DEWATS system for the treatment of black- and greywater consisting of a biogas settler, an anaerobic baffled reactor and an anaerobic filter, a horizontal flow constructed wetland and a polishing pond.

The project described aimed at avoiding manual scavenging of faecal products and at improving the sanitation situation at the Navsarjan Vocational Training Institute. Now greywater is separately treated and reused in the garden while the urine and faeces (blackwater) are directly introduced into a biogas plant. Digested sludge is dried on basic drying beds and used as compost for the garden. UDDTs were also installed. The concept was implemented and evaluated for its social and cultural acceptability, sustainable and hygienic safety.
