Perspectives on Faecal Sludge Management


As part of the FSM4 Conference convening in Chennai, India on 19-23 February 2017, Avnar Sahni, Director of Global Citizen India, talks to Sasanka Velidandla, CEO CDD Society, and Stefan Reuter, Director BORDA.


Translating global learning to local implementation, BORDA global focus on the entire FSM value chain, from the capture of faecal sludge via improved toilets, to its storage, transport and treatment in bio-based localised Faecal Sludge Treatment Plants (FSTPs), and finally to its reuse as non-toxic fertilizer, water for irrigation, and biogas energy. This full-cycle approach, along with the capacity for local and regional service provision, enable BORDA and CDD Society to design and deliver community-adapted FSM infrastructure and services.
