Centre for Science and Environment (CSE) has been actively working in faecal sludge and septage management (FSSM) in India by monitoring and evaluating the performance of FSTPs across the country. In this study, 16 treatment plants were evaluated in Odisha, a state actively involved in the sanitation sector, including FSSM, since the advent of Swachh Bharat Mission (SBM) in 2014. The study also involves the re-evaluation of 11 plants in the state with an aim to understand the long-term performance and sustainability. Evaluation of a STP co-treatment plant in Puri and an assessment of cocompost quality in Jatni were also part of the study.

Re-evaluation of the FSTPs showed both improvement as well as decline in the performance of the plants in terms of effluent and biosolids quality, as the results were compared with the national standards during both the study periods.
