Faecal sludge is the slurry that contains both solid and liquid waste that accumulates in on site sanitation system (OSS) e.g. septic tanks. It is raw or partially digested slurry that results from the collection, Storage or treatment of combinations of excreta and black water, with or without grey water. This has three main components- scum, effluent and sludge. It has an offensive odour, appearance and contains significant levels of grease, grit, hair, debris and pathogenic microorganisms. In the current scenario, the construction and management of OSS are left largely to in effective local practices and there is lack of holistic faecal management practices. Faecal sludge management involves collection, treatment and proper disposal/ reuse. Efficient faecal sludge management include safe disposal of the treated faecal sludge. Once the biological mass is separated or removed, the treated water may undergo additional disinfection via chemical or physical processes. This final effluent can then be discharged or re-introduced back into a natural surface water body (steam, river or bay) andthe water is further treated to be used for horticulture flushing, cooling towers & other auxiliary purposes.
