As per Census 2011, 51% of urban households in India are dependent on Onsite Sanitation Systems (OSS). Under the Swachh Bharat Mission, around 30 million more septic tanks/pits (OSS) will be constructed by the end of 2019, producing another 180 million litres of faecal sludge and septage (FSS) everyday. Due to lack of faecal sludge treatment facilities, the cesspool vehicles that empty the septic tanks/pits, discharge FSS either in open fields, drains or in water bodies. This results in the contamination of water sources like rivers, lakes and the ground water that ultimately leads to public health hazards. The treatment of FSS is, therefore, of paramount importance.
