According to the August 2022 report of Niti Aayog, Urban Wastewater Scenario in India, estimated wastewater generation in India is approximately 39,604 Million Litres per Day (MLD) in the rural regions. However, urban centres generate 72,368 MLD wastewater and only 28 percent is treated. Another study suggests that daily faecal sludge generation in the country is 1.20 lakh tonnes.The advisory is divided into nine chapters on the need for drying of sludge to make it suitable for its reuse, popular sludge dewatering techniques, techniques for elimination of pathogenic micro-organisms from the sludge, and working principles of SGHD such as their operation and maintenance.The advisory is expected to assist in wide utilisation of biosolids in agricultural farms as a soil conditioner.Wastewater generationAccording to the August 2022 report of Niti Aayog, estimated wastewater generation in India is approximately 39,604 Million Litres per Day (MLD) in the rural regions.
