MUMBAI: Only 36 percent of sewage generated by cities in the state is being treated while the rest appears to be flowing down the water bodies as it is, reveals the state's pre-budget economic survey presented in the state assembly on Thursday.
Also only 72.5% of the solid waste is being treated daily, the survey adds, pointing out that around 60 percent small, medium and large industrial units were in the red or orange zone which meant they were yet to fully adopt the green initiatives to become environmentally sustainable.
Sewage treatment is a wastewater treatment that removes contaminants from sewage to produce an effluent suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution. The solid waste consists of household solid waste, construction and demolition debris, industrial solid waste, drainage residue, and waste generated from residential and commercial complexes.
The solid waste generated in the State is being treated in 56 common treatment facilities centres provided either by Municipal Corporations or Municipal Councils and Cantonment Boards. "For the processing of solid waste 378 composting projects in 321 urban local bodies (ULBs), 89 vermicompost projects in 79 ULBs, 47 biogas projects in 30 ULBs, 19 refuse-derived fuel projects in 9 ULBs, and one Waste-to-Energy Plant with a capacity of 4MW are in operation," survey revealed.

During 2021-22 up to December, there were 1,12,750 industries under the purview of MPCB. Under the Common Effluent Treatment Plant (CETP) scheme, financial assistance has been provided to install pollution control equipment for the treatment and disposal of hazardous solid waste generated from small-scale industrial units. CETPs have been commissioned in 26 industrial areas covering 7,851 industries. However, out of nearly 1.13 lakh industries, over 67000 were under the red and orange zone. During 2020-21 average effluent quantity treated was about 1,402 lakh litres /day.
