The Maharashtra Pollution Control Board (MPCB) has given the Kalyan Dombivli Municipal Corporation (KDMC) 15 days to make its existing 30-MLD (million litres per day) Sewage Treatment Plant (STP) functional and has directed the corporation to immediately divert the untreated sewage discharged into Ulhas and Waldhuni rivers. The board has also warned the KDMC of stringent action including filing of case against the Municipal Commissioner as well as members of the standing committee and other officials, if they fail to comply with its direction.
According to the MPCB, of the total 200-MLD sewage generated from KDMC area, the corporation discharges 170-MLD domestic effluent without any treatment into Ulhas creek. The notice comes after senior MPCB officials conducted a surprise inspection of the existing STPs totalling 30-MLD at Adharwadi and Motagaon, Dombivli, in April and found them to be non-operational.
“The work on three new MLD STP has been stopped since long. Similarly, no steps are taken to provide other proposed STPs or on increasing the capacity of existing ones,” the notice stated. So the MPCB has directed the KDMC to submit a concrete proposal for providing a 127-MLD STP within 15 days.
Moreover, the MPCB has asked the KDMC to develop a new site to dump the 550-MT municipal solid waste generated from Kalyan-Dombivli each day. At present, this municipal solid waste is dumped without any treatment at Adharwadi site, which is unauthorised site in the Coastal Regulation Zone area, according to MPCB officials. The KDMC has been dumping at this unauthorised site despite the High Court order in April 2013 to develop a MSW treatment plant at Umbarde.
The KDMC officials said they are unaware of the notice, but are working on additional STPs and treatment plants for municipal solid waste.
According to Ashok Baile, hydraulic engineer, KDMC, the 30-MLD STP is still under maintenance, but work on two 40-MLD STPs are 85 per cent complete in Kalyan East and Dombivli areas.
“The 170-MLD sewage that find its way into the creek without being treated at STPs passes through septic tanks, at least in the new buildings. These tanks act as a sort of sewage treatment unit for the effluent before it is discharged into the creek,” he added.
Meanwhile, the Deputy Municipal Commissioner Suresh Pawar admitted that the practice of dumping untreated solid waste at Adharwadi continues, the corporation is in the process of issuing tenders to develop landfill sites with treatment facilities at Manda and Bharave areas, but there is no has taken placeprogress on the approved Umbarde site.
