Mumbai: After following the orders given by National Green Tribunal (NGT), Maharashtra Pollution Control Board (MPCB) has demanded a progress report from the municipal corporation for setting up sewage treatment plants along the Mithi River for controlling the pollution in the river.
Based on the orders of NGT, Municipal Corporation of Greater Mumbai (MCGM) has to construct the required number of sewage treatments plants along the Mithi River within the span of eight months.
An MPCB official said, “We have asked the municipal corporation for the progress report and they have told us that they would send us the report in two days. The number of sewage treatment plants along the river would depend on the quality of sewage water that would be assessed by MCGM.”
The figure recorded in April this year reveals that, Mithi River has the lowest water quality index at 31.5 units. According to the officials at MPCB, the Water Quality Index (WQI) below 38 is termed as heavily polluted. The figure shows that the WQI was below 38 since January 2015.
According to MPCB officials, the city has a total number of six to seven sewage treatment plants. With several illegal industries along the Mithi river adding up to the pollution of the river, MPCB has also issued closure notices to the industries after they conducted a survey on the total number of illegal industries along the Mithi river.
These illegal industries consist of polishing and garments industries which are situated along the Mithi River who dump their sewage into the banks of the river which ultimately adds to its pollution.
An MPCB official said, “We issued closure notices to 97 illegal industries along the Mithi River. We are yet to issue closure notices to few more illegal industries along Mithi river since many industries have cropped up again.”
