The renewing of the Dahisar and Oshiwara rivers is set to begin after the contractors finalize the project. Reportedly, the Brihanmumbai Municipal Corporation (BMC) Rs 1,000-crore project is expected to be completed in the next three years.
The BMC standing committee will approve the proposal of awarding contractors for the rejuvenation of the Dahisar and Oshiwara-Walbhut rivers.
The rejuvenation work comprises the construction of Sewage Treatment Plants (STPs) at the bank of both rivers and the laying of sewer and stormwater drain lines.
If sewer lines are not possible, there will be the construction of interceptors to prevent sewage discharge and the construction of access roads along the banks of rivers.
The rivers are polluted due to the slums and industries situated along the banks leading to the discharge of raw sewage in the rivers.
The National Green Tribunal last year had directed BMC to look into the matter and take necessary steps to rejuvenate the rivers.
BMC has finalised a joint venture of S K-S P Associates for Dahisar, while for Oshiwara, a joint venture of Shapoorji Pallonji-Konark will do the work.
Addressing the situation, a BMC stormwater drain department official said that the treated water would be discharged into rivers. Seven STPs will be constructed at different locations to treat 27 million litres of sewage daily. He further said that for 15 years, contractors would maintain these STPs.
The project had earlier been delayed and saw an increase in cost due to the COVID-19 pandemic.
