Mumbai: The BMC will build a mini pumping station at Maharashtra Nagar subway in Mankhurd to address the issue of recurring flooding that occurs every monsoon before the next monsoon season. An underground storage tank will be constructed to collect accumulated water, which will then be discharged into Thane Creek through a 1,200 mm diameter pipeline. The project is estimated to cost Rs 14 crore. The proposal will be presented for approval in the standing committee on Wednesday.The Mankhurd subway is the lowest-lying point in Catchment Area 315. Since the natural slope of this depression is towards Thane Creek, rainwater begins accumulating at the subway even during light showers. As a result, east-west traffic is disrupted, causing significant inconvenience to commuters.To address the issue, the Storm Water Drains (SWD) department currently deploys every monsoon season three pumps with a capacity of 1,000 cubic metres per hour each and four pumps with a capacity of 240 cubic metres per hour each, and three pumps with a capacity of 250 cubic metres per hour each.However, this pumping arrangement has proved inadequate, and it takes considerable time to remove the accumulated water. To provide a long-term solution, the Assistant Commissioner of M-East Ward requested the establishment of a mini pumping station. Following this, engineers from various divisions of the SWD department conducted a site inspection to identify a solution. Based on the inspection, it was decided to construct a sump pit at the location, install high-capacity pumps within it and discharge the collected water into Thane Creek.
