After many failed attempts, the Brihanmumbai Municipal Corporation (BMC) may have figured out a long-term solution to the perennial problem of waterlogging at Matunga, King’s Circle and Sion Circle.
The low-lying areas get waterlogged every time it rains, affecting traffic and residents.
Following a study of the drainage system, the civic body found that the rainwater from all three places accumulates at one spot, called the catchment, near Sion.
However, as the catchment, which is underground, is unable to hold large quantity of water, the discharge is slow, resulting in flooding.
During the study, the BMC also found that the carrying capacity of the drains was just 25mm an hour and it cannot be increased because of lack of space.
With this information in hand, civic officials have now decided to split the catchment. For instance, the water at Sion circle will be diverted to another one, thereby ensuring smooth flow of water into the sea.
The BMC plans to start the work once the rains end and complete it before the next monsoon, said civic officials.
SVR Srinivas, additional municipal commissioner, said, “The study is almost done and we are planning to divide the catchments so that the flow of water is better. There are various other plans that will be worked out on local level.”
The BMC will also focus on maintaining and repairing the drains and a new concept of catchment engineers will be introduced.
Apart from this, the civic body will be analysing chronic flooding spots and how to stop waterlogging in the city.
“The catchment engineers will be responsible for maintaining the roadside drains and assuring that the flow is smooth and proper desilting work is carried out before the monsoon,” said a civic official, who did not wish to be named, as he is not authorised to speak to the media.
Recently, BMC chief Ajoy Mehta had assured corporators that the civic body would come up with a long-term plan to solve the problem of waterlogging during the monsoon and completion of the Guzderbandh and Britannia pumping stations.
