With the recent heavy downpours exposing its under preparedness in tackling the familiar problem of flooding, the BMC is mulling taking additional measures to improve the city's drainage system in the long-run.
And as part of this programme, it's now working on a plan to set up three mini pumping stations, two of them in the island city and one in eastern suburbs.
The mini stations are expected to come up at Dadar, Charni Road and Mankhurd to tackle area-specific/localized flooding.
Following the unprecedented inundation on July 26, 2005, BMC had been working on a project to set up eight pumping stations in a protracted manner. Of these, two—at Irla and Haji Ali—are now functional. And work on Cleaveland and Love Grove sites is underway, while that of Gazdhar Bandh and Britannia stations has just been undertaken. However, the construction on Mogra and Mahul sites still remain on paper.
"We are considering this idea to minimise reliance on major pumping stations. For instance, water accumulated at Hindmata and Hindu and Parsi colonies in Dadar is supposed to be pumped out by Britannia station (in Reay Road). However, given the distance (6km) between Hindmata and Britannia pump house, it'll be difficult to de-water the area concerned properly. Hence, we feel mini pumping stations will help solve such issues to a great extent, especially in the island city," Laxman Vhatkar, director of engineering service and projects, said.
Major stations have 6 to 10 pumps installed apiece. The smaller ones will have 2 to 4 pumps each installed in them.
"Each pump at the new stations will have the capacity to suck out 6 cubic meter (3,000 litres) of water per second. That equals 500 million litres of water per day. So, these stations, once they become operational, will bring big relief to residents," Vhatkar said. He, however, added that details like cost of the project and commissioning of the work were yet to be worked out.
