Brihanmumbai Municipal Company (BMC), Mumbai’s governing civic physique, will map the topography and assess the situation of the stormwater drainage system between the power water logging spot of Hindmata on BA Street in Dadar East and the Britannia pumping station. The examine will assist decide causes for continued waterlogging at Hindmata–Mumbai’s worse flood spot–even after BMC’s large drain augmentation work at and round this junction over the previous two years has been value over Rs 50 crore, officers mentioned.
Mapping the topography will decide if the drains are broken, have odd elevations stopping the free circulate of water, have utility cables, or are blocked with tree roots or crusted rubbish.
Together with this survey, BMC can be planning to construct extra drains round Hindmata in order that water from this elevated area doesn’t circulate downward towards BA Street, in line with a stormwater drains division official.
BMC in 2018 mentioned it undertook an identical survey to map drains round Hindmata. A civic official from the stormwater drains division mentioned, “This survey was executed solely in components and never your entire stretch as much as Britannia. We have to discover out the place the bottleneck is and why the water wouldn’t drain out even after the work BMC has carried out. Augmentation of the drain at and round Hindmata has diminished water receding time, however not prevented water logging fully.”
Since Hindmata is saucer-shaped, it used to obtain water from Parel, Lalbaug, and Dadar. BMC deliberate to intercept this water by way of augmented stormwater drains earlier than it reached Hindmata, and carry it to Britannia pumping station instantly. Earlier than the drain augmentation work, this water would circulate to Hindmata, and one pipeline on the junction carried water from three localities to Britannia pumping station.
BMC additionally augmented this pipeline to extend its capability to 50mm per hour from the present capability of 25mm per hour. It put in a field drain alongside 800 metres of BA Street from Hindmata.
Swapnaja Kishirsagar, assistant commissioner of the F/Southward with jurisdiction over Hindmata, mentioned, “About 10% work on the round drain round Hindmata is incomplete at Chinchpokli, which will be the bottleneck. Work was affected due to the unavailability of labour as a result of Covid-19 lockdown. Work on augmenting the 800-metre stretch of the drain on BA street is full.”
