The civic body has proposed to increase the storage capacity of the two underground tanks at Hindmata, built to provide a catchment for floodwater. It is augmenting the two tanks, as the current capacity is not sufficient.

The two tanks were built at Pramod Mahajan Kala Park in Dadar West and St Xavier Ground in Parel last year. As per the initial plan, the Dadar tank was to have a capacity of 6 crore litres and Parel 4 crore litres, however, they were built to hold 1.62 crore litres and 1.05 crore litres of water, respectively. It spent Rs 130 crore on the construction of the two underground tanks and a rainwater pumping station under Hindmata flyover.
