New techniques used at three of the city's chronic flooding spots, Hindmata, Gandhi Market and Milan Subway, have yielded results this monsoon. Though similar amounts of water were pumped out into nullahs amid heavy rainfall at Hindmata and Gandhi Market—336 million litres and 375 million litres respectively—from June to September, the BMC had to spend Rs 155 crore to keep the former spot flood-free as opposed to Rs 20 crore—almost one-eight of the amount—to drain Gandhi Market.

This is due to the fact that the civic body had to construct three huge underground storage tanks in two open spaces in Hindmata because it could not increase the capacity of the existing man-made drainage system there. Flooding at Gandhi Market, on the other hand, could be resolved with a mini-pumping station with high-capacity pumps.
