The BMC aimed to install 100 auto-activated rainwater detection meters but has so far only installed 57 of them due to space crunch. Of these, 25 have been installed in south Mumbai, while the remaining are in the Western and the Eastern suburbs. The meters will face the test this monsoon, and if successful, the city will get its flood map. The BMC had decided to install 100 auto-activated rain waterlogging detection meters to detect flood levels at chronic spots in the city last year. At least 25 were installed last September, and only another 32 have been installed since.

New year, new spots

There are several areas where rain water accumulates. A few years ago the BMC surveyed flood spots and eventually took measures to tackle them. But every year, new spots emerge and the civic body needs actual data to tackle them.
