A CORRESPONDENT mailbag@ mid- day. com THE Brihanmumbai Municipal Corporation ( BMC) in its budget has proposed exploring a new technology wherein gate pumps will be installed at the mouths of nullahs to minimise the tidal effect in the city during the monsoon.

These gate pumps at outfalls of stormwater drains ( SWD) will not just help discharge rainwater into the sea or creeks but will also stop the tidal water from entering the city during high tide.
