BBMP officials said that water flows through Hebbal valley to Kalkere and Rampura lakes. If there is 60mm of rain per hour in this valley, there is no problem, but the area gets waterlogged if there is more than 80mm rain. To address this, the narrow railway bridge near Hebbal valley should be widened.
