Bengaluru receives 1,850 MLD (million litres per day) of water from the Cauvery River. Out of this, a staggering 80 per cent (1,450 MLD) is converted into wastewater. Among the wastewater, 40 per cent flows through the Koramangala Challaghatta Valley, while 37 per cent flows to the Vrishabhavathi Valley, and the remaining portion goes to the Hebbal Nagawara valleys.
The BBMP cannot be faulted for the lack of foresight when it comes to solving the flooding issue, especially when it had planned a Rs 1,300-crore complete overhauling of the stormwater drain network in 2018.
