Amidst a lack of water in the Cauvery river basin that supplies drinking water to
the city, the Bangalore Water Supply and Sewerage Board (BWSSB) has
written to Cauvery Neeravari Nigam (CNN) asking it to “on a priority basis
reserve” adequate drinking water for the city from Kabini and Krishna Raja
Sagara (KRS) reservoirs for Bengaluru.
This comes in the backdrop of a looming threat of drinking water shortage in
the city, as Karnataka and Tamil Nadu are locked in a pitched battle to share
Cauvery river water. Presently, Bengaluru draws 1450 mld water every day
from Shiva reservoir at Malavalli for its drinking water needs, which will
increase by another 700 MLD from January 2024.
However, to ensure adequate drinking water supply to Bengaluru, with a
population of 12.8 million, BWSSB needs 1.6 tmcft of water every month till
December 2023.
