The minister on Friday said the government planned to collect rainwater from stormwater drains and use it for potable purposes after treatment. This project will cost the state exchequer Rs 2,000 crore, he said.

Naidu aims to collect 12 TMC of water through RWH.

As all the water allotted to the city from Cauvery would be exhausted, the rain water is the only easiest available alternative, he said.

“The collected water would be stored in some of the major lakes in the city after preliminary treatment and it would be treated once again before it is supplied to the city,” he said.

He said that BWSSB would disconnect connections to buildings that do not have RWH systems after May 27.

The Bangalore Water Supply and Sewerage Board is planning to conduct 60 such awareness programs in the city.

Water price hike inevitable

IT, BT and BWSSB Minister Katta Subramanya Naidu on Friday said the Board is incurring losses as water rates have not been hiked for the the past six years.

The hike is inevitable, the BWSSB will go for it after summer, the minister said.
