The water supplied is not sufficient to meet the demand. Any amount of RWH will not help unless we minimise the use of water. Human beings need to reduce water consumption
Rain water harvesting might solve the water issue in Bangalore but rainwater harvesting done now for name’s sake covers 44,000 houses out of some 18 lakh properties.
Yeah I agree with @ Pranab I have also read somewhere that the BWSSB needs 10 more years to supply Cauvery water and provide underground drainage facilities to these areas.
I do not think that it is a good ideas buying properties in the outskirt of Bangalore, especially in the newly added areas. half of Bangalore might have to be evacuated in 10 years due to water scarcity.
