There is provision of Cauvery water connection and yes rain water harvesting is available as far as I know. But it is better if you can check with the builder regarding the same.
As far as I know the project has got approval from BBMP and you can avail home loan from banks like Axis, LIC Housing Finance, State Bank of India and State Bank of Mysore.
