Of all the rivers in India today, only Brahmaputra is in surplus, and will cease to be if the Three Gorges dams get underway upstream, in China. These are just some of the stats that Intach's water specialist Manu Bhatnagar jolts people with - into thinking seriously about the precious resource.

The state offers a six per cent rebate on property tax for a year if incorporates water harvesting techniques in the building.
