Dear Prashant, Take the map of India. Take a scale. Note also the inclination of the land. Find where Pugaikal is. using the scale measure the distance between Pugaikal and dharmapuri ( where the project it to be implemented) and from mettur to dharmapuri ( taking into consideration the inclination). Now you tell me, if you want to buid a tap in your house, will you build a storage tank above the roof level, or below the ground level?
