From interlinking of rivers to interlinking of wells

Dear IWP

The sunrise story is linked with artificial recharge of groundwater through gravity. Some questions that come to my mind are;

  • Why does the water need to be shifted to another well, when it could be available readily and consumed from the neighbouring well?
  • Are the economics of pumping viable?
  • Is the quality of water identical from all the wells? Will it not have a clogging effect in due course of time?
  • Is there any scientific innovation involved?
  • Could the phenomena exist in alluvium formation also?

Story is interesting, however it may or may not be scientific. What do you think about it?
