When you cover large swarth of land with concert the rain water goes on the roof and on the road goes to gutter and makes it way to sevege. In absence, of this it is drawn underground and refills underground water.

When people were building these concert jungles, they didn't keep in mind where the water comes from and how exactly it's refilled and what we can do to replenish the capacity lost due to our development projects.
