Beneath the earth

From childhood
I silently do ask myself a question,
How is this big hole called well, how is it dig
And I got my answer these, found myself inside of already made well

In this part of the world how difficult it is to get water in these sensons

Water found in this big hole.

Though the water is found, it's still not safe to use, it needs treatment.
The wicked politicians of this country uses these periods to win votes for themselves, making promises that won't be fulfilled.
