2. Geology and Topography in and around Bhuj
One cannot understand the water system of the city without understanding what is happening underground!
The general slope of the terrain is toward the north (from the hills towards Bhuj) whereas underground “water proof layer” slopes the other way around.

Bhuj is located on a “porous” sandstone which acts like a “sponge”. The surface rain waters flows towards Hamirsar and the other city lakes. It can then penetrate the ground and get “stored” in this enormous natural underground “tank”. The underground water could then be tapped through one of the 60 wells in the city.
The shale layer, below the sandstone, is water proof and makes sure that the water doesn't flow out of Bhuj Area underground.
All the “feeder dams”, in the upper part of the catchment, are directly in contact with the shale layer. The water doesn't go underground and is therefore a great surface water storage which can be used to “refill” Bhuj lakes when required.
Incredible , isn't it!?
But what happened to this system? Is it still working? Discover it here
Bhuj Information Center is built thanks to Bhuj citizens contributions.
