Aquifer Mapping
project team was again on the quest for open wells. This time our project
partners ACWADAM also accompanied us for this search so that we could get a
perspective on geology too. The earlier maps as old as 1973 suggest certain
open well locations near the lakes. However, increased urbanization, heavy
pumping through borewell, conversion of lakes into constructed land has led to
drying up of these open wells. Thus, hardly you find people staying close by
knowing the existence of such open wells though they might be in use for
dumping their garbage.

The two wells that
we stumbled upon are near Doddakannelli kere. The Kere falls in survey number
109 with an area around 18 acres, 24 guntas. The lake is part of BBMP
jurisdiction. Currently the desiltation work is finished and lake is completely
dried up with expectation of getting filled during this monsoon. The lake
boundary is defined by fencing around the lake.

We also found three
borewells around the lake. Two of them were dried but one is still pumping
water. After a small chat with local person, we got to know that this pumping
borewell is a government borewell and pumped water is supplied to the
doddakannelli village. The borewell depth varies from 500ft-1000ft in this
area.

Sinking of shallow
wells is the most economical solution to construct a good water supply for
homesteads and communities and that is why lakes, river bank one can find fresh
ground water can be found within a depth of maximum 20 metres.

Details about the
two wells are as below:
two wells are as below:
- Well 1: It is smaller with
square upper structure to install pulley. The well is dry with garbage
dumped inside. - Well 2: The other well some
20-30 m from this well is bigger and circular with diameter of 8-10 m.
Inside, the diameter is not uniform i.e. the smallest diameter is at the
bottom the top has highest diameter. The well is dry and covered by all
sides with trees and hence we couldn’t find it initially.

According to the
local person we spoke to, these wells had water some 40 years back as he and
other people used to swim when they were kids. The real question now to ponder
on is how the water can be revived!
