Currently, Siruthuli
is involved in cleaning, dredging and de-silting of
the Valankulam Tank
Sewage Details
Located
in the heart of the city, Valankulam is the main
arterial tank that recharges the ground water of
a sizeable area of the city. Valankulam used to
have the distinction of being a prime film shooting
locale and a sailing practice site for the INS Agrani's
Naval Officers. Over the years, serious encroachments
and blocking of the water inlet points into this
large water body has led to very rapid depletion
of underground water in a 20 Km radius of the city.

Out of a total of 166 acres, 27 acres
are encroached. Although it might seem that the encroachment
area is less, as a percentage of the total area of the
tank, the encroachments are all located at crucial water
entry points, thereby blocking the free flow of water
into the tank. Over a period of time, the slums have
almost occupied the centre of the tank bed area. Vested
interest in blocking the entry of water to prevent water
inundation of the huts during the monsoons is also a
reality
The toxic medical wastes and sewage
from the Government Hospital and certain private hospitals
are let into Valankulam. Additionally, spinach was cultivated
over large tracts on the tank bed. Recent clinical investigations
revealed a high count of E-coli bacteria present in
the spinach harvested from Valankulam. We have been
able to arrest the cultivation of spinach inside the
tank.
Siruthuli started
the de-silting and standardisaton of Valankulam on 10th
September 2003. As city garbage disposal into this
tank has been occurring over the years, garbage removal
activity has been added along with clearing the contaminated
spinach and silt. Percolation pits are also being made
to enhance ground water augmentation.
So far, 26,455 cubic meters of garbage
and debris have been removed from the Valankulam tank.
Percolation pits have been created where possible. Further
work is pending for clearance of all encroachments.
The clearance of encroachments is being done by the
Government. |
