During the severe
drought in 2004 i.e. upto October 2004, since all the sources supplying water to
the Chennai City were dry and there was no water received from Kandaleru under
the Telugu Ganga Project, about 100 MLD of water was transported from the
distant sources like Gummidipoondi, Minjur, Tamaraipakkam, Periyapalayam,
Poonamallee, Mamandur-Palur, Thiruporur, Karunguzhi etc. covering a distance of
about 120 to 150 km. and the total quantity transported was 23,439.79 ML during
the period from 27.6.2003 to 9.11.2004. The
water supply to Chennai City was maintained through the mobile tankers by way of
filling 14,602 No. of stationary tanks and about 8,000 street supplies daily by
making about 13,000 No. of trips daily for internal distribution throughout the
city covering 15,089 streets. The
Government undertook this massive and onerous task of distribution through the
Chennai Metropolitan Water Supply and Sewerage Board at a cost of
Rs.196.69 crore during the year 2004 - 2005.
In the catchment
area of the main city water supply sources viz. Poondi, Cholavaram and Redhills
the rainfall during the year 2004 was 1171 mm against the normal rainfall
of 1400mm. The storage of water available in the main surface sources of Chennai
City viz. Poondi, Cholavaram and Redhills as on 1.01.2005 was 1,859 Mcft against
the total capacity of 7,412 Mcft. On
the same day last year, i.e. in 2004, the storage was only 272 Mcft.
In Chembarambakkam Tank which is a supplementary source to Chennai City
water supply, the storage as on 1.1.2005 was 405 Mcft against the capacity of
3,645 Mcft.
Consequent of improvements
in the water level, after the
rainfall during Oct. - Dec. 2004 the
ground water from the Well Fields
was extracted upto 95 ML per day.
7.
With the water available in the surface sources and receipt of water from
Kandaleru Reservoir under the Telugu Ganga Project and also water received from
the New Veeranam Project, the city
water supply is maintained at an average of 600 ML on alternate days, besides 60 ML being supplied to the Manali Industries
and Bulk consumers daily.
Water is received by consumers through the pipeline covering aboyt 89% of
the city area. Further, for the
streets where water is not reaching through
the pipeline due to the alternate day water supply, mobile water supply
is also being organised through
2,650 lorry trips (each of 9 KL) by filling 5,000 No. of
stationary tanks apart from 1,100 trips for
street supply .The storage in the lakes
supplying water to the city and the receipt from the Kandaleru Reseroir
under the Telugu Ganga Project will
be closely monitored and suitable action will be taken
to maintain the current level of supply of
water to the Chennai citizens ,until the next
In order to treat additional water to be drawn under the Telugu Ganga
Project,
additional treatment capacity of 530 MLD
is being constructed at Chembarambakkam with assistance from the French
Government. Works are under
progress. So far, 45% of physical
work has been completed. The
balance works will be completed by May 2005.
The expenditure incurred so far is Rs.5977.00 lakhs.
The Revised estimate for 2004-2005 is Rs.4101.00 lakhs and Budget
estimate for 2005 - 2006 is Rs.5164.00 lakhs.
The Second Chennai Water Supply Project was
taken up during February, 1996, with the World Bank Assistance at a cost of
Rs.778.79 crores and most of the works contemplated under this project had been
completed. Some of the major works such as construction of Water Distribution
stations (7 nos), Laying of Clear Water Transmission mains ( 36 km),
Strengthening of Water Distribution system in 11 zones were taken up including
leak detection rectification works covering about
70% of Chennai City Area.
Installation of Vaccuum Feed Chlorinators in the Water Distribution
Stations, Refurbishment of the existing Kilpauk Water Treatment Plant and
installation of 44 Nos. electromagnetic flow meters were completed during the
year 2004. Expenditure in the year
2004-2005 is Rs. 12.83 crores.
For effective operation and maintenance of water supply and sewerage
system and asset management, Metrowater proposed to implement GIS based
database. As a pilot study, the Consultancy work of preparing such GIS data has
been taken up in nine depots from 70 to 78 in Area-V of CMWSSB, through M/s.
Descon Ltd., Calcutta
for a contract value of Rs.58,29,660/- and the work has been completed.
The basemaps have been procured from National Remote Sensing Agency,
Hyderabad.. These maps covered the
operational area of CMWSSB, which is approximately 192.Sq.km.
On completion of the pilot study, it is
proposed to examine and extent this GIS work for rest of the city area.
The
sewerage network in Chennai City was installed in the year 1891 and at present
the sewerage network has coverage of 98% of its area. In order to cope up with the increased sewage flow resulting
from water supply augmentation schemes under implementation and to prevent the
overflow of sewage into the city waterways, the Chennai City River Conservation
Project has been taken up at a cost of Rs.720.15 Crores with Government of India
grant Rs.491.52 Crores and Rs.228.63 Crores being borne by CMWSSB
and the work has been taken up in sixteen packages and nearing
completion. All the works including construction of 4 (new)
Sewage Treatment Plant units are programmed
to be completed by March 2005.
An
amount of Rs.288.53 Crores has been spent so far towards the above Project.
NRCD has released an amount of Rs.254.42 Crores only.
The slums located on the banks of Chennai City waterways are discharging
the sewage directly onto the
waterways and polluting there. In order to prevent discharge of sullage/sewage
from the slums into the waterways, it is proposed to provide sewerage facilities
to the slums located on the banks of waterways in the Chennai City .
Accordingly, it has been proposed to provide sewerage facilities to the
slums on the banks of waterway by CMWSSB at an estimated cost of Rs.1990.57 lakhs.
The expenditure for the above scheme is to be borne by the State
Government. By executing the above
project overflow of raw sewage into the City waterways can be prevented.

(Knight Piesold) to reassess the Ground water potential in Araniar Koratalaiyar
Basin was started and studies
regarding transfer of water use will
be carried over into the Third Chennai Project.
(3)
Unaccounted For Water In Left Out Areas
Earlier
studies have indicated that there was considerable loss of water in the system
both in the mains and in house service connections. Hence the Leak Detection and Rectification works were taken
up to reduce the level of unaccounted of water in phases with World Bank funding
under Second Chennai Project. Under
this project, 1,95,000 Nos. of house service connections have been
renewed and renewal of choked up mains for a length of 585 km was
completed.
It is proposed to take up
renewal of choked up AC/PVC/CI mains in the left out areas to a length of about
300 kms. and to renew the balance house service connections ( about 80,000 Nos.)
(4)
Water supply infrastructure facilities in Adjacent Urbanised Areas
(AUA) and Distant Urbanised Areas (DUA)
Pending finalisation of Master Plan, works in 12 local bodies have been
completed towards strengthening of transmission mains and storage capacity.
The distribution system in most of the local bodies is to be provided so
as to effect house service connection.
In view of providing water supply to AUAs and DUAs, water supply
distribution system for a length of 898 kms and water distribution stations are
to be provided after finalising the funding arrangements.
II.
NEW VEERANAM EXTENSION PROJECT:
During
the years of deficit rainfall, water in the Veeranam Lake may not be sufficient.
However, water supply to Chennai has to be maintained during this period
also. So, it was decided to implement a project called New Veeranam
Extension Project to draw sub surface water in Kollidam riverbed pumped to
Sethiathope and then to Chennai through the New Veeranam Project infrastructure.
The Government has accorded Administrative approval for this Project to
be implemented in five Packages vide G.O.Ms.No.9, dated 28.1.2005 for Rs.300.00
Crore. Out of this Rs.300 Crores,
1/3rd of the expenditure will be met out by the Government and the balance 2/3rd
will be met by Chennai Metropolitan Water Supply and Sewerage Board by raising
loans from the TUFIDCO/Commercial Banks.
The
proposed scheme is to draw 150 mld sub surface water from the Kollidam river by
constructing 6
Nos. of Collector Wells between mileages 39/3 and 59/0 in the Kollidam river.
This proposal envisages that the water from the Collector Wells will be pumped
to a sump and then conveyed by the pipeline to Sethiathope Raw Water Pumping
Station constructed under the Chennai Water Supply Augmentation Project-I for
onward transmission to Chennai City through the pumping and pipeline
arrangements of Chennai Water Supply Augmentation Project - I (New Veeranam
Project). This project will be executed in 12 months time.
The Government accorded administrative approval in the G.O.Ms.No.45,
M.A. & W.S. (Metrowater) Dept., dated 3.4.2002 for implementing the
Chennai Water Supply Augmentation Project-II at an estimated cost of Rs.493.00
Crores for constructing checkdams, reservoirs, percolation tanks etc., to store
surplus water for enhancing recharge in Kortalaiyar, Cooum, Adyar and Palar
river. After a detailed discussion,
revised proposals have been considered by the Government, by deferring of some
of the proposal and revised administrative sanction has been accorded for an
estimated amount of Rs.124.00 Crore under CWSAP-II. The Government also provided
1/3rd of the project cost as capital grant and released Rs.10.00 Crores towards
the grant. It is proposed to tap about 60 mld of ground water from the above
sources by implementing the following works.
a)
Construction of check dam across Palar river at Vayalur and conveying the
water to the proposed water treatment plant at Mangalam and inject the same in
the existing CWSAP-I pipeline after treatment.
b)
Construction of 4 Check dams across Adyar at Manapakkam, Nandambakkam,
Anakaputhur and Cowl Bazar.
c)
Rehabilitation of 2 check dams across Cooum at Paruthipattu and
Kannapalayam.
d)
Construction of Water Treatment Plant of 20 mld capacity at Mangalam.
e)
Construction of transmission main for conveying 20 mld of water from
Vayalur to Water Treatment Plant at Mangalam with injection arrangement to CWSAP
pipeline.
An
amount of Rs.7.9 Crores has already been released by Metrowater to PWD on
20.12.2004 as an advance for taking up the works which are to be executed by PWD.
Tenders were called for by PWD and the works are programmed to be
completed in 18 months time from April 2005.
Urbanisation of adjacent areas surrounding the city is
increasing day by day. 20
such Adjacent Urbanised Areas surrounding the city have been listed.
These Adjacent Areas are administered by Municipalities, Town Panchayat,
Village Panchayat, etc. To improve
the public health and environmental conditions, proposals are under formulation
for providing comprehensive sewerage schemes to these areas.
A Master Plan for furnishing the Detailed Report on technical and
financial aspects of providing sewerage scheme is to be prepared.
The probable cost for providing sewerage system including conveyance of
sewage to nearby STPs has been worked out as
Rs.631.00 Crores and land and capital cost for constructing additional
treatment units at the STPs of Metro system as Rs.616.00 Crores with an
additional O&M Cost of Rs.17.56 Crores per annum.
Incidentally
some of the Local Bodies have formulated proposals for providing sewerage
schemes to their areas by availing funds from the financial institutions like
TNUIFSL, TUFIDCO, etc. The works will be executed by CMWSSB as deposit works
once the respective Local Bodies make available
the funds for the work.
The Detailed Project Reports for providing sewerage schemes to
Thiruvottriyur, Avadi, Ambattur, Pallavaram, Porur, Madhavaram, Kathivakkam
etc., have been received by CMWSSB for scrutiny.
About 98% of the streets/roads in the city have been provided with sewer
lines by CMWSSB. Still some streets
are found to be uncovered with sewer lines.
Public representations are being received from such streets. During the current financial year estimates for providing sewer lines for a length of 10.46 k.m.
have been prepared at a total cost of Rs.1.78 crores. The works are under various stages of implementation.
This work is being continued for coverage of 100% of the City area.
