HYDROLOGY PROJECT - I
World Bank have come forward to assist five Government of India agencies
viz CGWB, IMD, CWC, NIH and CWPRS, and nine states viz., Gujarat,
Maharashtra, Karnataka, Kerala, Tamilnadu, Andhra pradesh, Orissa,
Madhyapradesh and Chattisgarh in the formation & execution of
project is intended to assist the Government of India agencies and the
participating states setting up of a reliable and well designed network
for collection, transmission, processing, storage and dissemination of
data covering Surface water and Ground water both in terms of quantity

6 . Integrated Data Centre For
Surface Water And Ground Water - Activities:
The project can be broadly classified into two components viz.,
Surface water component and Groundwater component.
Surface Water Components
(ii) Ground Water Components
Collection of water level data from the existing 1746 observation
Construction of 690 piezometers in the hardrock areas and 162
piezometers in the sedimentary formations and collection of water levels
from digital water level recorders installed under HP.
Validation of water level data in three stages:
Primary Validation at Divisional Data Processing Centre.
Secondary validation at Regional (Circle) Data Processing Centre.
Integrated Hydrological validation at State Data Processing Centre.
About 3400 ground water
samples are being collected from shallow
observation wells and bore wells. Surface water samples in all the 17
river basins are also monitored in 71 locations. The samples are tested
for the suitability of domestic, agriculture and industrial purposes.
To carry out the above
study four laboratories are functioning at Chennai, Trichy, Madurai and
Pollachi. All the above Laboratories are recognised under EPA (1986) by
the Central Pollution Control Board (CPCB) Delhi.
The laboratories are
having the facilities to analyse General Parameters, Pollution Parameters
in addition to the Bacteria analysis.
The Chennai Laboratory is
having the facility to analyse pesticide and toxic metals. The presence of
toxic metals and peticides in Ground and surface water are also being
studied by this Wing.
Ground Water quality data are also available from 1972 onwards.
For general public and other Departments water samples are analysed
at prescribed rates.
Data Storage Centre
(v) Creation of GIS Data sets under Hydrology Project - I.
data base is organised with 15' by 15' geographic area, corresponding to
Survey of India toposheet of scale 1:50,000. These digital data sets are
of high quality following the Quality Checking / Quality Assurance test
strategies proposed by the World Bank.

Hydrological Data Users Group(HDUG) :
is a State / National level representative group of current and potential
large scale and repeat users of hydrological data, who have a stake in
water resources utilization, assessment and management. In Tamilnadu, the
HDUG was constituted with 72 members with the Chief Engineer, WRO,(SG&SWRDC)as
task groups were formed to accomplish the following tasks.
task groups have held discussions on the terms of references and made
certain recommendations. The recommendations have been circulated to the
group members and are to be placed before the Committee, SLSC and NLSC for
approval and adoption.
HDUG have to continue to function and meet periodically in the years to
come to facilitate effective dissemination of quality data among various
Creation Of Groundwater Awareness
awareness for using groundwater judiciously is
the need of the present day as the requirements of water are
increasing year by year. The limited available groundwater is often
polluted in many places. In this juncture, there is a strong need to
educate the public about conserving the available groundwater quantity as
well as quality.
is being achieved by creating an Awareness Unit for Groundwater in all the
Groundwater Divisions of this department.
groundwater awareness unit will associate with the NGOs, village Panchayat
President, VAO and other important personalities of the area while
covering the village concerned. Wide publicity is given to the other
district authorities, such as Collectorate, Agricultural Department,
Pollution Control Board, Public Health Department Block and Municipal
authorities, WRO, PWD about the activities of the Groundwater Awareness
Unit and its action programme,
graduates with specified qualifications are employed on service contract
basis to arrange timings and liaisoning with the local village heads for
further discussion with the department officials for fixing a mutually
convenient date for conducting Groundwater Awareness Day in a particular
Groundwater Awareness information in the form of bulletins, pamphlets,
posters and stickers,
observation and feed back of the public views regarding the Groundwater
and carrying of the Groundwater Awareness News and Information to the
number of general public including women folk are attending the above
campaign. They were impressed by the effective way of reaching them to
provide the technical know how and expertise combined with voluntary
survey and instant water quality analysis were demonstrated at campaign
services were done free of cost for those small and marginal farmers of
that area who have turned up for this campaign, in order to propagate the
message to the farmers for safe guarding the groundwater.
far 180 programmes were conducted.
to be conveyed :
judicial use of groundwater necessity for conserving.
use of ground and surface water.
of artificial recharge of groundwater through rain water harvesting and
the assistance extended by our department towards it.
of rainwater harvesting, both qualitatively and quantitatively.
the citizens about the future demand of water and the necessity to create
additional water resources (conservation).
farmers can be requested to apportion some parts of their land to augment
to avoid pollution to ground and surface water.
testing of the surface and groundwater quality of the village and
recommending suitable measures.
about the harmful effects of polluted water to human life.
of open pits and defunct wells for storing rain water.
Details Of R & D Studies Under Hydrology Project - I
Under the World Bank Aided Hydrology Project-I, the following R & D studies have been taken up. These R & D studies are considered in typical areas, so as to carry the findings of the study to other areas in the state of Tamil Nadu.
