       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.

(i) Surface Water Components  

  • Collection of flow data from Gaugings Stations in various river courses.
  • Collection of storage data from major tanks by installing Automatic Water level Recorders.
  • Monitoring of return / regenerated flows in select command areas and measurement of flow into sea.
  • Surface water sampling locations have been designed for all river basins in Tamil Nadu and samples are being collected once in a month during flow period to assess  the surface water quality.
  • Collection of Hydrolmeteorological data from raingauge stations, full climatic stations and automatic weather stations.
  • Collection of data on reservoir sedimentation and water quality data by establishing level - I water quality laboratories and silt laboratories.
  • Improvement of infrastructure facilities - Office buildings, Site stores & Quarters etc.,
  • Creation of data base in the dedicated hydrological surface data processing software Viz., HYMOS.
  • Exchange of information within the State and Central Organisation through the State Data Storage Centre.
  • The data are collected and primary validated in the sub-divisional data processing centre and are secondary validated in the divisional data processing centre before sending to state data processing centre.
  • Inter agency validation of data are done with India Meteorological Department and Central Water Commission.

(ii) Ground Water Components

·      Collection of water level data from the existing 1746 observation wells.

·     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:

I   Primary Validation at Divisional Data Processing Centre.

ii  Secondary validation at Regional (Circle) Data Processing Centre.

iii. Integrated Hydrological validation at State Data Processing Centre.

 

  • Creation of Districtwise database in Groundwater Data Entry Software (GWDES) at SDPC.
  • Upgradation of four water quality laboratories with new building and sophisticated equipments to analyse more pollution parameters.
  • Exchange of information within the State and Central Organisation through the State Data Storage Centre.

 (iii) Water Quality:

 ·          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.

 (iv) Data Storage Centre  

  1. Stores and administers the storage of all field and processed hydrological data collected in the State.
  2. Makes the data available to authorized Hydrological data users.
  3.  Maintains HIS-catalogue of all data stored in its own data base and those stored in the data bases of other States and of the Central Agencies.

(v) Creation of GIS Data sets under Hydrology Project - I.  

Spatial 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.

 (vi) Software Packages  

  • Under the Hydrology project-I all the data pertaining to groundwater and surface water are entered in data entry softwares like Ground Water Data Entry System and Surface Water Data Entry System respectively. To process the GWDES data, a dedicated software called  GEMS, developed and installed in the SDPC by  M/s. Tata Infotech. Various modules such as water quality, water level, rainfall, geophysics water resources assessment etc., are customised to suit our data needs.

  • Surface water data are entered in the software, Surface water Data Entry System (SWDES) and further validated in a GIS base software Hydrological Modelling System (HYMOS).

  •  Groundwater data are entered in the software, Groundwater Data Entry System (GWDES) and further processed in a GIS base software "Groundwater Estimation and Management System (GEMS).

  • Water quality data are entered in the software water quality data entry system (WQDES).

  • All the above processed data are stored  in an in house developed software water information system data online management (WISDOM) which has a relational data base and stores data in catalog forms  for early dissemination.

  • Select application software packages procured and installed in SDPC computers are:

1.                Microstation (J) and Descartes for GIS applications.

2.                Surface Water Modeling Software (SMS)

3.                Groundwater Modeling Software (GMS)

7.     Hydrological Data Users Group(HDUG) :

 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 its chairman.  

3 task groups were formed to accomplish the following tasks.

  • Exchange of data between State Data Centre and Central Agencies like IMD,CWC,WB  etc.
  • Pricing  of validated data before dissemination to various user organizations.
  • All matters  relating to water quality issues.

 The 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.  

The HDUG have to continue to function and meet periodically in the years to come to facilitate effective dissemination of quality data among various stake holders.  

       8.  Creation Of Groundwater Awareness

 

Public 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.

 

 This is being achieved by creating an Awareness Unit for Groundwater in all the Groundwater Divisions of this department.  

·         The 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,

·        Unemployed 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 village,  

·         Disseminate Groundwater Awareness information in the form of bulletins, pamphlets, posters   and stickers, 

·         Monitoring, observation and feed back of the public views regarding the Groundwater Awareness campaign,  

·         Liaisoning and carrying of the Groundwater Awareness News and Information to the rural villages. 

·         Large 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 assistance. 

·         Geophysical survey and instant water quality analysis were demonstrated at campaign premises itself.

·         Consultancy 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.

·         So far 180 programmes were conducted.

    Messages to be conveyed :

 

The judicial use of groundwater necessity for conserving.

 

Conjunctive use of ground and surface water.  

Methods of artificial recharge of groundwater through rain water harvesting and the assistance extended by our department towards it. 

Benefits of rainwater harvesting, both qualitatively and quantitatively.  

Enlightening the citizens about the future demand of water and the necessity to create additional water resources (conservation).  

Big farmers can be requested to apportion some parts of their land to augment rainwater harvesting.

Ways to avoid pollution to ground and surface water.  

Instant testing of the surface and groundwater quality of the village and recommending suitable measures.  

Information about the harmful effects of polluted water to human life. 

Usage of open pits and defunct wells for storing rain water.
