[Tamilnadu water supply and drinage board ]
The Background

The provision of drinking water supply is an imperative need of the society. Thus a national water supply and sanitation programme was introduced in the social welfare sector in 1954. The Government of India provided assistance to the states to accelerate the pace of coverage of problem villages through the programme known as Accelerated Rural Water Supply Programme [ARWSP]. The entire programme was given a mission approach when the technology mission on Drinking Water and Related Water Management also called National Drinking Water Mission [NDWM] was introduced in 1986. This NDWM was renamed as Rajiv Gandhi Drinking Water Mission in 1991.

The strategies of rural water supply hitherto adopted revolve around the basic premise that provision of safe drinking water is the responsibility of the Government. The water is generally perceived by the public as a "social right". The Government has provided water supply schemes without community participation, which has created an expectation in the communities, that water is a free commodity and the functionality of the installations is a Government responsibility. Experience has revealed that this present approach has led to the failure of large number of water supply systems due to poor operation & maintenance and lack of participation and awareness among the users. In order to achieve sustainability, there is a general recognition that a transformation from supply driven approach to participatory demand based approach is required where the users get the services they wanted.

A nation wide survey conducted during 96-97 has revealed that even poorest of the poor are willing to participate in the implementation of the programmes, and to contribute towards operation & maintenance and part of the capital cost provided, reliable service is given and maintained. The principle of graded contribution would also inculcate a sense of ownership which in-turn will improve the overall functional efficiency of the system.

The Tamilnadu Water Supply and Drainage Board [TWAD] was formed on 14-4-1971 from the erstwhile Public Health Engineering Department , Govt. of Tamilnadu with the sole aim to provide protected safe drinking water in adequate quantity and sanitation to the general public. Administered by senior level Government Executives as the Board of Directors, TWAD Board is vested with the responsibility of providing drinking water supply and sewerage facilities through out the state of Tamilnadu [TN] except Chennai Metropolitan area.

Inline with the above perceptive, the RGNDWM has designed to adopt the community based demand driven approach instead of the government forced supply driven approach. As these projects, are proposed to be community participation oriented, a part [minimum of 10% of the proposal] of the capital cost should be borne by the community themselves. The balance amount is fully provided by the Government of India.The project envisages provision of sustainable water supply and sanitation facilities to the inhabitants of the project area with the following components.

  1. Installation of water supply schemes utilising, dependable sources thus a ssuring sustainable water supply.Water supply schemes will be either individual piped water supply scheme or combined water supply scheme or extension of existing water supply schemes involving one or more habitations.
  2. Provision of toilet facilities in rural schools
  3. Provision of drainage arrangements in the project habitations
The above programme will be implemented through the following institutional arrangements as laid down by the Government of India as given below.
  1. The State level water land sanitation mission [SWSM]

    Which is responsible for policy guidelines and implementation of the Project.

  2. The district water and sanitation committee [DWSC]

    Which is responsible for formulation and management of project implementation in the district and ensuring that the project development objections are achieved in the district.

  3. Village water and sanitation committees [VWSC]

    Which is responsible for ensuring community participation, arranging community contributions and involvement in operation and maintenance.

Sampling Procedures
  1. Sampling for Chemical examination
    1. Water for chemical examination should be collected in a clean, white 2 liter polythene container.
    2. The source from which water is collected should be in regular use. Otherwise the source should be adequately flushed before sampling. For hand pump sources, the water should be pumped and wasted for at least three to five minutes to clear all dirt, slime and turbidity. Water from wells should be taken in the middle at mid depth. For lakes, rivers and dams, the water should be collected near the off-take point.
    3. Before collection of sample, the container should be washed with the water to be sampled for at least two or three times.
    4. The water should be then filled completely in the container without leaving any air space.
    5. Place the inner cap. Place a polythene sheet [10x10 cm] in between the inner and outer caps. Screw the outer cap. Place another polythene sheet of same size over the outer cap and tie the neck with a rubber band or twine thread.
    6. Label the container with all required source particulars.
    7. The sample should be delivered to the lab within 24 hours from the time of collection.
  2. Sampling for Bacteriological examination
    1. For bacteriological examination, the water should be collected only in a pre-sterilized 250 ml glass bottle which could be obtained from any of the laboratories.
    2. The sample collection procedures will be explained in the laboratory when the sampling bottles are delivered to the customer.
    3. The sample should reach the laboratory within 6 hours from the time of collection. However when preserved in an icebox, the sample can be delivered within 24 hours.
    4. The sample should be labeled properly before it is dispatched.
