Urban Water Supply Schemes

Section: Schemes pages are not under access control

General

Tamil Nadu is a rapidly urbanising State. The urban population of the State stood at 3.50 crore as per 2011 census, constituting 48% of the total population. With the growth in urbanization and improving quality of life, provisions for adequate infrastructural services are taking greater importance. The urban areas of Tamil Nadu are classified depending upon the civic status (except Chennai Corporation) as follows.

S. No Categories Nos
1 Corporations 20
2 Municipalities 138
3 Town Panchayats 490
  Total 648

The Government is providing increased allocation in each and every plan for these sectors including provision of safe drinking water to urban population. There is significant increase in coverage in each Plan period. However, due to the increase in demand, over exploitation of surface/ Sub surface water and quality related inconsistencies, full coverage remains an eluding factor.

The Government has taken appropriate actions for the protection and improvement of potential of water bodies by constructing suitable recharge structures.

Agencies involved

The task of providing safe drinking water and sanitation facilities for the entire State except Chennai Metropolitan area, rests with the Tamil Nadu Water Supply and Drainage Board. (Water supply schemes on a limited scale are being implemented by urban local bodies also). The schemes on completion are handed over to the respective local bodies for maintenance. Schemes of composite nature covering more than one local body are being maintained by TWAD Board. Here too, the maintenance of the internal arrangements is the responsibility of the respective local body. Chennai Metropolitan Water Supply and Sewerage Board (CMWSS Board) is vested with the responsibility of providing water supply and sewerage facilities within the metropolitan area of Chennai.

Funding Agencies

Water supply to urban towns are being funded by various sources, uiz.,

  • Govt. of India, under JnNURM, UIDSSMT AMRUT, IUDM
  • Govt. of Tamil Nadu under Minimum Needs Programme,
  • Capital Grant fund,
  • World Bank aid through TNUDP III,
  • German Bank aid under KfW, Japan aid under JICA. The local bodies are also contributing from their own funds.
