Urban Water Supply Schemes

Section: Schemes pages are not under access control


Tamil Nadu is a rapidly urbanising State. The urban population of the State stood at 34.95 million as per 2011 census, constituting 48% of the total population. With the growth in urbanisation and improving quality of life, provision of adequate infrastructural services has assumed 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 11
2 Municipalities 124
3 Town Panchayats 528
  Total 663

The Government have provided increased allocation in each plan for this sector for the provision of safe drinking water to urban folk. There is significant coverage increase in each Plan period . However,due to the increase in demand, full coverage remains an eluding factor. Among other notable reasons are, over exploitation of surface/ Sub surface water and quality related inconsistencies

The Government have taken appropriate actions for the protection and for increasing the potential of water bodies by construction of 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
