Present Water Supply Scenario:

At present, most of the Habitations are getting water from local and near by Bore Well Sources. Some of the habitations have been provided with water supply from Infiltration Wells in River Vaipar, River Arjuna, Gundar and River Vaigai. Moreover, the Rivers mentioned above are not perennial. The present level of service to the rural areas is 10 lpcd and to the Town Panchayat varies from 28 lpcd to 50 lpcd.

Need For This Proposal:

In Virudhunagar District, all the existing Bore wells and Open Wells are not sustainable. The Rivers flowing within this District are also not perennial. In order to enhance the level of service as per the norms, it is necessitated to formulate the above CWSS with River Tamiraparani as source.
