CWSS to 7 Town Panchayats and 395 Rural Habitations in Rajapalayam, Srivilliputhur, Watrap and Sivakasi (Part) Unions in Virudhunagar District with River Tamiraparani as Source Near Mukkudal.

Original Quantity : 18.17 MLD
Revised Quantity : 18.16 MLD
Project Cost : Rs.173 Crore
Technical Sanction : Rs. 170 Crore

Virudhunagar District consists of 7 Municipalities, 9 Town Panchayats and 1,891 Rural Habitations(including 263 new Habitations) in 450 Villagel Panchayats.

This Project area comprises of 7 Town Panchayats namely Seithur, Chettiyarpatty, Mamsapuram, Sundarapandiam, W.Pudupatty, Watrap, and S.Kodikulam and 395 Rural Habitations in Rajapalayam, Srivilliputhur, Watrap and Sivakasi unions in Virudhunagar District .

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.
