CWSS TO 1153 HABITATIONS IN 9 UNIONS AND PERAVURANI , PERUMAGALUR AND ADIRAMAPATTINAM TOWN PANCHAYATS IN THANJAVUR DISTRICT WITH KOLLIDAM RIVER AS SOURCE
 
Designed Quantity : 38.11 MLD            Project Cost : Rs 495.70 Crores
           Technical Sanction : Rs.490.125 Crores

 PREFATORY

Thanjavur  District comprises of 08 Taluks, 14 Panchayat unions, 22 Town panchayats and 3 Municipalities.

Out of  14 panchayat unions,   204 habitations in Bhudalur union are fully covered with river source.   In the unions Thirupananthal, Thiruvidaimarudur, Kumbakonam, Papanasam, Thiruvaiyaru and in Thanjavur, the habitations are partly covered by the river sources.

This project area comprises of 1003 rural habitations in Pattukottai, Peravurani,  Sethubavachatram, and Madukkur unions  and  wayside 150 Habitations in Papanasam, Thiruvaiyaru, Thanjavur, Orathanadu and Thiruvonam unions and also   three town panchayats namely   Peravurani town panchayat, Perumagalur Town Panchayat  and Adhirampattinam town Panchayat.

 Present Water supply Scenario

At present protected water supply is being provided to all 1153 rural habitations with IPP schemes, EPL and Mini power pump schemes with local sources

 NECESSARY FOR THE PROPOSAL

The trend of the water level   in the project area reveals the depletion of water level over long term.  This trend may cause the reduction in the available yield in future.   Further   , the clear   potable category for the water samples collected in the   area is also less

Hence it is necessary to formulate a CWSS to the above 1153 rural habitations with river source to provide sustainable quantity and quality of water free from Chemical impurities.

In addition, based on the Announcement made, the hamlets of the  Peravurani Town Panchayat, Perumagalur  Town Panchayat  and Adhirampattinam  Town Panchayat are included in the  scope of  this project.
