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.
