Vasishta Nadi carries the drainage of Kalrayan Hills and flows through Attur, Thalaivasal and Cuddalore district with check dam at Pakkampadi and Periyeri / Aragalur border. This river flows in Tiruchirapalli and joins Sweta Nadi before flowing into the Bay of Bengal. Vasishta Nadi flows on the north and east part of the village. The Eri (agriculture reservoir - diverted from river) feeds many parts of the wet lands. Other areas are feed by and deep open wells or borewells tapping the aquifer. There is also a concern that the ground water table is going down in this region due to excessive exploitation of ground water for agriculture.
