P.M.Natarajan, Working Group member, Planning Commission, Government of Tamil Nadu, and a noted geologist, has welcomed the proposed Rs.1,560 crore-project to refurbish old tail-end sluices and construct new ones in the Cauvery delta which would facilitate groundwater recharge and arrest sea water intrusion. The proposal was announced by Chief Minister Jayalalithaa in the Assembly on May 7. “It is a good water management approach to improve entire irrigation command including tail end,” he told The Hindu here on Wednesday.
