In the same vein he added if Mettur Dam was desilted another 10 tmc can be saved.
Construction of 10 check dams/barrages on the Cauvery and Coleroon will save another 60 tmc of water.

The scheme involves the digging of a feeder canal for 38 kilometre from Then Pennai to Cheyyar river which joins Palar at Thirumukkudal. The scheme would lead to water flow in Cheyyar besides Palar.
The river Palar was providing drinking water to the areas of Alandur, Pammal and Anakaputhur earlier, but these areas had been delinked recently and connected to metro water network.

The river’s aquifers would get recharged if the Pennari-Palar link project is completed.
Commenting on the delay, a PWD official said the Centre had passed a new land acquisition act which had increased the cost of compensation for the land owners when government takes up land for projects.
