 In these circumstances, adequate water is to be stored above the 502 ft MSL to maintain 100% assured water source without depending totally on NS reservoir.This is possible by constructing a balancing reservoir by separating some area of the NS reservoir with a new dam across the Bhimanapalli Vagu tributary at just upstream of the Puttamgandi PH approach channel.This new dam with FRL MSL, would not submerge any additional area other than the area already submerged by the NS reservoir.
