[1] This Project has two following alternatives[2] Water is fed from the Puttamgandi foreshore pump house located at 16°36′37″N 79°07′01″E / 16.61028°N 79.11694°E / 16.61028; 79.11694 (Puttangadi Pump House) in to the nearby Puttamgandi tank from Nagarjuna Sagar reservoir.
[5] Water is supplied from the Puttamgandi tank by gravity to the entire irrigated area of the project via balancing reservoir called Akkampalli reservoir with 1.5 tmcft storage capacity.
To eliminate the need of expensive water pumping and facilitate water flow by gravity to the Akkampalli reservoir, it is envisaged to bring water from Srisailam reservoir to the plains of Nalgonda through two tunnels of a total length of 50.75 km (31.53 mi).
This scheme is known as Srisailam Left Bank Canal (SLBC) project.
Puttamgandi tank water storage can be enhanced significantly by enlarging its water area and water depth by constructing earth bunds taking advantage of nearby continuous hillocks on three sides of the tank.
