water from the back waters of Polavaram reservoir. As part of redesigning, Rajiv Dummugudem Lift Irrigation Scheme (RDLIS) has been merged with Indira Sagar Rudramkota Lift Irrigation Schemes (ISRLIS) and has been named as Sita Rama Lift Irrigation Project (SRLIP). Sitamma Sagar Barrage has also been planned to create pondage of 36.5 TMC, for lifting water in this irrigation scheme. Dummugudem Barrage on Godavari Khammam District

left canal near , water can reach by gravity to the Nagarjuna Sagar reservoir when its water level is at minimum draw down level of MSL. It is more economical and purposeful to install a pump house drawing water from the deep cut portion of the canal to pump water up to Nagarjuna Sagar full reservoir level at MSL with nearly 27 meters lift. Thus it is a viable project by eliminating the need of lifting water by 80 meters from tail pond to the Nagarjuna Sagar reservoir. This saved pumping head can be used to pump water from the Nagarjuna Sagar reservoir to Srisailam reservoir for supplying irrigation water to Kalwakurthi lift irrigation Scheme, Srisailam left bank canal, Dindi lift irrigation scheme, Palamuru lift canal, Nettampadu lift, Bhima lift, etc located in Telangana with 100% water dependability for all the projects drawing water from the Krishna river.
