SRISAILAM RIGHT BANK CANAL

Preamble

The KWDT in 1973 has allocated 800 TMC (75% dependable flows) of Krishna waters to AP State. Under this award, the state is entitled to make any adjustments and re-allocations within the allotment made specially to the state and also entitled to utilize 11 TMC of regenerated water as its share to irrigate 1,90,000 Acres of Nandyal, Banaganapalli, Koilkuntla Taluks of Kurnool Dist. and Jammalmadugu taluk of Kadapa District.The source of water to the scheme is river Krishna tapped from foreshore of Srisailam reservoir ( Now named as N.S.R.S.Project ). Water will be drawn from reservoir through Pothidreddy padu head regulator with an approach channel of 3.40 Kms long inside the reservoir and from the head regulator the Sri Sailam Right main canal is aligned cutting across the Mittakandala ridge up to Banakacherla village to enter the Kundu sub-valley. At Banakacherla, a cross regulator complex is constructed and from this point the main canal i.e.,SRMC branches into three canals. The right side canal taking off to feed SRBC scheme with a capacity of 5,000 Cusecs, left canal taking off to feed the TGP and the middle escape channel to feed K.C.Canal. Thus SRBC starts from Banakacherla cross regulator complex and runs for a length of 198.00 Km and joins in pennar river duly filling two balancing reservoirs one at Goralkallu village and another at owk village.The length of canal in Kurnool district is 141 km. This S.R.B.C Scheme was formulated to irrigate an Ayacut of 1,90,000 Acres to benefit the chronic drought prone areas in 82 villages of Nandyal, Panyam, Banaganapalli, Owk, Koilakuntla, Vuyyalwada and sanjamala mandals of Kurnool district (1,57,422 Acres ) and 18 villages of Jammalamadugu mandal of Kadapa district (32,578 Acres).
