B.R.R. VAMSADHARA PROJECT PHASE - II OF STAGE - II

Preamble

The Phase-II of Stage-II of Vamsadhara Project is intended to create an Irrigation Potential of 45,000 Acres and stabilizing the existing ayacut of 2,10,510 Acres under Left & Right Main Canals. The cost of the project is Rs. 933.90 Crores and administratively approved vide G.O.Ms. No. 33, dated 25.02.2005.

The Project Components are:


1) Construction of a side weir on Right bank of Vamsadhara River at Katragada (Village) Bhamini Mandal for diverting the flood waters into flood flow canal. A regulator for regulatory flows into flood flow canal and silt excluder for diverting excess water into the river.


2) A Flood Flow Canal about 34 Km length with two balancing reservoirs at Singidi and Parapuram Villages en-route irrigating 20,000 Acres.


3) Hiramandalam Reservoir with 19.05 Tmc capacity with head sluices for High Level Canal, Link Canal and Spillway regulator.


4) A High Level Canal to irrigate 5,000 Acres.


5) A Link Canal to connect the Right Main Canal @ Ch. 2.670 km from Hiramandalam Reservoir to supplement the deficit requirement under Left & Right Main Canals.
