Project in Brief
Upper Indravati Irrigation Project, a part of Upper Indravati multipurpose project, is located in Nowarangpur and Kalahandi districts of Odisha. The Multi purpose project was approved by Planning Commission in the year 1978 for Rs.208.14 crore (Includes cost of irrigation component), for providing irrigation to a Culturable Command Area (CCA) of 1,09,300 hectare (ha), including lift irrigation (CCA - 33032 ha). This multipurpose scheme comprises of four dams and eight dykes to form an integrated reservoir having gross storage capacity of 2300 MCM.
The main dam is across the river Indravati, while the other three are on its tributaries, namely, Podagada, Kapur and Muran. The project envisages both irrigation and power generation with installed capacity of 600 MW. The Power House is functional since 1999. The regulated release from the power house through tail race channel is picked up at a 117 meter long barrage at Mangalpur on the river Hati, a tributary of the Tel in Mahanadi basin, (this involves interbasin transfer of water i.e. from Godavari to Mahanadi basin) to provide irrigation to chronically drought prone Dharmagarh and Bhawanipatna subdivisions of Kalahandi district. Hati barrage was completed in 1987. The major components of the project are:
Existing Dams (The four dams form intergated reservoir)
(a) Indravati Dam
- 539m long, 45 m high masonry gravity dam on Indravati river.
- 129 m long centrally located gated spillway
- 4 nos. dykes on left flank & 4 nos. dykes on right flank
(b) Padagada Dam
- 462 m long, 57.5 m high homogeneous rolled earth fill dam without spillway on Padagada river.
(c) Kapur Dam
- 537 m long, 64 m high homogenous earth fill dam without spillway on Kapur river.
(d) Muran Dam
- 494 m long, 65 m high masonry gravity dam on Muran river
- 90 m long centrally located gated spillway
- 7.0 m dia, 3934 m long HRT
- 20 m dia, Surge tank, (restricted orifice type)
- 2 nos, 5.2 m dia, 293 m long each pressure shafts
- 4 nos. 3.25 m dia, 790 m long each penstock
- Surface power house with installed capacity 600 MW (4 x 150 mw)
- 9 km long Tail race channel
Upper Indravati irrigation project
- 117 m long Barrage at Mangalpur to pick up water from tailrace channel
- 52 km long left main canal with distribution system
- 106.4 km long right main canal with distribution system
- Left Canal System - CCA - 49,076 ha, Completed with OECF Aid
- Right Canal System - CCA - 27,192 ha, Completed in 2004-05 under AIBP
- Extension of Left Canal System CCA - 10,224 ha, Presently under AIBP
- Extension of Right Canal System CCA - 15,260 ha, Presently under AIBP.
- Lift Canal System - Not taken up yet.
Total:- 1,01,760 ha
Upper Indravati Extension
In 2002-03, extension of Left Canal System was proposed through a distributary beyond river Tel, named as Golamunda distributary, proposing additional CCA of 10,224 ha, with 164% intensity. Along with left canal system, an extension proposal for the right main canal was also formulated beyond river Sagada upto the river Ret, to irrigate 15,260 ha of additional CCA with 164% intensity (annual irrigation is 41790 hectare) and to provide drinking water to Bhawanipatna town. Both the proposals were accorded investment clearance by the Planning Commission during 2002-03, for an estimated cost of Rs.136.67 crore (1998 price level). This work is presently continuing under AIBP. Further the cost of the project has been revised to Rs.564.77 crore at 2008 price level by the 98th TACTechnical Advisory Committee held in July, 2009 and got investment clearance from Planning Commission during February, 2010.
