Scheme :: Bridge-Cum-Barrage

Introduction to the scheme

Since Independence a huge investment has been made for development of irrigation.Despite that the target is short of the desired level because of politico -socio-economic and technical reasons. In addition to this ,topographic and geographic factors do play their games limited by the contours contemplated by the project features.The backward pockets of the state are deprived of getting irrigation facilities due to the reasons stated above. The present vision of the Government of Odisha to provide at least 35% irrigation in each block will be accelerated through the mega lift irrigation schemes where no other irrigation facilities like flow irrigation from major, medium and minor irrigation projects are available . To fulfill the above goal ,the DoWR is focusing integration of different Water Resources Developmental schemes like Check Dams, Mega Lift Projects,Bridge-cum-Barrage and Deep Bore Well etc. 


The proposed Bridge-cum-Barrage scheme envisages lifting of water mostly from surface water sources to a delivery chamber at higher elevation and providing irrigation to the command below through pipes under gravity.

The scheme is very much encouraging from the following respects.

i)No submergence for head works.

ii)No land acquisition for distribution system,hence no public agitation.

iii)Negligible /Nil forest clearance.

iv)No massive structures like CD,HR,VRB,Fall etc.are required. Hence cost is drastically reduced.

v)Small gestation period.

vi)Immediate realization of benefits

vii)No hue and cry from reservoir induced seismcity and water logging.

viii)The proposed clusters being smaller are expected to suit to-operative farming and better Co-ordinate actives of Panipanchayat.

ix)Connectivity of road along with the water storage structures.


i)The broad objectives of Check Dams(In-stream storage Structures) are:

ii)To provide drinking water facilities in the villages along both the sides of the river after monsoon period.

iii)Ground water recharge

iv)To provide incidental irrigation during late Khariff and Rabi by storing water at the end of monsoon mainly through lifting devices.

v)Irrigation use of water flowing down drainage channels.

vi)To divert water from perennial /semi perennial streams in hilly areas for irrigation purpose 

vii) Other uses by villagers like bathing,washing,fishing,recreation etc. depending on location and potentiality.


Background of the Bridge-cum-Barrage Project:-

Odisha depends largely upon monsoon for its water Resources. South west Monsoon triggers rainfall in the state. About 78% of total annual rainfall occurs during the period from June to September. In addition to seasonal availability the rainfall in the state also shows a spatial variation. Under normal conditions the State receives annual precipitation of about 230.76 billion cubic meter (BCM).Of the total precipitation, a part is lost by evaporation ,transpiration and deep percolation and a part is stored in the form of ground water reserve, the remaining appears as surface runoff. Considering the topographical and geological limitations,75% of the average annual flow can be utilized. Till date a storage capacity of 17 BCM has so far been developed through completed major,medium & minor (flow) projects .The projects under construction will contribute to an additional 1.47 BCM.The per capita water storage needs substantive improvement keeping in view the challenges going to be faced by water sector.

Taking into account the limitation of  storage schemes and their long gestation period ,State government is keen to utilize a part of the surplus surface runoff flowing down to the sea through interventions such as Check dams or In stream storage Structures in small rivers /streams and anicuts in bigger streams/rivers.

As per the guide lines for construction of check dams it has narrated that -"After success of the 1st phase construction of check dams and as per the demand from farmers /industries ,the state Government may suitably modify/amend /alter any guidelines/norms in the scheme if any difficulties/problems arise during implementation of the scheme for achieving better performance under the scheme."

So, it has decided that the check dams can be upgraded to the Barrage-cum-Bridge projects at the feasible sites:so that the water storage height can be increased as well as road connectivity ,ground water recharge, drinking water supply, mega lift and other facilities can be availed from the scheme.

A state level Monitoring Committee was held on 4 th June 2012 under the Chairmanship of Chief secretary Govt. of Odisha to implement the Barrage-cum-Bridge Project. It has been decided that the preliminary survey work to be completed by the respective executive Engineers and DPRs for the B-C-B will be placed before TAC in the month of july,2012.(List of schemes attached at Annexure-I). The command area has been chosen in considering connectivity source ,water availability & non-interference with other irrigation schemes .The water requirement has been assessed basing on the cropping pattern suggested by the state agriculture department. Since these areas are not covered by any major, medium and minor irrigation projects the proposed Bridge-cum-Barrage scheme will meet the objective of the local farming community for better agricultural output.

It is expected that the marginal farmers having limited undersigned holdings and be benefited. Since these marginal farmers having agriculture as the main stay of the economic  activity.
