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.

broad objectives of Check Dams(In-stream storage Structures) are:
drinking water facilities in the villages along both the sides of
the river after monsoon period.
incidental irrigation during late Khariff and Rabi by storing water
at the end of monsoon mainly through lifting devices.
of water flowing down drainage channels.

villagers like bathing,washing,fishing,recreation etc. depending on

Background of the
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.
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
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.
