JURISDICTION OF NORTHERN ZONE
DUG WELL BUCKET IRRIGATIONThe Land was sandy,barren and farmers could hardly cultivate a single crop that was also risky
Drought was the regular events of the area at least once in three years
Pre-Project Scenario Teesta Barrage Project
A vast area of Northern zone suffered from scarcity of water in the dry season as well as in the wet season that affects the crops

Teesta Barrage ProjectChronological Development
The idea of irrigation by diverting the flow of Teesta River was conceived since 1945 during British period and most of the area found suitable for gravity irrigation
During Pakistan period feasibility studies were carried out by M/s Heigh Zinn & Associates (1959-60) & latter by Binnie & Partners(1968-70). They suggested for Surface Water irrigation through Teesta Barrage
After independence of Bangladesh, the Engineers of BWDB and BUET reviewed the previous reports, studies and carried out a detail planning and design of the project

Benefit from Phase-I During Kharif–II irrigation provided to 70,000ha (2006) and during
Kharif-I irrigation provided to 65,000ha (2006 Cropping intensity increased from 180% to 210%. Annual gross
incremental benefit from paddy is ~ Tk.300 crore. Teesta Barrage Project, Phase-1 is now free from flood of Teesta
River. Drainage problems of different part of the project area i.e Naotara Syphon area, Hazarihat, Dhodrar River, Mirkabeel Area Ghugumari River at Kaimari were identified and remedial measures are being implemented.
Due to SW irrigation, GW recharge has been increased significantly creating more opportunity for conjunctive use.
The benefit of the project is going mostly to the poorer section of the society. The socio-economic condition is changing immensely and creating a better living condition of the people.
Women in Development: Demand for labour has been generated due to increase
yield of crop and its preservation. women play a vital role in collecting and processing of
crops. Landless widows and distress women are working as
women labour in embankment/canal maintenance.
Environment: Watershed, reservoir, canals, green crops and the trees
along the dykes bring in positive impact on the climate. A vast land in the northern region of the country was
suffering from desertification but now being transformed into cropland.
The socio-economic condition is changing immensely and creating a better living condition of the people.

Major ComponentsPhase-II
The project is mainly for supplementary irrigation (Kharif–II). During this period sufficient flow is available in Teesta River at the barrage point.
Construction of major infrastructure such as Barrage, Canal Head Regulators, Main Canals completed for whole project.
Cropping intensity within the project area will be increased from 180% to 215 %.
Surface water irrigation is much cheaper, environment friendly and increase soil fertility
Expected Benefits of Phase-II:
Crop production will be increased to 16.64 Lac MT/year, present value of crop is Tk.1399.5 crore.
Development activities in other sectors will also be increased.
Implementation of Phase-II will establish the Teesta water sharing right of Bangladesh
Expected Benefits of Phase-II:
Teesta Barrage Project is one of the major gravity irrigation projects in Bangladesh diverting water from Teesta river by Barrage.
It has already started contributing in poverty alleviation of mass people of the area through accelerated economic growth
The project (Phase-I) been planned, designed and implemented by the local Engineers, Planners, Consultants and Contractors - unique example of self-reliance.
The Nation is proud of this excellent achievement
CONCLUSION
Where ever feasible surface water based irrigation
project should be taken up – as surface water is comparatively cheaper, environment friendly and increase soil fertility.
Teesta water is enough to provide supplemental irrigation in entire Phase-II area.
CONCLUSION
THANK YOU
for being with us.
