1 ASIA WATER CYCLE SYMPOSIUM 2016 ICHARM S CAPACITY BUILDING: CHALLENGES AND FUTURE PROSPECTS REGARDING WATER-RELATED RELATED ISSUES IN BANGLADESH Md. Khairul Islam Executive Engineer, Bangladesh Water Development Board, Dhaka, Bangladesh. Date : March 2, 2016 TOKYO UNIVERSITY

2 TheOrganizationIworkfor CONTENTS OF THE PRESENTATION Challenges my organization is facing currently regarding water-related issues My current activities and responsibilities My ambitions(expectations, prospects) for the future for contributing to water-related issues in my country

3 BANGLADESH WATER DEVELOPMENT BOARD (BWDB) A statutory body under the Ministry of Water Resources, Government of Bangladesh.

4 BANGLADESH WATER DEVELOPMENT BOARD (BWDB) Development of rivers, flood control, drainage, surface irrigation By Constructing dams, barrages, reservoirs, embankments, regulators Improvement of water flows By dredging, re-excavation and de-siltation of water channels. Protection of places of historical and public importance By river training and river bank protection works Flood forecasting and warning By Flood Forecasting and Warning Center Development of water user s association By training and participating in all project phases.

5 BWDB CHALLENGES Flood: A common phenomenon in Bangladesh Urban Drainage Congestion: due to Backwater effect of river flooding, Hindrance by infrastructures River Bank Erosion: A major impact of river flooding at the time of recession Inundation: due to placement of dam or other intervention (fringe area in the Kaptai reservoir). But often no distinction is made between flooding and inundation. Water Logging: due to absence of adequate drainage route (Beel Dakatia). River Pollution: mainly due to industrial effluent, domestic sewage, encroachment 1996

6 CURRENT ACTIVITIES AND RESPONSIBILITIES Improvement of water flows of Buriganga river By dredging, re-excavation and de-siltation of water channels. Buriganga river pollution around Dhaka city mainly due to industrial effluent, domestic sewage, encroachment.

7 BURIGANGA RIVER RESTORATION PROJECT Background Water flow declined significantly Water became polluted Posing serious threat Doesnotreceiveflowsfromthefeederriver Nearly no flow condition during dry season. To meet the above issues and challenges the Project has been taken up for achieving sustainable development by water diversion of Jamuna river.

8 BURIGANGA RIVER RESTORATION PROJECT Jamuna (Lower Brahmaputra) Offtake of New Dhaleswari: 245 m3/s New Dhaleswari Pungli Bangshi Tongi Khal: 19 m3/s Turag-Tongi Khal offtake: 162 m3/s Turag Lakhya: 16 m3/s Dhaka Buriganga Buriganga: 141 m3/s

9 BURIGANGA RIVER RESTORATION PROJECT Objective of the Project Specific objectives: maintain dry season minimum flow for Improving water quality Meeting navigational depth At the peripheral rivers of the Dhaka city. Others Irrigation and fisheries development. Improvement of overall economic, social & environmental condition. Unauthorized encroachment control along Buriganga River

10 BURIGANGA RIVER RESTORATION PROJECT Main Physical component of the project: Dredging/re-excavation of Rivers Stop Log Sand barrier Flush sluice Training Bank Sediment Basin km 1 no. 1 no. 300 m 1 no. Project Cost: Tk million

11 BURIGANGA RIVER RESTORATION PROJECT Challenges New Dhaleswari off-take been silting up regularly Solution: Off-take management by different structures Dredging may damage foundations of 22 bridges Solution: Re-construction and foundation treatment Reduction of planned dredging section Illegal Encroachment along the river system

12 FUTURE PROSPECTS TO WATER-RELATED RELATED ISSUES Water Resources Management Comprehensive river management development for all major rivers Rationalizing flood management systems Increasing water use efficiency in surface and ground water irrigation Increasing availability of surface water Ensuring effective stakeholders participations Institutional development and inter-institutional management

13 Disaster Risk Reduction FUTURE PROSPECTS TO WATER-RELATED RELATED ISSUES Development of a reliable long-term prediction of river bank erosion Reliable predictions of extreme climatic events Development of a community-based flood forecasting system Environment Improving connectivity between flood plains with the river systems to revitalize water dependent eco-systems Wastewater&waterquality A comprehensive waste water management system Conducting water quality monitoring regularly and rigorously

14 Thank you for all of your attention
