�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.

� Water Logging: due to absence of adequate drainage route (Beel Dakatia).

� River Pollution: mainly due to industrial effluent, domestic sewage,

encroachment

BWDB CHALLENGESBWDB CHALLENGESBWDB CHALLENGESBWDB CHALLENGES� Flood: A common phenomenon in Bangladesh

1996

� 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.

CURRENT ACTIVITIES AND RESPONSIBILITIES CURRENT ACTIVITIES AND RESPONSIBILITIES CURRENT ACTIVITIES AND RESPONSIBILITIES 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.

BURIGANGABURIGANGABURIGANGABURIGANGA RIVER RESTORATION PROJECT RIVER RESTORATION PROJECT RIVER RESTORATION PROJECT RIVER RESTORATION PROJECT � Background

�Water flow declined significantly

�Water became polluted � Posing serious threat

�Does not receive flows from the feeder river

�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.

� 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

� Dredging/re-excavation of Rivers 162.5 km� Stop Log Sand barrier 1 no.� Flush sluice 1 no.� Training Bank 300 m� Sediment Basin 1 no.

� Project Cost: Tk. 24440.00 million

BURIGANGABURIGANGABURIGANGABURIGANGA RIVER RESTORATION PROJECT RIVER RESTORATION PROJECT RIVER RESTORATION PROJECT 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
