3. INTRODUCTION
• Buriganga river is a stream In Dhaka
division, Bangladesh with the region font
code of Asia Pacific.
• In the 20th century the water table and
river became polluted by polyethene's and
other hazardous substances from
demolished buildings near the river banks.
• The water of the Buriganga is now so
polluted that all fish have died, and
increasing filth and human waste have
turned it like a black gel. Even rowing
across the river is now difficult for its smell
so bad.

4. INTRODUCTION
• This vital river however has become extremely polluted and close
to biological death for several reasons.
• For this, the sources and occurrences of river pollution should be
studied carefully and deserves an urgent adoption and
implementation of necessary measures to recover the natural
ecosystem of the river sand to restore the water quality of the
river Buriganga.

6. BURIGANGA RIVER IN BRIEF
• Buriganga River a tide-influenced river
passing through west and south of Dhaka
City. There is a traditional story behind
naming it. In ancient times one course of
the ganges used to reach the bay of
Bengal through Dhaleshwari. This course
gradually shifted and ultimately lost its link
with the main channel of the Ganges and
was renamed as the Buriganga.
• The Buriganga is of great economic
importance to Dhaka. It provides river
connection by launch and country boats.
Large steamers can no longer ascend the
river in the dry season.

7. BURIGANGA RIVER IN BRIEF
• The Buriganga originated from the Dhaleshwari near Kalatia. Its average width
and depth are 400m and 10m respectively. This river is only 27 km long. The
turag has joined the Buriganga at Kamrangirchar of Dhaka City. In fact, the
main flow of the Buriganga comes from the Turag. It meets with the
Dhaleshwari at munshiganj. The present head of the Buriganga near
Chhaglakandi has silted up and opens only during floods, but the lower part
is still open throughout the year.
• Water pollution in the River Buriganga is as its highest. The most significant
source of pollution appears to be from tanneries in the Hazaribagh area. In
the dry season, the dissolved oxygen level becomes very low or non-existent
and the river becomes toxic

9. HISTORY OF BURIGANGA RIVER
• In the distant past, a course of the
Ganges river used to reach the Bay of
Bengal through the Dhaleshwari river.
When this course gradually shifted and
ultimately lost its link with the main
channel of the Ganges it was renamed
the Buriganga. It is said that the water
levels during high and very high tides in
this river astonished the Mughals. In the
20th century the water table and river
became polluted by polythenes and
other hazardous substances from
demolished buildings near the river
banks.

10. HISTORY OF BURIGANGA RIVER
• The course of the Padma, as the
main course of the Ganges is known
in Bangladesh, changed considerably
during the period 1600 to 2000 AD.
It is difficult to trace accurately the
various channels through which it
flowed, but the probability is that it
flowed past Rampur Boalia, through
Chalan Beel, the Dhaleshwari and
Buriganga rivers, past Dhaka into the
Meghna estuary.

12. POLLUTION OF BURIGANGA RIVER
• The Buriganga is economically
very important to Dhaka.
Launches and country boats
provide connection to other
parts of Bangladesh, a largely
riverine country. When the
Mughals made Dhaka their
capital in 1610, the banks of
the Buriganga were already a
prime location for trade. The
river was also the city's main
source of drinking water.

13. POLLUTION OF BURIGANGA RIVER
• Today, the Buriganga river is
afflicted by the noisome problem
of pollution. The chemical waste of
mills and factories, household
waste, medical waste, sewage, dead
animals, plastics, and oil are some
of the Buriganga's pollutants. The
city of Dhaka discharges about
4,500 tons of solid waste every day
and most of it is released into the
Buriganga According to the
Department of Environment, 21,600
cubic metres of toxic waste are
released into the river by the
tanneries every day.

14. POLLUTION OF BURIGANGA RIVER
• More than 60,000 cubic of toxic waste, including textile dying, printing,
washing and pharmaceuticals, are released into the main water bodies
of Dhaka every day.[citation needed] According to the Dhaka Water and
Sewerage Authority (WASA), about 12,000 cubic metres of untreated
waste are released into the lake from Tejgaon, Badda and Mohakhali
industrial areas every day. The waste mostly comes from garment
washing and dyeing plants. Textile industries annually discharge as
much as 56 million tonnes of waste and 0.5 million tonnes of sludge.
Sewage is also released into the Buriganga. A newspaper article from
2004 indicated that up to 80% of Dhaka's sewage was untreated.
Because of Dhaka's heavy reliance on river transport for goods,
including food, the Buriganga receives especially high amounts of food
waste since unusable or rotting portions of fruits, vegetables, and fish

16. BURIGANGA BEFORE 40-50 YEARS
• During 1610 Buriganga was a prime
location for trade for Mughals,
made Dhaka their capital.
• Buriganga was once the main
source of drinking water for Dhaka
residents.
• The river was crystal clear.
• In the past Buriganga was
economically
very important to Dhaka.

17. POLLUTION SOURCE
• Pollutants are mainly generated in
and around the city through
domestic, commercial and industrial
activities.
• Wastewater and sewage generated
in the city are carried into the river
system through numerous outlets.
The river is affected along its course
by both point and nonpoint sources
of pollution.

19. POLLUTION SCENERIO
• Buriganga river extremely polluted and it is close
to biological death for several reasons. The
tremendous increase in population (12 million) of
Dhaka City over the last three decades has created
enormous environmental problems. Human
sewage coupled with municipal garbage, the
disposal of solid waste and drainage problems are
the main reason.
• River depth decreasing due to sludge deposition
hence affecting the navigation.
• Tanneries of Hazaribagh, chemical industry of
Tejgaon and many other factories poisonous
wastes are falling down in the river without any
treatment.

20. POLLUTION SCENERIO
• Human excreta’s and other waste
from the floating vessels are
spilled. These wastes contaminate
the river water affecting its
aquatic life and ecological health.
• From the launches and engine
vessels in Sadarghat and dockyard
areas, there are discharges
kerosene and Mobil oil.

22. REMEDIAL MEASURE
• Environmental degradation is widely
observed but the key issue is to do
something for the ecological
restoration of the environment. Early
implementation of efficient
management practices will save the
Buriganga River. It has been seen that
this river has considerable pollution
assimilation capacity which provides
considerable opportunity for
improving water quality.

23. REMEDIAL MEASURE
• It is essential to make provision for protection and improving water
quality of the Buriganga river to sustain the ecosystem in this river
and overall environment of the Dhaka city.
• Hazaribagh tanneries are responsible for causing pollution in the
Buriganga river by the contribution of toxic and persistent
pollutants, for that an Effluent Treatment plant (ETP) should be
established without delay.
• Proper dredging of the existing river and removing non
degradable matters from the river bed.

24. CONCLUSION
• From this we can learn that it is not impossible to
bring back our Buriganga to its life.
• Buriganga River may bring many benefits to us such
as boating, fishing, tourism, transportation, industry,
power stations and makes people enjoy many popular
and interest sports.
• There was a campaign on "Save Buriganga, Save Lives”
by government to have a positive step to save
Buriganga.
