The Buriganga River in Bangladesh has become heavily polluted over the past few decades. Once a source of drinking water and important for trade, the river is now close to biological death due to pollution from Dhaka's growing population. Sewage, waste from factories and tanneries, and oil spills have turned the river black and killed all fish. Solutions are needed such as wastewater treatment plants, dredging the riverbed, and controlling pollution from industries. With concerted efforts, it may be possible to restore the river as was done with London's Thames River.
BURIGANGA RIVER of Bangladesh
- 1. BURIGANGA RIVER OF BANGLADESH Presented by: Afrida Jahan Choudhury Washia Zaman Mohamed Abdulkader Mohamed Shafi’I Ali Adan Jinia Nowrin
- 2. 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 polythenes 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.
- 3. INTRODUCTION (CONTD..) 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
- 4. 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.
- 5. POLLUTION The Buriganga River in Dhaka has become heavy polluted from sources such as waste flowing into the river, oil spills from boats and building structures appearing on the river banks. The Buriganga river is afflicted by the intolerable 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 major pollutants.
- 6. 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.
- 7. 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.
- 8. POLLUTION SCENARIO (CONT…) o 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.
- 9. 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.
- 10. REMEDIAL MEASURE (CONT…) 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.
- 11. CONCLUSION River is a vital natural resource which water is essential for a multiplicity of purposes One of our inspiration or ideal could be the famous River Thames in England. This had a worse scenario than our Buriganga. No one can imagine how it was during the 20th century. The River Thames was named ‘The Great Stink’ in 1858 as all the sewage line was connected with the River Thames. Environmental officials now say the Thames is the cleanest. It took 20 years of double efforts to complete and allow wildlife back into river. And now the River Thames water is supplied for drinking water and there was a expansion of bankside development which resulted in an economical gain as well.
- 12. CONCLUSION (CONT…) 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.
