The Buriganga River Continuous pollting in Dhaka, Bangladesh


Bangladesh is a riverine country, About 800 rivers including tributaries flow through the country a constituting a waterway of total length 24,140 kiliometer now it is only 8,046 kiliometer depending on season ( reference The Business Environment in Bangladesh, written by Md. Jamal Hossain Buiyan) 16,100 kilometer rivers already grabbed by influential people in the society. This is the actual fact how, Bangladeshi politicians rulling the country last 42 years. Most of country land is formed through silt brought by the rivers.

The Buriganga rivers is economically very important to Dhaka city. Launches and country boats provide connection to other part of Bangladesh. A largely riverine country when the Mughals made Dhaka their
capital in 1610, the banks of the Buriganga rivers were already a prime location for trade. The river water was crystal colour also the city main source of drinking water.

Today Buriganga River is afflicted by the noisome problem of pollution. The chemical waste of mills and factories, households waste, Medical waste, Sewage, dead animals, Plastics, and oil are some of the Buriganga river polluters. The city of Dhaka discharges about 4500 tons of solid waste every day and most of it is released in to the Buriganga River. According to the Department of Environment ( DOE ) 20,000 tonnes of tannery waste including some highly toxic materials are released into the river every day. Experts identified nine industral areas in and around the capital city as the primary sources of river pollution such as Tongi, Tejgaon, Hazaribagh, Tarabo, Narayangonj, Savar, Dhaka Export processing zone and Ghorashal.
Most of the industrial units of these area have no sewage treatment plant or Effluent Treatment plant of their own.
More than 60,000 cubic meters of Toxic waste including Textile dyeing, printing, washing and Pharmacuticals are released in to the main water bodies of Dhaka every day. According to the Dhaka Water and Sewerage Authority ( WASA ) about 12,000 cubic meters of untreated waste are released in to the lake Tejgaon, Badda and Mohakhali industrial areas everyday.

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 in to the Buriganga River. A newspaper article indicated that up to 80% of Dhaka sewage was untrated because of Dhaka heavy reliance on river transport of goods, including food, the Buriganga river receives especially high amount of food waste since unusable or rotting portions of fruits, vegetables,and fish are thrown in to the river.

Nearly 4.0million people of the city are exposed to the consequences of water pollution everyday.
