It was once the lifeline of the Bangladeshi capital.

But the once mighty Buriganga River, which flows by Dhaka, is now one of the most polluted rivers in Bangladesh because of rampant dumping of industrial and human waste.

“Much of the Buriganga is now gone, having fallen to insatiable land grabbers and industries dumping untreated effluents into the river,” said Ainun Nishat, a leading environmental expert.

“The water of the Buriganga is now so polluted that all of the fish have died and increasing filth and human waste have turned it into a black gel. Even rowing across the river is now difficult for it smells so badly,” he told reporters.

The plight of the Buriganga symbolizes the general state of many rivers in Bangladesh, a large flat land criss-crossed by hundreds of rivers.

Bangladesh has about 230 small and large rivers and a large chunk of the country’s 140 million people depend on them for a living and for transportation.

A World Bank study said four major rivers near Dhaka — the Buriganga, Shitalakhya, Turag and Balu — receive 1.5 million cubic meters of waste water every day from 7,000 industrial units in surrounding areas and another 0.5 million cubic meters from other sources.

Unabated encroachment that prevents the free flow of water, dumping of medicinal waste and waste of river passengers have compounded the problem, making the water unusable for humans and livestock.

“Unfortunately, all these bad things — encroachment, dumping of industrial waste — occur in full knowledge of the authorities,” said Professor Abdullah Abu Saeed, an eminent campaigner for “Save Buriganga, Save Lives.”

Among the top polluters are dozens of tanneries on the banks of the Buriganga. The government has initiated a move to relocate the tanneries outside the capital, and also asked illegal encroachers to vacate the river.

But environmental groups say they defy such orders by using their political links or by bribing people.

The Buriganga flows by the capital Dhaka, a city of 12 million people, which largely depends on the Buriganga’s water for drinking, fishing and carrying merchandise.

“The pollutants have eaten up all oxygen in the Buriganga and we call it biologically dead. It is like a septic tank,” said Khawaja Minnatullah, a World Bank specialist on environment and water management.

“There are no fish or aquatic life in this river apart from zero oxygen survival kind of organisms.”

Chemicals such as cadmium and chromium and other elements such as mercury carried by the industrial waste are also creeping into the ground water.

“If the pollution is not controlled, we will face a serious health crisis in a year or two or at best three years,” said Minnatullah.

Bangladesh enacted a law in 1995 making it compulsory for all industrial units to use effluent treatment plants in a bid to save river waters from pollution, but industry owners often flout the rule.

“We want the rivers fully dredged, their illegal occupation ended and the laws strictly enforced to prevent abuse of waterways,” Nishat said. “Not many years ago Singapore River was also like our Buriganga. But they cleaned it up and have now turned it into a great resource.”
