Bangladesh is a riverain country. About 800 rivers flow in the heart of this beautiful country constituting a water way of total length around 24,140 km. Most of the country’s land is formed through silt brought by the rivers. But due to climatic change, global warming and man made disasters small rivers are all ready dead , mediums are on death ill and maximum big rivers are fighting to survive. The Buriganga river has served the central artery to economic life in Dhaka for centuries. In addition to the commercial benefits the Buriganga has offered Dhaka city a constant water supply, ground water recharge, recreation and fisheries as well as support for agricultural, sanitation and industrial purposes. The indiscriminate dumping and industrial waste combined with the failure of authorities to enforce existing regulations to protect the ecological health of the river has aggravated the situation to the point where Buriganga river is dying biologically and hydrologically.
