Domestic waste causes water pollution
Dhaka: Country’s water resources are under serious threats of getting contaminated with indiscriminately disposed domestic wastes, too, besides pollution by industrial waste.
As a result, water is gradually losing quality, polluting air and becoming unsafe to drink, some experts said.
The quantity of polluted water mass is increasing for lack of refining and proper management, and negligence, which is casting bad impact on the entire environment.
Specialists expressed apprehension of terrible situation of water pollution if such waste disposal could not be stopped.
According to a report of Dhaka Environment Program, Bangladesh will have to count financial loss to the tune of 5,110 crore US dollars in next 20 years if the government did not take initiative to stem the increasing water pollution.
Sources said houses have not specific management for keeping domestic garbage. Most of the people do not use safety tank and throw the wastes into drains, lakes and rivers.
Some dump the wastes in low-laying places beside their houses which later get mixed with the river waters flowing down canals or drains after rain.
None does follow the rule of dropping the wastewater into the river after refining and treatment in chemical method. As a result, the domestic wastes are polluting water and environment and fishes of different species are on the way of extinction.
According to chemical analysis, domestic wastes contain poisonous Nitrate, Phosphate and BOD. The wastes need treatment in a specific level after throwing into the river or canal. Developed countries follow Sewerage Water Treatment Plant for waste treatment. But, we do not follow treatment method.
We have only one Sewerage Treatment Plant under Dhaka WASA, having capacity of 1, 20, 000 meter, for refining domestic wastewater. But, the treatment plant could refine only 20 percent wastewater of the city for the scarcity and deficiency of wastewater transmission line.
Deputy Director of Environment Department Dr. Md. Sohrab Ali said that they have sent notice and letter to the persons concerned.
“We have undertaken a master plan for refining wastewater. The problem would be resolved if the master plan could be implemented,” Managing Director of Dhaka WASA Taksim A Khan told bangle news.
Specialists emphasized on increasing people’s consciousness along with the government’s initiative for the wastewater management.
Professor of Environmental Engineering Division of Bangladesh University of Engineering and Technology (BUET) Dr. M Ashraf Ali told banglanews the government has to take project for wastewater refining along with water-supply project.
“The government also has to set up necessary treatment plant otherwise there will be no way to stop water pollution,” he added.
“We have no control on water as nearly 90 percent water comes from out of the country. Under the circumstances, if we don’t stop water pollution, we have to face dire consequences in the near future,” said Professor Md Munsur Rahman of the Institute of Water and Plant Management.
