Recycled usage of water can mitigate drinking water crisis
Bangladesh, Dec. 12 -- The rising crisis of drinking water in the country's rural and urban areas can be mitigated by recycling water used in the households and treating domestic and industrial wastes before discharging to the water bodies like rivers and canals, reports.
Experts and environmentalists suggested the authorities concerned to take measures for creating mass awareness to stop misuse of water and also move for a legal step to protect the country's natural resources for sustainable development.
"Water is an indispensable natural resource without which existence of life is impossible," said Dr Mohammed Ataur Rahman, Director of the Program on Education for Sustainability of the International University of Business Agriculture and Technology (IUBAT).
He said on an average, each person in the cities uses minimum 200 liters of water a day and plants absorb millions of liters of water everyday.
Dr Ataur said people are only paying a fraction of the cost of water, as the actual cost of purification and supply to the utilities are much high. "Therefore, we should be very careful about any misuse of water."
He suggested that water taps and showers must not run continuously during bathing and washing of crockery, utensils and clothes. Any leakage of pipes and broken water taps should immediately be repaired or replaced.
Describing sources of water as oceans, underground water, glaciers, lakes, soil moisture, atmosphere vapors and rivers, he said, "
Although water is a non-depletable resource like cosmic or solar energy but fresh water may be regarded as depletable resource because acute shortage of water has arisen in many areas of the world."
"This water shortage is either local or due to pollution", Dr Ataur said.
He said that although the total resources of water of the earth were inexhaustible still a great scarcity of fresh water exists in Bangladesh,where average rainfall is as high as 2000 mm/year and 143,000 cusec of water flows by the rivers.
He said that shortage of water in different areas was becoming a serious problem although Bangladesh is one of the richest countries in the world in fresh water resources.
This shortage, he said, is not for the increasing demand of water for irrigation, and for domestic and industrial uses, but for pollution of water,
depletion of underground water tables and destruction of freshwater reservoirs like haor-baor, beel-jheel, dighi and ponds, and of course, withdrawal of water from the upstream.
"Due to withdrawal of water and disturbance of natural flows, most of the rivers are drying up in the dry season and salinity is increasing in the downstream.
The overall situation of water resources of Bangladesh is very deplorable. This crisis is not only affecting the city lives but the whole agriculture is in a very alarming situation", Dr Ataur said.
The rivers flowing around the cities - Turag, Buriganga, Balu and Sitalakhya - have been turned into open sewage canals with dumping of wastes from the dyeing and garments, tanneries and leather, oil and chemicals, clinics and medicine factories and poultry farms.
