How long should the water bottle be used?

10 Min Read

Many use the same water bottle for long periods of time, office or home. In using the same bottle everyday, we have an idea that since we are using the bottle alone, there is no possibility of any disease. And if the mouth of the bottle is closed, the organism will not be able to enter. All wrong.

Scientists say that even if a person uses a bottle alone, he is likely to suffer from it. The bottle comes in contact with our hands and mouth while drinking water. Various diseases can be spread by the contact of hands and mouth. Therefore, if not thoroughly washed, it can spread germs.

Besides, the water bottles in which we usually drink water are made of plastic and plastic is very harmful to health. Therefore, even using plastic bottles is seriously harmful to health.

How to use plastic bottles for a long time

On the road-side, the Berol has to come out with water immediately. And a trusty plastic bottle for him. But there are some things to keep in mind when using plastic bottles. Every time you use a plastic bottle, you should wash it thoroughly with soap in hot water. Then dry it well. However, plastic bottles can be used repeatedly.

Plastic bottles should not be used more than once, if used alone, they must be washed thoroughly in hot water to avoid infection and should never be consumed by mouth in a bottle.

According to reports from the World Bank, World Health Organization and UNICEF, about 5 percent of Bangladesh’s population has some source of water. But not all of them are drinkable Thirty percent of people are getting safe or potable water The Joint Monitoring Program of the World Health Organization, UNICEF, and the Government of Bangladesh is said to be the fifth percentile, said Mohamed Jubair Hassan, director of research, planning, and monitoring for the Development Organization for Rural Poor (DORP). He is a member of the South Asian Steering Committee on Sanitation and Water for All Even with this calculation, about 5 percent of the people are not getting enough water, However, water pollution calculates that 3% of people are safe and out of safe water.

Why Water Sources Are Not Safe

Drinking water has been calculated based on the sources considered in the reports But they are now being corrupted 7% of the country has more arsenic than acceptable levels of water For some it is like 25% again

According to a World Bank study published in October last year, e-coli bacteria are the only ones in the pipeline’s water. The same level of bacteria was found in pond water 5 percent of the tube well water was found to be harmful E-coli bacteria are responsible for inflammation of the stomach and intestines

The lack of proper sanitation facilities is also a major reason for this Only 20 percent of the sewerage pipeline in Dhaka is open, while the rest is open 5 Again, only 2% of wastewater treatment is done throughout the country The World Health Organization says the rest of the waste is mainly mixed with water Director of Programs and Policy Advocacy Md. Liaquat Ali tells Deutsche Welled, “There is only one waste treatment plant in the madness of Dhaka. That doesn’t work either So where does this waste go? Go to Burgage and mix in water. ”

Besides, the water is also inaccessible due to salinity in the coastal areas of the country During natural disasters, one third of these areas are at risk of contaminating household water. Md. Liaquat Ali said, “No matter how many calculations are now, more than 5% of the people of Bangladesh are not getting clean or safe water. Because of arsenic and other biological contamination, safe water is to be excluded from the available water. The report of the Joint Monitoring Program 20 says so. ”

Is salt water running out on earth?

We know that water on earth is sufficient But because of widespread farming, excessive water consumption and climate change, water scarcity can occur on our green planet, experts fear.

Two-thirds of the surface area is covered with seawater, even though it is less than one billion trillion liters of water. How is the water shortage on such a planet?

Most of the world’s water but not saltwater, saltwater 1 In fact, only half of the whole water is freshwater; Two-thirds of that freshwater is frozen again in Sumeru, Cumero, and several glaciers around the world. With all the liquid saltwater left, people have to carry out all the work, from drinking water to cooking, to irrigate the fields, to quench the thirst of livestock.

On the downside, it also means that water is a renewable resource that changes in cycles and that the total amount of water on our planet on Earth will remain fairly constant – that is, it will not run out. The question now is whether there will be sufficient water for all people


According to a study by the University of Twente in the Netherlands, about 10 million people in the future may experience severe seizures for at least a month. There are already droughts and widespread water shortages in some regions of the world, such as the Horn of Africa, where millions of people suffer from hunger and disease from year to year. Meanwhile, a UN report has raised concerns that Pakistan may become dehydrated by 2021.

Climate change will make the situation worse Climate change is changing weather patterns around the world, resulting in droughts and floods in some areas. Higher temperatures can also cause drainage by draining the reservoir water Again, mismanagement of water resources can also lead to water shortages Excessive drainage reduces groundwater elevation; On the other hand, rivers and lakes, etc. are either drying up or otherwise their water is becoming inaccessible due to pollution.


In the areas where water is the highest, agriculture comes first About 8 percent of the world’s saltwater costs irrigation and livestock. On the one hand, as modern agriculture has reduced the use of water, on the other hand, due to increasing agricultural intensity and yield, the demand for water in some areas exceeds the local water supply – such as one-fourth of Europe’s tomato production in Spain’s tomato cultivation areas; Therefore, it is normal to have reservoir here

Fresh water in Capital of Dhaka :

Of the water that WASA supplies to the pipeline for Dhaka, 3 percent is underground, while the rest comes from aboveground sources. As a result, the groundwater level is going down Experts fear that there will be a big water crisis in Dhaka in the near future, However, Wasser plans to reduce groundwater use by 20 percent by 2021.

In the capital now there are 7 million 3 million people Of these, 25 percent live in slums They do not have a valid source of 5% water The average daily water requirement of the people in Dhaka is 6 liters but the slum dwellers only get 20 liters.

In a research report titled ‘Dhaka WASA: Challenges and Good Governance Challenges’ by Transparency International Bangladesh (TIB) on April 5, it said that 3 percent of the customers in Dhaka make the company water efficient in different ways. About 5 percent of the consumers drink water by boiling or boiling it An estimated 12 million gallons of gas is wasted every year to make it suitable for drinking water According to the report, 4 percent of consumers complained that the supplied water was refined and 5 percent of the customers smelled bad.

Talking to the city dweller, this is also true Residents of some areas, including Dhanmondi, said, “It is impossible to drink without washing the water. Sometimes it is completely inaccessible to drink There is a bad odor in the water Can’t put on face 1 The kerosene is colored like oil Using this water again, the body is itchy. “
