It is easy to make clean water dirty but it is difficult to make dirty water clean again.

However, people try very hard to do so at the Thị Nghè Canal in Ho Chi Minh City.

They ride exercise bicycles that are attached to machines that can clean the water.

An hour of cycling can clean one cup of water!

HCM CITY – Residents living near the polluted Nhiêu Lộc – Thị Nghè Canal in HCM City are performing a public service as they take turns spinning the wheels of a bicycle system designed to clean the canal’s dirty water. 

The four bikes, connected to generators and a water filtration system, are part of a campaign sponsored by Bridgestone Tyre Sales Việt Nam called “Keep River and Lakes Clean for a Better Life” (“Giữ hồ sông xanh cho cuộc sống an lành”) to raise public awareness about environmental protection.  

Local resident Ngô Tâm, 59, a frequent visitor to the area, told Việt Nam News that he now finally understood how difficult it was to purify raw water.

“It’s a lot easier to pollute than to purify. I was riding intensely for over an hour and only a cup of water was purified,” he said. “We can’t clean the entire canal with four bikes, but at least we’ve done something for the environment.”

Located near the bikes are several standard exercise bikes used by families in the neighbourhood. However, they haven’t garnered as much interest as the new “water-purifying bike system”.  

The bike system works this way: As riders move the pedals, the generator is activated, which produces power that pumps water through a filter tank filled with sand, gravel and active charcoal, which absorbs pollutants and purifies the contaminated water.

The clean water is then released back into the canal.

Lê Minh Ánh Xuân, 51, who has used the new bike system, said she felt good about doing her part in protecting the environment.

“I know that I can’t do much, but I feel proud that I can contribute to society,” she said.

Adults as well as children are enthusiastic about the bike system.

Many parents said the bikes not only helped their kids engage in an active lifestyle but also educated them about social responsibilities.

“I love it when I see the clean water released into the canal,” said 11-year-old Nguyễn Ngọc Anh. “It motivates me to do something meaningful in the future, too!”

As the bike system appears to be a hit with local residents, many families agree that similar bikes should be set up around the city to spread the positive environmental message.

“This project shouldn’t end up as a fad, but become part of a green lifestyle that everyone should embrace,” Tâm said.

Trương Văn Định, 48, a resident in the neighbourhood, suggested that the city authorities make the bikes slimmer and attach higher-quality locks to prevent theft.

Chế Đình Lý of the city’s Institute for Environment and Resources told the Tuổi Trẻ News newspaper that, because of the limited city budget, city authorities could seek funds from private investors to promote the project.

Investors, for example, could advertise their products or services on the cycling machines, he said.  

Begun in April, the “Keep River and Lakes Clean for a Better Life” campaign aims to stress the importance of clean water to people’s daily lives and encourage citizens not to throw litter and other items into canals and rivers.

Besides the water-purifying bike system, Bridgestone Việt Nam has organised other environmental protection activities, including clean-up of canals and collection of rubbish in rivers. – VNS

GLOSSARY

Residents living near the polluted Nhiêu Lộc – Thị Nghè Canal in HCM City are performing a public service as they take turns spinning the wheels of a bicycle system designed to clean the canal’s dirty water. 

Residents of a place are people who live there.

To perform a public service means to do something that is useful to other people, not just to yourself.

The four bikes, connected to generators and a water filtration system, are part of a campaign sponsored by Bridgestone Tyre Sales Việt Nam called “Keep River and Lakes Clean for a Better Life” (“Giữ hồ sông xanh cho cuộc sống an lành”) to raise public awareness about environmental protection.  

Generators are machines that make electricity.

A water filtration system is a system that separates dirt and other unwanted things from water.

To raise public awareness about something means to make people know more about it.

Local resident Ngô Tâm, 59, a frequent visitor to the area, told Việt Nam News that he now finally understood how difficult it was to purify raw water.

A frequent visitor to a place is someone who often visits there.

To purify raw water means to take water that is untreated – such as water found in a river – and make it good enough for people to use.

“It’s a lot easier to pollute than to purify.”

To pollute water means to put dirty things into it.

“ I was riding intensely for over an hour and only a cup of water was purified,” he said.

To ride intensely means to do so very powerfully.

However, they haven’t garnered as much interest as the new “water-purifying bike system”.

Garnered means collected. 

 “This project shouldn’t end up as a fad, but become part of a green lifestyle that everyone should embrace,” Tâm said.

A fad is a fashion that is popular for a while and is then forgotten about.

To embrace a green lifestyle means to take up living in a way that is environmentally friendly.

Chế Đình Lý of the city’s Institute for Environment and Resources told the Tuổi Trẻ News newspaper that, because of the limited city budget, city authorities could seek funds from private investors to promote the project.

A budget is a plan on exactly how to spend a certain amount of money. A city budget is a budget for a city. A limited city budget is a city budget that does not involve an endless amount of money. In other words, there is SO much and NO MORE!

Investors are people who spend money on something in the hope of making more money from it.
