Why is tap water drinkable in developed countries but not in China? On the surface, it's because every part of China is dirty, from the source to the pipes. But in reality, it's because of fatal flaws in China's water industry.

So Zhuzhou's partners should not easily imitate the American and Korean dramas in which the hero unscrews the faucet and tilts his head to drink, it is very easy to drink a bad stomach...

The following chart, in accordance with the data produced by the U.S. Centers for Disease Control and Prevention, labeled countries tap water quality conditions, the blue area indicates that you can drink directly, the brown area is not allowed, the whole of Asia is a piece of brown, only Japan and South Korea, Singapore is a piece of blue.

1, why Japan tap water can be directly drinkable?

Because the Japanese government's testing of tap water is very strict, requiring standards higher than bottled mineral water.

In Japan, the tap water safety standards are in accordance with the Waterways Act to the implementation of the mineral water standards are in accordance with the Food Sanitation Law to the implementation of the Waterways Act standards are more stringent than the Food Sanitation Law, in the specific standards, cadmium content, for example, the Food Sanitation Law, the requirements of the law does not exceed 0.01mg per liter, while the requirements of the Waterways Act is not more than 0.003mg per liter.

In Japan Pollution of tap water and water sources is punishable by imprisonment for not less than six months and not more than seven years.

The Japanese government also attaches great importance to the promotion and publicity of tap water, and often joins forces with regional water companies to advertise in order to get people to drink tap water directly. For example, these old men from the Tokyo Waterworks Bureau, pictured below, drink directly to the public right in front of the camera.

Of course, there are plenty of Japanese who hold the view that tap water is "unsafe" and "unpleasantly smelly".

Survey data released by the Japanese government showed that:

While Japan's tap water can be directly consumed, but only 37.5% of all Japanese people directly drink tap water, and 32% of people in the faucet with a water purifier and then drink the water, buy mineral water to drink the people accounted for 29.6%, the tap water boiled to drink the people accounted for 27.7%. This survey is multiple choice, so several choices add up to slightly more than 100%.

2. Why can't China do this?

July 1, 2012 onwards, the central government on the mandatory implementation of the latest drinking water standards, with international standards, the indicators reached 106, and the world's most stringent water quality standards - the EU water quality standards are basically the same, if the strict implementation of this standard, the tap water in the factory is ready to drink directly, but the The actual situation is not optimistic, I personally believe that the following two points are the main reasons affecting the quality of tap water in China.

1. Drinking water standards lack of real effective regulatory and punitive measures

China's water plants, most of the self-test self-test, and did not establish a local water plant independent of the professional water quality monitoring organizations, there is no "third party" water quality monitoring, water quality indicators of self-testing, naturally, all are The water quality indicators measured by the tap water plant are naturally "qualified".

There are also no substantial penalties for non-compliant water plants.

2, secondary pollution

Currently there are two ways of supplying tap water, one is the direct pipeline transmission, and the other is the water supply from the cistern (water tower).

Tap water needs to pass through a very long pipeline to be transported to the community, in the process of tap water transmission, because the official website aging, leakage, internal bacterial growth and other reasons, resulting in secondary pollution.

China's waterworks are generally managed by the city's construction department, cisterns (tanks) and other secondary water supply facilities theoretically belong to the health sector, the health sector is usually unable to regulate the community property should usually be responsible for the care, monitoring, but the domestic property is very unprofessional, there is no sense of responsibility, so the water tanks are often cleaned up not in place, resulting in the secondary contamination of tap water.
