Is there really a package with drawings and repair tools at regular intervals in Qingdao sewer built by Germans?

Some people say that although the sewer is invisible, it can test the conscience of the city at a critical moment. According to legend, Qingdao, the only city that is not afraid of floods, has a very large sewer system. Recently, however, there are rumors that Qingdao's perfect drainage system benefits from German manufacturing. The sewer built in Germany 100 years ago can still be used now. Every once in a while, there is an oiled paper bag containing drawings, and the spare parts are still brand-new.

Feelings helped us do good things when Germany came to colonize? Such meticulous work is like hanging the sewer system of the whole country.

Is that really the case? Of course not!

1898, the Qing government was incompetent. After signing the unequal treaties, Germany thought it could occupy Qingdao, so it was willing to spend a lot of money and energy to build it in Qingdao. At that time, Germany had very mature experience in sewer construction, and its technology was world-class. They treat domestic sewage and rainwater separately, so that when it rains heavily, the rainwater will not be blocked by domestic garbage. Germany has also built a number of culverts, which are covered with ceramics, and rainwater can soon be discharged into the sea along the sewers.

For sewers, their construction technology is first-class, but it is only built around the concession where they live, which improves their living standards. For their domestic sewage, it has always been directly discharged into the areas where Chinese people live, which has led to the Chinese areas becoming stinking ditches, and the people of Qingdao have suffered greatly.

After the founding of New China, Qingdao government immediately began to rectify the pollution problems caused by German residential areas. Later, the Qingdao government borrowed German technology. By the 1990s, Qingdao had a perfect drainage system, and they also extended this technology to other provinces and cities in China. At present, the total length of Qingdao sewer is 3000 kilometers, and the section built in Germany only accounts for a small part.

More than a hundred years later, the sewers built in Germany are still in use, but the Qingdao government has renovated them, and many sewers have even changed pipes. And the sewer is full of cement, how can you dig into the oil paper bag? It's impossible to think about it.

However, whenever it rains in summer, the Qingdao sewer built in Germany will be mentioned again by netizens. The main reason is that the drainage system in the city is too poor. When it rains heavily, it will cause floods, which will seriously affect people's lives. The rumor of German sewer just poked everyone's inferiority complex and foreign worship psychology, which made them downplay this humiliating history.

However, in retrospect, German colonists lived in Qingdao for 100 years ago. Instead of building tall buildings, they built sewers. Even today, how many cities in China will do such seemingly unproductive things when they are engaged in construction?
