The only city in China that is not afraid of flooding is Qingdao. As we all know, Qingdao is a city that is not afraid of heavy rains, so it is called "the only city in China that is not afraid of flooding" by netizens across the country. Many people like to use Victor Hugo's famous saying "The sewer is the conscience of a city". This description is a compliment to Qingdao’s sewerage system.

Qingdao rarely suffers from waterlogging, mainly due to the natural geographical environment, mild climate, hydrology and perfect drainage system. Qingdao is a coastal city integrating mountains, sea and city. This terrain allows rainfall to quickly flow into the sea, and extreme weather such as typhoons rarely occurs. In addition, Qingdao has invested heavily in urban pipe networks.

Qingdao’s water resources

The Qingdao sea area has many harbors, winding coastlines, vast tidal flats, and fertile water quality. It is a place where a variety of aquatic life thrives, including Jiaozhou Bay, Laoshan Bay and T-shaped Bay. The nutrient salt content in the waters at the mouth of the bay is high, the supplementary sources are sufficient, the amount of strange bacteria is several times or even thousands of times higher than that in the continental shelf area or ocean area, and the organic matter content in the water is high.

Especially the sandy shore section of Jiaozhou Bay is an excellent sea area for the development of shellfish and algae cultivation. The sea area is also rich in plankton, benthic organisms, economic invertebrates, intertidal algae and other resources.
