Daily disposal capacity

Note: For Tibet no data on sewage disposal capacity were available.
In a modern society,
functioning sewage systems are an essential infrastructure for urban
areas. As the figure displays, China's provinces have rather different
standards in terms of sewage system capacity per urban inhabitant.
Especially the remarkably short network of sewer pipelines per 10,000
inhabitants in Qinghai, Shaanxi, and Shanxi should be a reason for
concern. The largest network of sewer pipelines per 10,000 inhabitants
was reported from Tianjin, Hainan, and - surprisingly - from Tibet.
