Is the sewage treatment plant private or state-owned?

Sewage treatment plants are owned by both state-owned enterprises and private enterprises.

In China, the ownership structure of sewage treatment plants includes state-owned enterprises and private investment. Some sewage treatment plants are state-owned enterprises managed by government agencies, constructed and operated by municipal departments, and regulated by relevant laws and regulations. There are also private sewage treatment plants invested and operated by individuals or joint-stock companies. Different types of ownership reflect the mutual participation and cooperation between public and private forces in promoting environmental protection and urban infrastructure development.
