Puyang City, the third sewage treatment plant in which place?

Puyang did not hear of the third sewage treatment plant ah, there is a city sewage treatment plant, an oilfield sewage treatment plant, in the second plant that, two plants are there. There is also a second sewage treatment plant under construction, specific that I forget, but can be searched. lz is not the study of the environment? I am also ah. But Puyang's sewage plant is a business unit, the one under construction is a BOT model.
