类似地，2012年，中国住房和城乡建设部报告说，尽管647个城市中的640个以及73%的农村地区拥有废水处理设施，但377处一年内建成项目达不到国家要求，平均运行效率还不到60 % 。
Similarly, China’s Ministry of Housing and Urban-Rural Development reported in 2012 that while 640 of 647 cities and roughly 73% of counties had wastewater-treatment facilities, 377 plants built in the course of one year did not meet national requirements, and that the average operating efficiency was less than 60%.
