Zhangzhou, Fujian: Everyone Need Do Their Job to RUN the Township Sewage Treatment Plant

Secondary and tertiary pipe networks are not matched with each other, and sewage cannot enter; sewage concentration is not enough, the sewage treatment facilities perform poorly……. in recent years, a lot of villages and towns sewage treatment facilities became difficulty construction and operation. And in some villages and towns, sewage treatment facilities idle for years. The sewage treatment facilities of township for prevention and treatment of rural domestic sewage pollution to improve river water quality is of great significance in such aspects, how to make its effective operation becomes a problem to be solved.

Since 2017, Zhangzhou City to implement the rural sewage treatment PPP operation mode, enterprise operations, government supervision of their respective functions, increase the construction of township sewage facilities and supporting pipe network, township sewage facilities operating to a good trend has emerged.

"The earliest township sewage treatment facilities in Zhangzhou were the towns of Jiaoei, Yanxi, Jingcheng, Duxun, Fengshan, Changshan and so on. In 2014, in order to improve the pollution situation in key river basins, the city of Zhangzhou was one step ahead of the construction of sewage treatment facilities in 36 townships within 1 km of the Kowloon River Basin and the Tulou Protected Area. Guo Xiaochuan, head of the village construction section of the Zhangzhou Municipal Housing and Urban-Rural Development Bureau, told reporters that the investment in sewage treatment facilities is very large, and the construction costs of the supporting pipe network are frighteningly high. "The funding ratio for the construction of the plant and the pipe network is at least 1:5. That is, the investment plant RMB 10 million, pipe network supporting at least RMB 50 million. The same 1 km pipe network, townships collect much less sewage than cities. As a result, enough sewage can only be collected through longer pipes or more complex processes. Guo Xiaochuan said that the grass-roots financial resources are weak, so it is very difficult to improve the sewage network.

The construction of the pipe network lags behind, coupled with the complex situation of "Rain pollution is not separated with sewage", which makes the sewage collection rate low. The outside world often mistakenly believes that the amount of sewage to come is small, sewage treatment plant costs are reduced. But the opposite is true. No matter how much water comes in, the labor, electricity, pharmaceutical and other costs of sewage treatment plants have not changed. More importantly, the bacteria in the treatment plant survive on a certain concentration of sewage. "If the sewage concentration is not enough, it will cause a large number of bacteria in the treatment plant to die, and it will be time-consuming and expensive to re-cultivate the bacteria. So some processing plants would not running. Sewage treatment facilities can be used for more than a decade, but if not running, it will break down in two or three years. "A sewage industry insider said.

In addition, the layout of township sewage treatment facilities scattered, small scale, high cost, some places did not arrange special funds or powerless to afford it, it is difficult to get stable funds for the operation and maintenance of township sewage treatment facilities, the grass-roots professional management team, technical personnel can’t guarantee the source of pollution interception work, and also affect the operation of township sewage treatment facilities. No money, no manpower, no water, no methods to management, then become the four "Roadblocks" of the project.

" No matter how difficult it is, we must be brave to make it!" Guo Xiaochuan said that in 2017, the three-year battle for rural sewage waste in Zhangzhou City began, with plans to take three years to achieve full coverage of township sewage treatment facilities.

 “There are hundreds of townships in Zhangzhou, and the situation is very different. Townships with large populations may establish sewage treatment plants. With a small population, even if sewage treatment plants are established, it is difficult to maintain operations, with the use of artificial wetlands or miniaturized integrated facilities.” Guo Xiaochuan said, such as these townships like Guokeng, Chaoyang, Shiting, Jinfeng, it can be built into the urban sewage network for treatment.

This year alone, 13 counties and urban areas in Zhangzhou launched 16 rural sewage treatment PPP projects, with a total investment of RMB 6.3 billion. Where does the money come from with such high construction and operation costs? The answer is the PPP model of sewage treatment introduced by the city of Zhangzhou. Each county will be township sewage treatment plant into a package or two packages, by the way of franchising by enterprise construction and operation, the government and social subjects to establish a "Benefit Sharing, Risk Sharing, Full Cooperation" of the community relationship. Fort this reason, the government's financial burden was reduced, the social subject's investment risk is reduction.
