Shanxi Xian Single Household sewage treatment plant project case
Project Background
This project is located in Goukou Village, Bayuan Town, Lantian County, Xi'an, Shaanxi Province. The development goal of "Green Lantian, Happy Homeland" was defined at the 9th Plenary Session of the 16th Committee of the Lantian County Party, as part of the county’s development plan for the 14th Five-Year Plan period. By 2025, significant progress is expected in rural environmental governance across the city, with agricultural non-point source pollution being preliminarily controlled and continuous improvements in the ecological environment.
The project has contributed to the environmental improvement of 251 administrative villages, with rural domestic sewage treatment coverage reaching over 53%, effectively eliminating large-scale rural black and odorous water bodies. For the period from 2021 to 2025, Lantian County is tasked with completing the rural sewage treatment in 28 administrative villages, and the overall rural domestic sewage treatment coverage in the region is expected to reach 45%.
