 wastewater. Where conditions permit, urban waste and wastewater treatment facilities and services may be extended to rural areas. For villages with large populations far away from cities and towns, village-level centralized wastewater treatment facilities may be built, and for villages with small populations, household wastewater treatment facilities may be built.
 
In 2017, the “Thirteenth Five-Year Plan for Comprehensive Improvement of the National Rural Environment” highlighted the importance of protection of rural drinking water sources and treatment of domestic waste and wastewater. In 2018, the “Three-Year Action Plan for the Improvement of Rural Living Environment” promoted the treatment of rural domestic wastewater using technologies with low costs, low energy consumption, easy maintenance and high efficiency, and encouraged the adoption of ecological treatment technologies.
 
In 2018, the Ministry of Ecology and Environment and the Ministry of Housing and Urban-Rural Development issued the “Notice on Accelerating the Formulation of Rural Domestic Wastewater Discharge Standards by Regions.” Local governments were encouraged to speed up the formulation of standards for rural wastewater treatment and discharge according to local conditions. In 2019, the “Technical Standards for Rural Domestic Wastewater Treatment Projects” issued by the Ministry of Housing and Urban-Rural Development optimized the specific technical parameters of rural wastewater treatment to adapt to the characteristics of rural wastewater in China.
 
In 2020, a group of three standards were set up, namely the “Standard for Small Domestic Wastewater Treatment Equipment,” the “Evaluation Specification for Small Domestic Wastewater Treatment Equipment,” and the “Technical Regulations for Operation and Maintenance of Village Domestic Wastewater Treatment Facilities.” The first document set out some standardized information for small-scale domestic wastewater treatment equipment, including information registration, design, manufacturing, transportation and installation. The second document set out a standardized evaluation process suitable for China’s national conditions for small-scale wastewater treatment equipment, after considering the experience of such evaluation systems in developed countries and the relevant climatic, geographical and economic conditions of different regions in China. The third document set out the operation and maintenance standards on the operation and maintenance of facilities (collection systems and treatment facilities), operation and maintenance process, operation and maintenance personnel, and operation and maintenance service organization, among other standards.
 
In 2021, the “Guidelines on Accelerating the Modernization of Rural Houses and Villages” highlighted the importance of promoting rural domestic wastewater treatment in accordance with local conditions. Rural areas should adopt small-scale, ecological and decentralized wastewater treatment models and processes, set appropriate discharge standards, and promote local resource reutilization
