This thesis provides a water infrastructure planning strategy based on an analysis and evaluation of the present situation, which more effectively integrates the current scenario of rural development while adjusting to the trend of population development and resource allocation in rural China. In the north-central area of Shaanxi Province, 25 villages were chosen for field study in order to get a comprehensive grasp of the population and land-use conditions. The size and population of the area needing sewage and drainage infrastructure are estimated by the projection of rural population decline and the projection of rural building land scale and land-use adjustment. On this basis, sewage and drainage facilities are subsequently planned, including the contents of a three-compartment septic tank, sedimentation tank, sewage network, and ecological treatment tank. This type of water infrastructure design may not only enhance the living environment of the region but also efficiently address the issues of water collection and agricultural irrigation in the desert tablelands, enabling the efficient use of resources and sustainable growth of the community.
A new wastewater drainage model for coordinated development is designed in this study.
The wastewater drainage model is to solve the problem of scattered villages and limited construction funds.
According to the regional water endowment and industrial characteristics, the model can draw up corresponding water allocation schemes to balance the social, economic, and environmental benefits.
