Abstract：Based on the water diversion project of Gongyi,this paper discusses the theoretical basis and technical scheme of water resource allocation and water diversion project design.In view of the long-term water shortage problem faced by the central urban area of Gongyi and the five eastern towns,the feasibility of the combined water supply mode of South-to-North Water Diversion and Yellow River water is analyzed,and the optimization design methods for the site selection of water diversion pipelines and the layout of pumping stations are proposed.Analysis of Water Resources Supply and Demand shows that The total water demand of Gongyi in 2025 is 64.129 million m³/a.A combined water supply plan of 20 million m³/a from the South-to-North Water Diversion Project and 22 million m³/a from the Yellow River has been determined.Based on the calculation of the engineering water price and the financial rate of return,the profit water price is 1.292 yuan/m³,and the financial internal rate of return(after tax)is 4.77%.When the water price rises to 1.391 yuan/m³,the return on capital increases to 11.34%,and the economic feasibility is relatively high.The results show that after the completion of the water diversion project,it can effectively enhance the level of urban and rural water supply integration in Gongyi,alleviate the shortage of water supply,and has strong social benefits and economic value,providing a practical reference for similar water diversion projects in the Central Plains region.
