东山供水工程是“山西大水网”重要骨干工程之一,是我省“十二五”期间为提高全省水资源配置能力而重点建设的互连互通工程。工程从晋中东部地区水资源相对丰富的左权县、榆社县及长治市武乡县调水到晋中南部的太谷县、祁县、平遥县、介休市和灵石县,补充调入区工、农业用水。工程输水线路全长255 km,其中隧洞长75 km,压力管线长180 km,沿线设岩南沟、小寨及关河三座泵站,最大设计扬程为279 m,总装机容量18150 kW,年总供水量11219万m~3,工程等别为Ⅲ等,建设总工期四年。通过实施工程可有效调配我省水资源丰枯不均,保证水资源可持续开发利用,为晋中西南部经济社会发展提供强有力的水支撑,具有重要的战略意义。
Dongshan Water Supply Project is one of the important backbone projects of Shanxi Dashu Network and an interconnection project focused on improving the province’s water resources allocation capability during the 12th Five-year Plan.

The length of water transmission line of the project is 255 km, of which, the tunnel is 75 km long and the pressure pipeline is 180 km long. Three pumping stations, namely Yannan Ditch, Xiaozhai and Guanhe, are located along the line with a maximum design lift of 279 m and a total installed capacity of 18150 kW. The total annual supply of 112.19 million m ~ 3, the project is equal to Ⅲ and so on, the total construction period of four years. Through the implementation of the project can effectively allocate uneven abundance of water resources in our province to ensure the sustainable development and utilization of water resources for the economic and social development in southwest of Jinzhong to provide a strong water support has important strategic significance.
