我国西北地区的新型城镇输水工程通常具有管线长、扬程高、流量相对小、沿线地形起伏点多、供水保证率要求高、户外水锤防护措施需充分考虑西北地区冬季寒冷天气的影响等特点。陕北某新型城镇输水工程位于毛乌素沙漠南缘，通过水库坝内预埋钢管引水至加压泵站的进水池，然后从进水池中取水，通过水泵加压，沿右岸河床输水至下游1.26 km处并沿垂直等高线爬坡至坡顶，再沿道路输水至水厂，管线采用了钢管和球墨铸铁管两种材质，输水线路总长10.5 km，沿线起伏较多，设计扬程157.7 m。依托该工程介绍了西北地区长距离高扬程多起伏输水工程的几个选型设计关键技术问题，可供类似输水工程的选型设计参考。

The water transfer projects of the new town in northwestern China usually have the characteristics of long distance, high lift, relatively small flow, many fluctuations along the line, high water supply guarantee rate, and outdoor water hammer prevention measures should consider the impact of cold weather on the Northwest China. The water transfer project of a new town in northern Shanxi is located in the southern edge of the Maowusu Desert. The water is pumped into the inlet pool of the pressurized pumping station through the pre-buried steel pipe in the dam, and then the water is taken from the inlet pool, pressurized by the water pumps, water is transported along the right bank bed to the downstream, and climbs along the vertical contour line at 1.26 km to the top of the slope, and then transports water along the road to the water plant. The pipeline is made of steel and ductile iron. The total length of the water pipeline is 10.5 km, with many fluctuations along the pipeline and the design water head is 157.7 m. Based on the project, the key technology of selection design for long-distance high-lift and multi-fluctuation water transfer projects in the northwest region are introduced, which can be used as reference for selection design of similar water transfer projects.
