美国洛杉矶一带,少雨缺水,主要靠两条引水渠道解决水源。一条是从科罗拉多河铺设而来,另一条来自北部的萨克拉门托附近,这两条渠道汇聚在洛杉矶东部约70公里的一个大贮水池。贮水池地势较高,海拔400多米。由于水头较高,所以从贮水池输往各地的管路,都要安装减压阀以保护配管系统。一家供水公司在一些管路中安装了1000一10000千瓦的小型涡轮发电机。目前,已建成5座渠道水力发电
In the Los Angeles area of the United States, there is little rain and water, and two water diversion channels are mainly used to solve the problem. One is from the Colorado River, and the other is from the north near Sacramento. The two channels converge in a large storage tank about 70 kilometers east of Los Angeles. The reservoir is high in elevation and is more than 400 meters above sea level. Due to the high water head, a pressure relief valve should be installed to protect the piping system from the tank to the local pipeline. A water supply company installed 1,000 to 10,000 kilowatts of small turbine generators in some pipelines. Currently, 5 channels of hydroelectric power have been built
