美国加利福尼亚州(以下简称加州)调水工程(SWP)将加州北部地区丰富的水资源调往干旱而人口密集的南部地区。工程于1957年开始兴建,1973年主体工程建成。1990年,达到设计输水能力,工程建设总投资50亿美元。SWP输水距离总长1318km(不包括用户自建的输水工程),其中人工渠道、隧洞与管道总长1040km;年均可供水量35.8～45.6亿m3;年均供水量为30～40亿m3;已建成各类水库19座,总库容83.33亿m3;已建泵站20座,总装机近2900MW,年均耗电量约100亿kW·h;已建水电站8座,总装机1190MW。
The California State of California Water Transfer Project (SWP) relocates the abundant water resources in Northern California to the dry and densely populated southern region. The project started construction in 1957, the main project was completed in 1973. In 1990, it reached the design capacity of water supply, with a total investment of 5 billion U.S. dollars. The total length of SWP water supply is 1318km (excluding the self-built water conveyance works), in which the total length of artificial channels, tunnels and pipelines is 1040km; the average annual water supply is 35.8-45.6 billion m3; the average annual water supply is 3-40 billion m3; 19 reservoirs have been built with a total storage capacity of 8.333 billion m3; 20 pumping stations have been built with a total installed capacity of nearly 2900MW and an average annual power consumption of about 10 billion kW · h; and 8 hydropower stations have been built with a total installed capacity of 1190MW.
