A century later, it continues to be a marvel in modern engineering. The LA Aqueduct brought water from the Owens Valley hundreds of miles away to a growing area in need of additional resources to sustain its people and their endeavors, helping spur an economy that today rivals that of many nations.
Due to its weight, the transportation of water is very energy intensive. Unless it has the assistance of gravity, a canal or long-distance pipeline will need pumping stations at regular intervals.In this regard, the lower friction levels of the canal make it a more economical solution than the pipeline.ajor water transportation projects [edit]. The Grand Canal of China, finished in the 7th Century AD and measuring 1,794 kilometres (1,115 mi). The California Aqueduct, near Sacramento, is 715 km (444 mi) long.
