The Los Angeles Aqueduct Is Wild (practical.engineering)

Article summary

The Los Angeles Aqueduct is a 300-mile system that brings water from the Eastern Sierra to Los Angeles, enabled by a gravity-driven design that relies on a 2,500-foot elevation change. The aqueduct's construction was marked by controversy, including the displacement of Owens Valley residents and the destruction of the local ecosystem. The system has undergone changes and expansions over the years, including the addition of a second aqueduct and hydroelectric power plants. Today, the aqueduct remains a crucial part of Los Angeles' water supply, with about a third of the city's water coming from the Eastern Sierra.

What commenters say

• Desalination is a potentially viable alternative to traditional water sources, but it is energy-intensive and has significant environmental costs.
• The true cost of water is often hidden and externalized, and desalination may not be a cost-effective solution for urban areas.
• The Los Angeles Aqueduct is an engineering marvel that has enabled the growth of the city, but its construction and operation have had significant environmental and social impacts.
• The idea of using desalination to replace traditional water sources is not feasible due to the massive amount of energy required, which would be equivalent to a significant portion of the state's total solar power generation.
• The California aqueduct system is a complex and fragile network that relies on a combination of gravity, pumps, and hydroelectric power to deliver water to urban areas.
• The environmental impact of desalination, including the disposal of hyper-saline brine, is a significant concern that has not been fully addressed.
• The history of the Los Angeles Aqueduct is marked by controversy and shady dealings, including the displacement of Owens Valley residents and the destruction of the local ecosystem.
• The use of desalination as a solution to water scarcity is not a straightforward issue, and its implementation would require careful consideration of the energy and environmental costs.
