The Hyperion Treatment Plant is the largest and oldest wastewater treatment plant in Los Angeles. It can process as much as 850 million gallons of waste each day. When it was constructed in 1894, on the beaches of El Segundo, it simply discharged raw sewage directly into the sea—–today, thankfully, it performs full waste treatment.
The Cascades are a registered State Histor-ical Landmark. They are where the 338-mile Owens River Aqueduct terminates, bringing fresh water to L.A. The aqueduct’s construction, which finished in 1913, is a fascinating—–and murky—–tale of government corruption and outright theft. It was made famous by the film Chinatown. Owens Valley residents, watching their water disappear into pipes bound for Los Angeles, successfully sued the city. Some of their water began returning in late 2006.
