Opened in 1963, the Point Loma Wastewater Treatment Plant treats approximately 175 million gallons of wastewater per day generated in a 450-square-mile area by more than 2.2 million residents.
Located on a 40-acre site on the bluffs of Point Loma, the Plant has a treatment capacity of 240 million gallons per day.
The plant is energy self sufficient through the harnessing of methane gas which power two caterpillar engines which in turn supply all the electricity to the plant.
is a notable facility due to its ability to treat 1 gallon of waste water for 1/3000th of a penny. That's 300,000 gallons for $1.00.
