rdf:langString The Oceanside Water Pollution Control Plant, also called the Oceanside Treatment Plant, is a wastewater treatment plant operated by the San Francisco Public Utilities Commission in San Francisco, California, United States. The award-winning facility is noted for its mostly underground construction inside a hollowed-out hill. It is between Ocean Beach and Lake Merced in the far-southwest corner of the city, near the San Francisco Zoo and the California National Guard. Oceanside is a secondary treatment plant handling about 20% of the city's wastewater from one-third of the city's residents. Its maximum capacity is 65 million US gallons (250,000 m3) per day, with an average daily dry weather flow of 17 million US gallons (64,000 m3). It discharges treated water about 4.5 miles (7.2 km) offshore into the Pacific Ocean. Construction on the US$200 million, 12-acre (49,000 m2) facility began in January 1990 and was completed in June 1994. 70% of the structure is underground, covered with 6 ft (1.8 m) of earth and landscaping.
