Seventy percent underground. That’s the Oceanside Water Pollution Control Plant for you. Imagine a hidden city beneath the earth. This isn’t just any wastewater treatment plant. It’s a marvel of engineering tucked away between Ocean Beach and Lake Merced.
The Oceanside Water Pollution Control Plant handles a significant portion of San Francisco’s wastewater. About 20% to be exact. That’s one-third of the city’s residents’ waste. The plant’s maximum capacity is a staggering 65 million gallons daily. On an average day though it processes a more modest 17 million gallons. Think about that volume next time you flush your toilet.
Construction on this impressive facility began in 1990. It cost a hefty $200 million. The project wrapped up in 1994. The design was brilliant. Most of the structure is hidden from view. Six feet of earth and landscaping camouflage the plant’s true size.
In 2008 a rather unusual proposal surfaced. A group wanted to rename the Oceanside Water Pollution Control Plant. They suggested the George W Bush Sewage Plant. Their goal was to spark conversation about the Iraq War. The proposal garnered significant media attention. Despite collecting enough signatures it failed at the polls. The majority of San Francisco voters rejected the name change.
This plant isn’t just about processing waste. It’s a testament to ingenuity and a quiet giant in San Francisco’s infrastructure. Its discharge point is 4.5 miles offshore. The treated water flows into the vast Pacific Ocean. The plant also underwent significant upgrades in recent years. Improvements to its digestion process aim for energy self-sufficiency. The Oceanside Water Pollution Control Plant is more than just pipes and pumps. It’s a piece of San Francisco’s hidden history. A vital part of the city’s unseen workings.
