As climate change causes sea levels to rise, erosion is expected to worsen, further threatening coastal infrastructure like roads and sewers, and causing the beach to narrow. Ocean Beach is a challenging setting, with storm-driven waves contributing to erosion of coastal bluffs. This combined sewer and stormwater system has reduced the number of discharges into coastal waters by 90% and is a model of environmental performance. The Oceanside Treatment Plant and related facilities - completed in the early 1990s - were built to protect coastal water quality and bring San Francisco in compliance with the Clean Water Act.

On San Francisco's west side, gravity brings combined flows to the Westside Pump Station, where it is pumped to the Oceanside Treatment Plant. Learn more about San Francisco's combined sewer system. San Francisco has a combined wastewater and stormwater system, meaning that stormwater runoff is processed through the same system as wastewater from sinks and toilets. Ocean Beach is also home to major elements of San Francisco's wastewater and stormwater infrastructure. It draws a diverse population of more than 300,000 visitors each year and is an important piece of the Golden Gate National Recreation Area. Ocean Beach, a 3.5-mile stretch of sand along San Francisco's rugged Pacific coast, is one of the gems of the city's landscape.
