Santa Monica Bay Sewage Spill & Beach Closures



PUBLIC HEALTH ALERT: 17 million gallons of raw sewage were spilled into the Santa Monica Bay on July 11-12. Currently Dockweiler State Beach and El Segundo Beach are closed to the public. The City of Los Angeles and LA County Department of Public Health are testing beaches and water in the Santa Monica Bay.

This is a developing story from Heal The Bay and we will update information as new details come to light.

When did the spill occur? The sewage spill started at 7 pm on 7/11/2021 and stopped at about 5 am on 7/12/2021. We are told by City of LA’s Bureau of Sanitation that the spill was stopped early this morning at around 5 am and all sewage is now being treated normally.

How much was spilled? We understand 17 million gallons of raw sewage were spilled through the 1-mile outfall, which is directly offshore from the Hyperion Water Reclamation Plant in El Segundo.

Which beaches are impacted? Currently Dockweiler State Beach and El Segundo Beach are closed to the public. The City of Los Angeles and LA County Department of Public Health are testing beaches and water in the Santa Monica Bay.

What should the public do to protect themselves? We recommend the public stay out of the water until further notice. Also, check the Beach Report Card for the latest ocean water quality alerts in California, and review the River Report Card for water quality information about freshwater swimming holes in Los Angeles County.

What issues does this cause to people and to ocean wildlife? Bacteria and viruses in raw sewage are extremely dangerous to people and can carry a variety of diseases. Debris such as tampons and plastic trash, when released into the Bay, can harbor bacteria and can cause entanglement of wildlife, but it seems in this case those debris were successfully filtered out of the spill before it made it to the Bay.

Why did this happen? We understand the inflow to the Hyperion plant in El Segundo was severely clogged and flooded the facility. The sewage left the facility untreated through the 1-mile pipe and outfall.
