The Los Angeles County Department of Public Health (Public Health) has reopened the following swim areas that were closed due to sewage discharge from the City of Los Angeles Hyperion Water Reclamation Plant, after results from the ocean water samples collected over the last two days met State standards for acceptable water quality:

Beach # 110 – Dockweiler State Beach at Water Way Extension

Beach # 111 – Dockweiler State Beach at Hyperion Plant

Beach # 112 A – El Segundo Beach

Beach # 112 B – Grand Ave. Storm Drain

Following a sewage spill, Public Health collects water samples to determine bacteria levels. Public Health collected multiple ocean water samples for two consecutive days to determine if the water quality met State standards in the affected and nearby areas. In an abundance of caution, Public Health will continue to sample affected beaches through Thursday.

Hyperion Water Reclamation Plant discharged 17 million gallons of untreated sewage through their one and five-mile outlets which prompted the beach closures.

Public Health officials have notified lifeguards to remove beach closure signs after receiving the tests results confirming the beaches were safe to reopen. The Beach Water Quality webpage is updated to reflect the reopening.

Local nonprofit Heal the Bay said residents should still use caution when entering the water as there are four sites in the Santa Monica Bay that currently do exceed State standards and coming into contact with water at these locations could cause illness – it is unclear if these exceedances are due to the sewage spill, recent rainfall, or something else:

Topanga County Beach at the Topanga Canyon Lagoon
Will Rogers State Beach at the Santa Monica Canyon storm drain
Santa Monica State Beach at the Santa Monica Pier
Manhattan County Beach at the 28th Street storm drain
Recorded information on beach conditions is available 24-hours a day on the County’s beach advisory hotline: 1-800-525-5662. Information is also available online at
