THE Water Corporation is warning people not to swim or beach fish between Bent Street Jetty and View Road on Safety Bay Road as a wastewater overflow has occurred in the area.
Wastewater overflowed upstream of the Charthouse Road Wastewater Pump Station to a drain, which discharges at the corner of Malibu Road and Safety Bay Road.
Early estimates indicated about 3.4 million litres (equivalent to about 1.5 Olympic swimming pools) of wastewater had overflowed from the drain to the beach and ocean.
Warning signs have been erected on the beach 500 metres north and south of where the overflow occurred.
Tidal currents, wave motion and ocean swells will ensure that the wastewater disperses quickly.
Water Corporation was notified of the issue by the City of Rockingham yesterday afternoon and crews responded immediately.
The cause of the overflow is still being investigated.
The Water Corporation issued an apology for any inconvenience the overflow may cause.
A statement yesterday said the Water Corporation would advise when the water was safe for swimming and beach fishing is again permitted.
