All of the beaches in the Dun Laoghaire Rathdown area of Dublin have to close for a week due to a sewerage discharge.
Council officials say they've been made aware of a sewerage wastewater overflow at the treatment plant in Ringsend.
The overflow happened during heavy rainfall earlier this week.
Following advice from the HSE, temporary bathing prohibition notices have been issued from today for all public bathing sites in Dún Laoghaire-Rathdown.
That includes designated bathing areas such as Seapoint Beach, Sandycove Beach, the Forty Foot Bathing Area, Killiney Beach and White Rock Beach.
It's expected the ban will be in place for seven days.

This means that there is no swimming at all our beaches for the next 7 days. Read more: https://t.co/jefknjza4z pic.twitter.com/xziODa9kAR
