Another swimming ban has been introduced on some beaches in South Dublin.
Dun Laoghaire-Rathdown County Council said heavy rain over the past 48 hours caused a wastewater overflow at several treatment facilities in the area.
It said that as a precaution, swimming has been banned at Seapoint, Sandycove and Forty Foot beaches.
It brings the total number of beach closures in Dublin to four, after the announcement by Dublin City Council that Dollymount was also shut to swimmers for the same reason.
It comes after a week-long swimming ban was issued for eight beaches in the Dublin area earlier this month due to an overflow of sewage at the treatment plant in Ringsend.
The Councils said the latest bans will remain in place until water conditions return to normal and test-results are clear.
