Sewage Overflow causes Swimming Ban in Dun Laoghaire All beaches in Dun Laoghaire to Rathdown, Dublin has been issued week-long swimming bans by Dún Laoghaire-Rathdown County Council and Dublin City Council because of a wastewater overflow. The wastewater overflow came from the treatment plant in Ringsend. Irish Water said that the “storm water overflow” came from the plant for two hours over the course of Tuesday 4th & Wednesday 5th of June. Irish Water stated that the sewage overflow happened as “it should happen”.
Sean Laffey, the head of asset management at Irish Water said the overflow from the storm water tank was most likely very diluted. “During exceptional rainfall events the storm water tanks get full… we screen it for debris and then we discharge it back out into the environment”, said Mr Laffey. The Ringsend water treatment plant operated “as it was designed”.
Following the HSE’s advice, temporary bathing probations were issued in all public bathing areas from Dun Laoghaire to Rathdown. This includes bathing areas like Seapoint Beach, Sandycove Beach, the Forty Foot Bathing Area, Killiney Beach and White Rock Beach. The ban that has been issued is expected to last, for at least, for 7 days.
