Irish Water, in partnership with Dun Laoghaire Rathdown County Council, is replacing ageing water mains in Blackrock, Co Dublin to improve security of supply, improve water quality and reduce high levels of leakage.

The programme to replace the water mains in the Avoca Avenue area commenced on 7 September 2020. These works are being carried out as part of Irish Water’s national Leakage Reduction Programme.
