Water supply issues in in Dun Laoghaire-Rathdown and North County Wicklow will improve over the coming days
Reservoir levels continue to stabilise and reach full capacity, with network flows and pressure returning to normal operating conditions
Uisce Éireann wishes to advise that some homes and businesses in Dun Laoghaire-Rathdown and North County Wicklow may experience some slight taste and odour issues with their water supply as the network returns to normal following a recent supply interruption at Vartry Water Treatment Plant.
Reservoir levels continue to stabilise and reach full capacity, with network flows and pressure returning to normal operating conditions. The taste and odour issues experienced by some customers are likely to have been caused by the emptying of some of the reservoirs and distribution supply pipes which could have disturbed internal deposits in concrete structures, pipes, and fittings. However the water fully meets regulatory parameters under the drinking water regulations and is safe to drink
Uisce Éireann, in partnership with Dun Laoghaire-Rathdown and Wicklow County Councils, continues to monitor the situation as water flows are expected to return to normal over the coming days as water flows to full capacity through the network.
Some homes and businesses in the following areas are likely to be temporarily affected; Newcastle, Newtownmountkennedy, Kilcoole, Kilpedder, Kilmacanogue, Fassaroe/Berryfield Lane, Kilcroney, Delgany, Killiskey, Nuns Cross, Coynes Cross, Prospect, Mount John, Timmore Lane, Dunran, Ballyvolan and Kiltimon, and North Bray.
Kevin Love, Regional Asset Operations Lead at Uisce Éireann said, "During this time, the volume of water in the reservoirs and pipes were relied upon to sustain water supply to the majority of customers. Uisce Éireann assures homes and businesses that only water that has been adequately treated and disinfected at Vartry Water Treatment Plant is permitted entry into reservoirs and pipe networks for onward supply to customers.
"We have carried out reactive investigative sampling and testing and confirm the water supplied to people's homes and businesses fully meets regulatory parameters under the drinking water regulations."
Kevin added: "Customers may experience some temporary discolouration of water and odour issues because of the works at Vartry Water Treatment Plant last week, which will continue to improve over the coming days. For advice on clearing discoloration and airlocks, visit our after an outage page."
