Irish Water, working in partnership with Louth County Council, is commencing a programme of watermains flushing to safeguard the water supply for customers in Dundalk and its environs. Following a large burst in Dundalk in June, manganese sediment became dislodged and carried through the network causing some customers to experience temporary discoloured water. These essential flushing works are required to clear any remaining manganese sediment from the distribution network and reduce the likelihood of future discolouration issues at the customer tap. These flushing activities are part of an overall action plan to address discolouration issues associated with high manganese levels found in the source water that feeds into Cavanhill water treatment plant. A programme of works at the Cavanhill water treatment plant has already been carried out including the installation of an interim Manganese treatment system to reduce manganese levels in the final treated water.
These essential maintenance works must be completed in phases. The first phase was completed Friday 3rd September. The second phase will commence today, Monday 6th September. While these essential works are ongoing, customers in the following locations will experience temporary discoloured water as sediment becomes dislodged and is removed by the flushing works between Monday 6 September and Friday 10 September; Bellews Bridge, Coxs Demense, Castletown Road, Boyle O’ Reilly Terrace, St Nicholas Avenue, Fatima, Barleyfield Armagh Road, Kilcurry, Balriggan, Carnbeg, St. Aphonsus Road, Barrack Street, Quay Street, Belfry Gardens, Seatown Place, Meadow Grove, Green Acres, Oaklawns, Avenue Road, Cluan Enda, Blakely Close, Ecco Road, Mount, Avenue, Ard Easmuin, Beechmount Drive, Green Gates, Lurgangreen, Dromiskin and Castlebelligham.
Customers will be given advance notice of when the next phase of flushing works will commence.
Any customers seeing discoloured water coming from their cold kitchen tap are advised to run the tap for a few minutes to restore the clear colour. If the colour does not restore to clear, customers are advised not the drink the water as a precaution, and should contact Irish Water using the contact details below.
It may take 2-3 hours for normal water supply to return to all customers when flushing is complete but it is important to continue to follow the HSE guidance on hand-washing.
Irish Water is encouraging customers to conserve water while these essential works are underway. There are ways to conserve water that will not impact on hygiene or handwashing. Simple water conservation efforts can have a big impact on reducing demand on the supply such as not running taps needlessly, taking showers instead of baths and to postpone using dishwashers and washing machines where possible. There are lots more tips on how to conserve water in your home on our website at https://www.water.ie/conservation/
Donal Heaney, Irish Water, said of the works, ”Irish Water and Louth County Council understands the inconvenience caused when flushing works occur and thanks customers for their patience while we complete these necessary works to remove any remaining sediment from the network and restore normal supply to impacted customers. Irish Water and Louth County Council regret any inconvenience caused.”
