Forest Road Area, Swords – Works on 30” Watermain on Forest Road, Sword – Commencing 8th September
There is a leak on the 30″ watermain in the Forest Road area which is now scheduled to be repaired on 8th September. The area of the leak has been isolated and water is being backfed to the surrounding areas so there will be no loss of water to consumers. However, consumers may experience low water pressure from time to time over the coming days, particularly at peak times when there is a high demand on the water network. There may be some traffic disruption during the anticipated three day repair while machinery is accessing the site of repair or leaving it.
We apologise to for any inconvenience caused to consumers and or road users of the area while repairs are carried out.
