€9 million investment to replace the nearly 50 year old water main prone to frequent bursts

Irish Water is progressing the €9 million Swords water main replacement project.  To date 3.2 kms of the water main has been replaced from Forrest Road to the intersection at the Lord Mayors Pub on Main Street. Forest Road will fully reopen to the public on Sunday, 24 June. 

Traffic notification

The next phase of the works construction work will take place from Monday, 25 June on Main Street from the junction of Forrest Road to the Malahide Road junction (Swords Garda Station). To facilitate this section of works there will be no left turn on to Main Street from Forest Road. A one-way system will be in place from the Lord Mayors to Swords Garda station. North Bound traffic on Main Street will be required to follow the diversion. Southbound traffic on Main Street will not be affected. 

A letter drop to residents and businesses was carried out in advance of these works. Advanced warning digital signs are in place to notify the public of the upcoming works. These works have been scheduled for to coincide with school holidays in order to avoid traffic congestion and minimise the impact on residents, businesses and road users. 

Where are the works taking place?

The 30 inch concrete water main was laid in 1970. Since the project commenced the water main has been replaced between Cooks Road and Forest Road south of Swords, along Forest Road to the junction with Main Street. The works will now progress along Main Street and North Street and onwards to Lissenhall, ending near the Swords north M1 motorway junction. 

Once replaced, the new water main will greatly improve the reliability of the water supply for homes and businesses in Swords and also to customers in Malahide and Portmarnock served by the by the Malahide Reservoir. Throughout the project, residents and businesses are being kept informed of all works in advance. 

Commenting on the project Paul Hickey, Regional Lead, said “The Swords water main replacement project is progressing well and to date 3.2km of the 5.2km water main has been replaced. The next phase of the works are taking place along Main Street from the Lord Mayors pub to the  Garda Station at the Malahide Road junction and are scheduled to take three weeks to complete. We thank the residents, businesses and road users for their understanding while we carry out this critical work.  A one- way traffic management system will be in place for this phase of the works and we will continue to keep the community updated at each stage of the project”.
