Critical and complex repairs commenced Monday to a major trunk watermain that connects Ballymore Eustace Water Treatment Plant and the Saggart Reservoir, to safeguard water supply to 1.7 million customers in the Greater Dublin Area (GDA) including parts of Kildare. 

Specialist teams turned off the water late last night on the trunk main with repair and excavation crews now working day and night to repair the pipeline. 

Customers in Dublin and Wicklow may experience interruptions to their water supply including low pressure, discoloured water, or no water this Tuesday 13th and Wednesday 14th August 2024. 

Customers in Naas and surrounds will continue to have interrupted supplies and no water until later this evening at approximately midnight. Supply to essential services such as Naas hospital will be maintained.

Customers in Arthurstown, Tipperkevin, Rathmore and surrounding areas who have been impacted by a water outage from 8pm last night will continue to be without water until the early hours of the morning. 
Customers in the following areas may also be impacted from 7pm on 13 August until 4am on 14 August: Castlewarden, Sallins, Ardclough, Ballagh Cross, Baltracey Lane, Clane, Carbury, Rathcoffey, Hortland, Johnstown Bridge, Kill, Sherlockstown, Tirmoghan, Tuckmilltown and surrounding areas.

As the project progresses Uisce Éireann will work to minimise the impact to customers while carrying out the essential repair works. Customers can help to avoid water outages for themselves and others by using less water.

Stephen Burke, Regional Operations Manager for Uisce Éireann said the repair is highly complex due to the nature and size of the pipeline and the quantity of water it carries. 
“This pipeline is large and very challenging to work with. It was built in the 1980s, it’s buried deep underground - between 2 and 4 metres, and it’s 1.6 metres in diameter meaning the average adult could stand in it. "
“A large area around the leaking part of the pipe has been cleared so that we can access it to carry out the repair. The excavation alone is 14 metres wide and 5 metres deep. Works are progressing as planned at this point and we will keep the public up to date on any impacts to water services.” 

Uisce Éireann is again asking the public in Dublin, Kildare and Wicklow area to continue to make every effort to conserve water while the repair works are underway. 

The Uisce Éireann customer care helpline is also open 24/7 on 1800 278 278 and customers can also contact us on X @IWCare with any queries. For updates please visit the Water Supply Updates page or our dedicated project page Ballymore Eustace to Saggart Critical Pipeline Repair.

Customers in Kildare can access alternative water supplies at the following locations:
•    Rathmore Youth Hall 
•    Newtown Grove
•    Walshestown 
•    Aras Chill Dara 

Customers are reminded to use their own containers when taking water from the tanker and, as a precaution, boil the water before drinking.

Uisce Éireann is progressing a critical project to repair a major water main that connects the Ballymore Eustace Water Treatment Plant and the Saggart Reservoir and which supplies about one third of the drinking water for the Greater Dublin Area.

These essential works are necessary to repair a section of the pipeline that is likely to burst if not fixed. A burst on this pipeline would result in unplanned and widespread water outages that could take weeks to repair and affect up to 1.7 million people. 

To facilitate these critical works, customers in Naas, including Mullacash, Ballymore Eustace, Ardenode, Brannockstown, Carnalway, Killashee, Naas East, Naas West, Naas North, Caragh, Rathasker Heights, Bishopshill and surrounding areas will be impacted by a water outage from 9am to 6pm on Tuesday 13th August.

Ballymore Eustace is Ireland’s largest Water Treatment Plant and Saggart Reservoir is a newly upgraded reservoir to store drinking water. The Greater Dublin Area including many parts of Kildare are heavily dependent on this large pipeline which carries 220 million litres of water each day (80 Olympic swimming pools). It supplies about one third of the GDA’s drinking water. The pipe is over 25km long and is about the same height as an average adult. 

Speaking about the critical nature of the project for securing the Dublin area’s water supply, Mark O’Duffy, Uisce Éireann, commented: “Uisce Éireann has identified that this section of water main is at risk of bursting and causing major disruption for customers, unless repair works are carried out. This is a complex and challenging project due to the size, age and location of the pipe. Extensive planning and preparation has taken place in advance to enable us to carry out these works and minimise impact on water supplies."

Uisce Éireann acknowledges the inconvenience caused by interruptions to water supply and thanks the community in North Naas for their patience and cooperation while we deliver these essential works.”
As per best practice, most homes and businesses will have on-site water storage to provide a backup source of water for sanitation purposes. Uisce Éireann advises customers to familiarise themselves with their storage capacity. 

Following this type of work, occasionally issues such as cloudy water (air bubbles) or internal airlocks may arise. For advice on how to resolve these issues, please visit our outage advise page.
