Balbriggan Water Supply Network Upgrade

Uisce Éireann has completed essential works to upgrade the water mains in Balbriggan. These works have secured the water supply for local businesses and residents into the future.

Uisce Éireann, working in partnership with Fingal County Council, has completed upgrade works to the Balbriggan and Malahide Water Supply Schemes. Works in Howth are also nearing completion. This forms part of a €21.7 million investment in the Howth, Malahide and Balbriggan Water Supply Schemes. John Craddock Limited delivered these significant works on behalf of Uisce Éireann.

These works have increased the capacity of the water main system to meet current and future water supply demands in Howth, Malahide and Balbriggan by upgrading over 14km of water mains. The upgrade works carried out as part of this project will safeguard the water supply to this area, reduce interruptions to the drinking water supply and improve water pressure for homes and businesses.

What was involved?

Balbriggan Water Supply Scheme:

The Balbriggan Water Supply Scheme serves a population of approximately 24,200 and the reservoir at Kilsough is supplied by the Leixlip Water Treatment Plant. The existing water main between Jordanstown and Kilsough Reservoir was previously operating beyond its capacity, resulting in interruptions to supply and was inadequate to meet potential growth in the area.

This project included the:

• Construction of 5.7km of water mains from the Jordanstown Reservoir to the Kilsough Reservoir.
• An existing pumping station at Kilsough was also decommissioned

Malahide Water Supply Scheme:

The Malahide Water Supply Scheme serves a population of approximately 20,000 and is supplied by the Leixlip Water Treatment Plant. The existing water mains between Swords and the Seamount Reservoir in Malahide were operating beyond capacity, resulting in interruptions to supply. This project has upgraded the water mains to achieve adequate capacity to meet the Malahide Water Supply Scheme demands.

This project included the:

• Construction of approximately 2.5km of water mains between Swords and the existing Malahide Reservoir at Seamount.

Howth Water Supply Scheme:

The Howth Water Supply Scheme currently serves a population of approximately 20,900 and is supplied by the Leixlip Water Treatment Plant through the North Fringe Water Main. Previously, the existing water mains that supplied Howth’s main reservoir at Dungriffen from the North Fringe Water Main was operating beyond capacity. This resulted in interruptions to supply and was inadequate to meet potential growth.

This project included the:

• Construction of 6.1km of water mains, from the North Fringe Water Main to the existing reservoir at Dungriffen
• Rehabilitation and upgrade work at the existing Corr Bridge Pump Station
• Construction of a new pump station, including chlorine dosing facilities, at the Dungriffen Reservoir.

Works are nearing completion, with permanent reinstatement and commissioning works underway.

What are the benefits of these works?

The upgrade works carried out as part of this project have:

• Improve the security of the drinking water supply to householders and businesses in Malahide, Howth, Balbriggan and the surrounding areas
• Safeguard the water supply to this area
• Reduce interruptions to the drinking water supply
• Improve water pressure for homes and businesses.

Uisce Éireann would like to thank residents and businesses for their patience and cooperation during these significant works.
