Lower Liffey Valley Regional Sewerage Scheme - Leixlip Transfer Pipeline and Wastewater Network Upgrade

Uisce Éireann has completed works as part of €35 million investment to upgrade the wastewater network serving Leixlip and the surrounding areas.

The Greater Dublin Drainage Study (GDSDS) was completed in 2005 and comprised a strategic assessment of the existing wastewater network in Dublin (Fingal, South Dublin, Dublin City, and Dun Laoghaire-Rathdown), Meath, Kildare and Wicklow. This study identified strategic recommendations for wastewater infrastructure requirements. This project forms part of Uisce Éireann's investment plan to upgrade wastewater services in the area.

Uisce Éireann has identified that an upgrade to the existing wastewater network is required in the Greater Dublin Area to facilitate existing and future development in the area and to ensure a resilient wastewater network.

• Construction of approximately 4.85km sewer to the Leixlip Wastewater Treatment Plant
• Construction of a pumping station within the site boundary of the existing Leixlip Wastewater Treatment Plant
• Construction of approximately 8km of underground mains from the wastewater treatment plant to a sewer on the Damastown Road, near Blanchardstown, Co. Dublin
• The reinstatement of construction areas to match the original condition and associated site works

• Upgrade the wastewater network to facilitate existing and future development.
• Enable long term social and economic development.
• Ensure a resilient wastewater treatment network.
