The €5 million investment by Uisce Éireann to upgrade the wastewater network in Cookstown, Tallaght is progressing well and is on target to be completed this summer.

This vital project will provide the required wastewater capacity to support the future potential development of up to 1,600 new homes in the locality. 

Works underway involve the installation of over 650m of new sewer pipeline on the Belgard and Airton Roads.

This project is being delivered to support existing and future developments within the community. It will improve the capacity of the existing wastewater network in the area, while improving performance and reducing demands on the current network.  

Uisce Éireann’s Padraic Fitzgerald said, “This significant investment will not only address current capacity constraints but will also facilitate planned residential development, helping to unlock housing and economic potential in the area. Residents and businesses will benefit from a higher performing wastewater network, which will support sustainable growth and development and enable the community to thrive.   

“We understand that this type of work can be inconvenient to commuters and works crews are making every effort to minimise disruption in the area. We would like to thank the community for their patience and co-operation while these citical works progress.”  

GMC Utilities Group Ltd are delivering these works on behalf of Uisce Éireann, with completion of works expected in summer 2026.

To safely and efficiently deliver these complex works, localised traffic management is in place.  To minimise disruption in the area, the next section of works at the Belgard Road/Airton road junction will be completed between Thursday evenings and Monday mornings inclusive.

Uisce Éireann's Growth and Development Programme is a national programme of targeted investment to increase the capacity of water and wastewater infrastructure to enable social and economic growth and development, including the delivery of essential housing.
