Growth and Development Programme - Maynooth Transfer Pipeline Project

Uisce Éireann is delivering a project to upgrade the wastewater network to enable growth and development in Maynooth and Kilcock.

The Maynooth Transfer Pipeline Project involves the construction of a pipeline between the existing Maynooth Wastewater Pump Station and Leixlip Wastewater Treatment Plant. Upgrade works are also required to the Maynooth Wastewater Pump Station. 

This project is being delivered to support existing and future developments within the community.  Construction of the new pipeline along with the required upgrade works to the Maynooth Wastewater Pump Station will improve the capacity of the existing wastewater network in the area, improving performance and reducing demands on the current network.

Delivered through Uisce Éireann's national Growth and Development Programme, the project represents a €24 million investment, and will provide the required wastewater network capacity to enable the development of an additional 11,500 housing units in Maynooth and Kilcock.

The works are being carried out on behalf of Uisce Éireann by Coffey Construction and are expected to be completed in 2027.

• Construction of 9 kilometres of new sewer pipeline from Maynooth Wastewater Pump Station at Dunboyne Road, to Confey in Leixlip.

• Upgrades to the existing Maynooth Wastewater Pump Station.

The benefits of these wastewater network works include: 

• Supporting social and economic development – This project will facilitate social and economic growth, including planned residential development.

• Improving the wastewater network – This project will upgrade the wastewater network, increasing the capacity to deliver reliable, sustainable high-quality wastewater services for the community.

Works commenced off-road in June 2025.

Site investigation commenced at the beginning of August along the proposed pipeline route on the L1014 and L1015 roadways.

A Stop/Go traffic management system is in operation to facilitate the works. These traffic controls are expected to remain in place until the end of the month.

Road Closure Application

Coffey Construction has applied to Kildare County Council to close the L1014, from its junction with the R157 to the L5050 junction at Catherinstown from Monday, 08 September 2025 to Sunday, 16 November 2025 to facilitate pipelaying works.

Alternative Routes: R157 bound stay on R157 for a further 1.1km until you come to the junction of L5050 Dunboyne Road. Turn right onto the L5050 to follow the diversion for 1km which will bring you to the end of the closure.

L1014 bound, closure starts at the junction of L5050 Dunboyne Road, diversion will begin with a right-hand turn. You will follow this diversion for 1km when you reach the junction of R157 / L5050. Turn left here onto the R157. Diversion will be in place for 1.1km until you reach the end of the closure.

We understand that this type of work can be inconvenient and works crews will make every effort to minimise any disruption these necessary works cause.

Diversionary routes will be clearly signposted, as agreed with the Council and An Garda Síochána. Emergency access and restricted local access will be maintained.
