Stamullen Wastewater Upgrade Scheme

Wastewater Upgrade Scheme

Uisce Éireann is progressing works to upgrade the wastewater infrastructure in Stamullen, Co. Meath. 

Uisce Éireann, working in partnership with Meath County Council, is delivering the Stamullen Wastewater Upgrade Scheme. These improvement works will address the current limited capacity by converting the existing Stamullen Wastewater Treatment Plant to a pumping station, which will pump all wastewater to Balbriggan for treatment at the wastewater treatment plant there. The rising main has also been designed to cater for flows from Gormanston in future.

This project is split into two phases.

Approximately 2km of twin rising mains and a gravity sewer were completed on the R132 from the Delvin Bridge to Cardy Rock, Balbriggan, in 2022.

The remaining 4km of twin rising main have been completed and construction of pumping station is currently ongoing. David Walsh Civil Engineering Ltd is delivering these works on behalf of Uisce Éireann.

In Progress

What is involved as part of this project?

The scheme includes the following works:

  • Construction of a new pumping station at the existing Stamullen Wastewater Treatment Plant site.
  • Installation of approximately 6km of twin rising mains predominantly in public roads to connect to the Balbriggan sewer network at Cardy Rock for onward piping of the wastewater to Balbriggan Wastewater Treatment Plant.
  • Decommissioning of existing WwTP

What's happening next?

The 6km of twin rising mains being installed as part of this project has recently been completed. Construction of the pumping station and works to finalise the project are currently ongoing. This project is due for completion in Q3 2024. 
We will endeavour to keep you updated as this project progresses.

What are the benefits of this project?

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

  • Provide for the continued, planned development and growth of Stamullen and Gormanstown.
  • Provide a significant environmental benefit in that, the upgrade will help safeguard the river Delvin as there will no longer be discharge of treated wastewater to the river, which will facilitate an improvement in water quality.
