Coffey Group have completed construction works on an €11.5 million project to upgrade the wastewater infrastructure in Enfield, County Meath, Uisce Éireann has announced.

The Wastewater Treatment Plant (WwTP) treats wastewater from Enfield and Johnstown Bridge in County Kildare and had been operating close to maximum capacity.

This project involved expanding and upgrading the plant to serve a population equivalent of 6,200 residents.

Two new settlement tanks and an outfall pipe were constructed and an innovative part of the project saw the installation of new reed beds which will receive, dewater and treat sludge from the plant.


Two transfer pipelines were installed beneath the River Blackwater to connect the existing wastewater treatment plant with the new infrastructure.

Flood defence works were also carried out to reduce the risk of flooding at the existing wastewater treatment plant site including bank repair works along a section of the River Blackwater. 

Outlining the benefits of this important project for the local community, Uisce Éireann Programme Manager, Conor Delaney, said: "We are delighted to have completed this vital upgrade to the wastewater infrastructure for the community in the Enfield and Johnstown Bridge areas. This project will benefit Counties Meath and Kildare for decades to come. 

"The modernisation and improvement of the wastewater infrastructure will accommodate further growth in the area and ensure that consistently high-quality treated wastewater is being discharged into the receiving waters. I want to take this opportunity to thank the community for their ongoing support and patience throughout the delivery of this vital project."

Enfield WwTP is now in operation and an extended testing period will run in the coming months to ensure satisfactory performance of the sludge drying reed beds through seasonal changes.
