Uisce Éireann marks the start of construction on a €20 million upgrade to Trim Water Treatment Plant

Uisce Éireann has marked the start of construction on a €20 million upgrade to Trim Water Treatment Plant in County Meath, Ireland.

The project, which will benefit over 12,000 customers, will address operational issues at the plant and water quality risks, as well as safeguarding water supply for homes and businesses in Trim who have frequently experienced disruption from outages.

A sod turning ceremony to mark the start of the works took place on Friday 20 June, 2025, led by Cathaoirleach of Meath County Council Wayne Harding; TDs, Senators and local councillors as well as officials from Uisce Éireann. 

The works will involve the construction of new treatment facilities, a control/administration building, internal re-purposing and reconfiguration of the existing water treatment building and all associated site works. Roof and ground-mounted solar panels will be installed in this project. Work is being carried out by Ward & Burke on behalf of Uisce Éireann.

Last week Uisce Éireann commenced two significant projects for the community of Maynooth in County Kildare, representing a €26 million investment in the town’s water and wastewater infrastructure. 

The Maynooth Transfer Pipeline and Maynooth Water Network Upgrade will provide the required capacity to support up to 13,000 additional housing units. Both projects are being delivered as part of Uisce Éireann’s Growth and Development Programme.

The Transfer Pipeline Project involves the construction of over 9km of new sewer pipeline between the existing Maynooth Wastewater Pump Station and Leixlip Wastewater Treatment Plant. 

The Water Network Upgrade Project involves the construction 1.2km of new water mains. The project will increase the supply capacity of the water network to service new developments in North Maynooth.

Both projects in Maynooth are being delivered on behalf of Uisce Éireann by Coffey Construction.
