Planning permission secured to progress major wastewater upgrade in Limerick

31 January 2024

Communities across East Limerick are set to benefit from the welcome news that Uisce Éireann has secured planning permission for an extensive upgrade at Castletroy Wastewater Treatment Plant. 

Working in partnership with Limerick City and County Council, Uisce Éireann’s substantial upgrade will support existing and future population growth as well as improving and increasing the performance of the plant.

Castletroy Wastewater Treatment Plant has been serving the East Limerick suburbs of Castletroy, Annacotty, Mountshannon, Castleconnell as well as the University of Limerick and other local industry since the early 1990s.

The plant is currently operating at the upper limits of its capacity and Uisce Éireann has prioritised this upgrade, which will increase the plant’s current capacity by over 70% as well as providing stormwater storage for heavy rain events. 

Programme Manager with Uisce Éireann, Seamus Glynn, is looking forward to this vital project progressing. 

We are delighted to have secured planning for this very important project for businesses and communities in East Limerick. These works will ensure wastewater is treated appropriately now and into the future, supporting economic and population growth in these suburbs of Limerick. Among the host of benefits of this project is modernising and improving the performance of the existing plant, protecting the water quality in the Lower River Shannon and conservation habitats, protecting recreational waters for fishing and boating activities. Crucially, this upgrade will improve the health and integrity of the environment and ensure compliance with Irish and EU legislation now and into the future,” outlined Seamus.

A tender for the construction works will be issued to the market early this year. We will continue to work closely with the local community and will issue further updates as we progress with this significant project for communities and businesses in East Limerick.
