UUisce Éireann has submitted a planning application to upgrade the Limerick (Bunlicky) Wastewater Treatment Plant and Regional Bioresource Centre, the utility’s largest wastewater investment in the Mid‑West.

The scheme is intended to meet rising demand from new homes and businesses while strengthening environmental protection.

The upgrade aims to ensure Limerick has the essential services needed to continue growing. It is expected to improve water quality in the Shannon Estuary, safeguard conservation habitats and better protect amenities used by communities, anglers, boat users and visitors.

The project is one of several nationally significant schemes advanced by Uisce Éireann that have been selected for accelerated delivery, with Government designation as critical infrastructure under the Critical Infrastructure Act 2026.

The planning application follows early engagement, including a non‑statutory public consultation and briefings with elected representatives and local stakeholders, with feedback used to refine the design now submitted for approval.

Minister for Housing, Local Government and Heritage, James Browne TD, said: "I am very happy to see this project taking the next step towards construction. The government has designated this project as critical infrastructure in recognition of the essential wastewater capacity it will provide to support growing communities, the vital housing delivery it will enable, and its associated environmental benefits. Its delivery will be critical to ensuring homes, businesses and communities have the wastewater services they need to thrive in the years ahead."
