Planning application 2660877

A planning application has been lodged with Donegal County Council under reference 2660877. The applicant, UISCE ÉIREANN, is proposing a series of works at the Lough Mourne Water Treatment Plant in Meencrumlin, Lifford, Co Donegal. The application, received on 15 May 2026, is currently in the pre‑validation stage and a decision is expected by 9 July 2026.

The proposal covers the removal and decommissioning of existing Chemifloc tanks and soda ash silos, covering a footprint of more than 35 m². It also includes the replacement of a decommissioned Chemifloc tank that was installed in an open concrete bund with two new 25 000 L coagulating tanks. In addition, the applicant plans to construct a new chemical storage, preparation and dosing building for the water treatment plant. This building would house a 42 tne silo, a 2 000 L batching tank, a 10 000 L product tank, dosing cabinets and a new motor control centre with control panels for both dosing systems. The proposed building area is approximately 185 m².

Other elements of the application involve rerouting and reconfiguring filter wash water outlets and heavy sludge bleeds to direct the heavy sludge directly to the sludge plant. This change is intended to reduce the volumes of heavy sludge entering the sludge lagoons and lessen the need for sludge pumping. The plan also includes underground pipework and ducting, as well as all associated civil, landscaping and ancillary site development works.

The application is being considered by Donegal County Council, which will assess the proposal against local planning policies and environmental considerations. The council has not yet issued a decision, and the applicant remains in the pre‑validation phase.
