Moira Wastewater Treatment Plant, Moira, Northern Ireland | UK

Moira wastewater treatment plant is located on Bottier Road in Moira, County Down, Northern Ireland. The facility serves a population of around 5,085 people, classifying it as a small to medium agglomeration under EU regulations. The plant is part of the wastewater infrastructure managed within the Lisburn and Castlereagh District. As a plant operating in the United Kingdom, Moira WWTP is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment. The designed capacity is noted as 1.00, likely in cubic meters per day or similar units, indicating a modest scale. The treated effluent from Moira WWTP is discharged into local watercourses that ultimately drain into the Irish Sea via the Lagan River catchment. This coastal discharge contributes to the nutrient and water quality dynamics of the region, supporting aquatic life and recreational uses downstream. The plant plays a role in protecting the local watershed from untreated sewage and maintaining environmental standards.

Moira WWTP discharges into the Lagan River catchment, which flows into Belfast Lough and then the Irish Sea. The downstream environment includes estuarine and coastal habitats that support diverse aquatic species, including migratory fish. The plant's operations help mitigate nutrient loading and protect water quality in this ecologically sensitive coastal zone.
