The plant serves a population of approximately 2,577 people, classifying it as a small agglomeration under Irish and EU wastewater regulations. As a plant in Ireland, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater and estuaries for agglomerations of this size. The plant's treatment processes and capacity are managed to meet these standards, ensuring compliance with national and EU environmental objectives. The treated effluent is discharged into the local water environment, which ultimately drains into the River Boyne catchment and then into the Irish Sea. The plant plays a key role in protecting the water quality of local streams and rivers, supporting aquatic life and downstream ecosystems in County Cavan.

The plant discharges into the local water system, which flows into the River Boyne catchment and eventually reaches the Irish Sea. This watershed supports diverse aquatic habitats and is important for migratory fish species. The plant's operation helps maintain water quality in this sensitive freshwater environment, reducing nutrient and pollutant loads that could affect downstream ecology.
