Overview
Oldcastle Waste Water Treatment Plant serves County Meath, Ireland, treating wastewater for approximately 2,400 residents under EU Urban Waste Water Treatment Directive standards.
Oldcastle Waste Water Treatment Plant is a municipal facility located in County Meath, Ireland, serving the town of Oldcastle and surrounding areas. The plant treats wastewater from a population equivalent of approximately 2,400 people, operating under Ireland's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). As a small agglomeration under the EU UWWTD, the plant is required to provide appropriate treatment to protect local water quality. Irish wastewater treatment plants of this scale typically employ secondary treatment systems to meet regulatory standards for biological oxygen demand and suspended solids. The treated effluent is discharged into local watercourses that ultimately drain into the Irish Sea via the Boyne River catchment. The plant plays a key role in maintaining water quality in the region, supporting aquatic ecosystems and downstream environmental health.
Environmental context
The plant discharges into the Boyne River catchment, which flows eastward into the Irish Sea at Drogheda. This watershed supports diverse aquatic life, including salmonid populations, and is an important ecological corridor. The receiving waters are sensitive to nutrient enrichment, making effective wastewater treatment critical for maintaining water quality standards.
