Draperstown Wastewater Treatment Plant, County Londonderry, Northern Ireland

Draperstown wastewater treatment plant is located in the town of Draperstown, County Londonderry, Northern Ireland. It serves a population of around 3,275 people, making it a small municipal facility. The plant operates under the regulatory framework of the United Kingdom, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC) through domestic legislation. The plant provides secondary treatment, which is the standard required for freshwater discharges from agglomerations of this size under the Directive. The designed capacity of 3,296 cubic meters per day aligns with the population served, and the actual discharge volume of 729.13 cubic meters per day indicates operational headroom. The facility is owned and operated by the local water authority, consistent with Northern Ireland's centralized wastewater management. The treated effluent is discharged into local rivers that flow through the Moyola River catchment and eventually into Lough Neagh, the largest freshwater lake in the British Isles. Lough Neagh is an ecologically important site supporting diverse aquatic life and migratory birds. The plant's secondary treatment helps protect this downstream environment from nutrient pollution and organic loading.

The plant discharges into the Moyola River catchment, which flows into Lough Neagh, a large freshwater lake in Northern Ireland. Lough Neagh supports a rich ecosystem, including important fish populations and migratory waterfowl. The lake is sensitive to nutrient enrichment, so the plant's secondary treatment helps mitigate eutrophication risks. The downstream waters ultimately drain to the Atlantic Ocean via the River Bann.
