PRESTEIGNE STW CLATTERBROOM STW - Presteigne Wastewater Treatment Plant, Wales

PRESTEIGNE STW CLATTERBROOM STW is a wastewater treatment plant located in Presteigne, Powys, Wales, United Kingdom. The facility serves a population of approximately 2,262 people, classifying it as a small agglomeration under UK and EU regulatory frameworks. The plant is situated inland, away from coastal areas, and treats wastewater from the local community. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 2,589 m³/day, with an actual discharge volume of 503.6 m³/day, indicating operational capacity well below design limits. As a UK facility, it operates under environmental permits issued by Natural Resources Wales (NRW), which set discharge consent conditions to protect receiving waters. The treated effluent is discharged to a local watercourse, likely a tributary of the River Lugg, which flows into the River Wye, a designated Site of Special Scientific Interest (SSSI) and a Special Area of Conservation (SAC). The River Wye is one of the most important rivers in the UK for its biodiversity, supporting salmon, otter, and freshwater pearl mussel populations. The plant's secondary treatment helps reduce organic pollution and protect this sensitive river ecosystem.

The plant discharges into a local watercourse that feeds into the River Lugg, a tributary of the River Wye. The River Wye is a major river in Wales and England, flowing into the Severn Estuary. The Wye catchment supports diverse aquatic life, including Atlantic salmon and European eel, and is recognized for its ecological importance. The plant's secondary treatment helps maintain water quality in this sensitive river system.
