TALGARTH STW BRONLLYS ROAD Wastewater Treatment Plant, Bronllys, Wales

TALGARTH STW BRONLLYS ROAD is a wastewater treatment plant located in Bronllys, a village in Powys, Wales, United Kingdom. The facility serves a population of approximately 2,911 people and is part of the region's municipal wastewater infrastructure. The plant is situated inland, away from coastal areas, and operates under the regulatory framework of the United Kingdom. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC), as retained in UK law. With a designed capacity of 3,081 m³/day and an average discharge volume of 648.09 m³/day, the facility operates well within its capacity. For agglomerations of this size (under 10,000 population equivalent), secondary treatment is the expected minimum standard. The treated effluent is discharged into a local watercourse, which ultimately drains into the River Wye catchment and then into the Severn Estuary. The plant plays a vital role in protecting the water quality of the River Wye, a Site of Special Scientific Interest (SSSI) and a Special Area of Conservation (SAC) known for its diverse aquatic life and migratory fish populations.

The plant discharges into a tributary of the River Wye, one of the most ecologically significant rivers in the UK. The Wye flows south through the Wye Valley, a landscape of deep gorges and ancient woodlands, before entering the Severn Estuary. The estuary supports important bird populations and is a major migratory route for salmon and sea trout. The plant's secondary treatment helps maintain water quality standards in this sensitive river system.
