RAGLAN STW CHEPSTOW ROAD RAGLAN STW - Closed Wastewater Treatment Plant in Raglan, Wales

RAGLAN STW CHEPSTOW ROAD RAGLAN STW is a former wastewater treatment plant located on Station Road in Raglan, Monmouthshire, Wales. The plant served a population of approximately 1,210 people and was designed to handle a capacity of 1,300 cubic meters per day, with an average discharge volume of 269.39 cubic meters per day. It is now closed. As a secondary treatment facility, the plant provided biological treatment to remove organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), which the UK implemented, agglomerations of this size (1,210 population equivalent) are required to have secondary treatment. The plant's closure suggests that wastewater from Raglan is now conveyed to a larger regional facility. The plant's treated effluent was discharged into local watercourses that drain into the River Usk, a designated Special Area of Conservation (SAC) known for its salmon, lamprey, and otter populations. The River Usk flows south through Monmouthshire to the Severn Estuary, a major ecological and economic resource. The plant's operation contributed to protecting these sensitive waters from untreated sewage.

The plant discharged into tributaries of the River Usk, which flows through Monmouthshire to the Severn Estuary. The Usk is a high-quality river supporting Atlantic salmon, sea trout, and European eel. The Severn Estuary is a large, ecologically important water body with extensive mudflats and salt marshes that provide habitat for migratory birds. The plant's secondary treatment helped reduce nutrient and organic pollution, protecting downstream aquatic life.
