AMMANFORD STW Wastewater Treatment Plant, Swansea, Wales

AMMANFORD STW is a wastewater treatment plant located in Mawr, near Swansea, in the Cymru / Wales region of the United Kingdom. It serves a population of around 30,470, classifying it as a medium-sized agglomeration under European Union regulations. The plant is situated inland, more than 50 kilometers from the coast. As a facility serving over 10,000 people, AMMANFORD STW is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum standard. The designed capacity of the plant is 1.00 (likely in megaliters per day or similar unit), indicating its scale. The regulatory framework ensures compliance with discharge standards. The treated effluent from AMMANFORD STW is discharged into local watercourses that ultimately drain into the Bristol Channel, a major estuary on the southwest coast of the UK. The receiving waters support diverse aquatic life and are important for regional biodiversity. The plant's operation helps protect downstream ecosystems from nutrient pollution and other contaminants.

AMMANFORD STW discharges into the River Loughor catchment, which flows into the Loughor Estuary and then into the Bristol Channel. The Bristol Channel is a large, ecologically productive estuary that supports important bird populations, fish species, and marine habitats. The plant's treatment processes help maintain water quality in this sensitive coastal environment, reducing the risk of eutrophication and protecting aquatic life.
