YSTRADGYNLAIS WWTW OFF WIND ROAD STW - Ystalyfera Wastewater Treatment Plant

YSTRADGYNLAIS WWTW OFF WIND ROAD STW is a wastewater treatment plant located in Ystalyfera, Neath Port Talbot, Wales, United Kingdom. It serves a population of approximately 11,515 people, classifying it as a medium-sized agglomeration under UK water industry standards. The plant is situated inland, more than 50 km from the coast, and its operations are integral to the local sanitation infrastructure. As a UK wastewater treatment facility, the plant is regulated under the Water Industry Act 1991 and the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. For a population of this scale, secondary treatment is typically required, with tertiary treatment expected if the receiving water is in a sensitive area. The plant's designed capacity is 1.00 (likely in megaliters per day or similar units), indicating a moderate treatment capacity. The plant discharges treated effluent into a local watercourse, likely a tributary of the River Tawe, which flows south into the Bristol Channel. This water body supports diverse aquatic life and is used for recreation and fisheries. The plant's operation helps protect water quality in the Tawe catchment and downstream coastal environment.

The plant discharges into a local river, likely part of the River Tawe catchment, which flows into the Bristol Channel. The Tawe supports salmon and sea trout populations and is designated as a Site of Special Scientific Interest (SSSI) in parts. Downstream, the Bristol Channel is a major estuary with important bird habitats and marine ecosystems. Effective treatment at this plant helps maintain water quality standards for these sensitive environments.
