CWMGWRCH STW STW Wastewater Treatment Plant, Cwmgwrach, Wales

CWMGWRCH STW STW is a wastewater treatment plant located in Cwmgwrach, Neath Port Talbot, Wales, United Kingdom. The facility serves a population of approximately 5,366 people, placing it in the small-to-medium agglomeration category under UK and EU regulatory frameworks. The plant is situated near the A465 road in the Cynon Valley region. As a UK wastewater treatment plant, CWMGWRCH STW STW operates under the Water Industry Act 1991 and is subject to environmental permitting by Natural Resources Wales (NRW). For agglomerations of this size, secondary treatment is typically required under the Urban Waste Water Treatment Directive (91/271/EEC), which the UK transposed into national law. The plant's designed capacity is 1.00 (likely in megalitres per day or similar unit), indicating a modest scale. The plant discharges treated effluent into a local watercourse, likely a tributary of the River Neath or the River Dulais, which flows into the Neath Estuary and ultimately the Bristol Channel. This coastal discharge point is ecologically sensitive, supporting diverse aquatic life and migratory fish species. The plant's operation is crucial for protecting water quality in the downstream environment, including the Neath Estuary and the broader Severn Estuary ecosystem.

CWMGWRCH STW STW discharges into a local watercourse that drains into the River Neath, which flows into the Neath Estuary and then the Bristol Channel. The Bristol Channel is a major estuary with high tidal ranges and supports important habitats for birds, fish, and marine life. The plant's effluent quality is regulated to protect these downstream ecosystems, including designated sites of special scientific interest in the estuary.
