HAY ON WYE SEWAGE TREATMENT WORKS STW - Cusop, England Wastewater Treatment Plant

HAY ON WYE SEWAGE TREATMENT WORKS STW is a wastewater treatment facility located in Cusop, Herefordshire, England. The plant serves a population of 2,100 and is situated near the River Wye, a major watercourse in the region. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants before discharge. The plant operates under the UK's implementation of the EU Urban Waste Water Treatment Directive (UWWTD), which requires secondary treatment for agglomerations of this size. The designed capacity is 2,752 m³/day, with an average daily discharge volume of 467.53 m³/day, indicating operational headroom. The regulatory framework ensures compliance with environmental standards for effluent quality. The treated effluent is discharged into the River Wye catchment, which flows into the Severn Estuary and ultimately the Bristol Channel. The River Wye is a Site of Special Scientific Interest (SSSI) and supports diverse aquatic life, including salmon and otter populations. The plant's operation is critical to maintaining water quality in this ecologically sensitive river system.

The plant discharges into the River Wye catchment, a major tributary of the Severn Estuary. The River Wye supports a rich ecosystem, including Atlantic salmon, sea trout, and otter populations. Downstream, the Severn Estuary is a large tidal basin with important bird habitats and migratory fish routes. The plant's secondary treatment helps protect these sensitive environments from nutrient pollution and organic loading.
