MONMOUTH STW STW - Wastewater Treatment Plant in Monmouth, Wales

MONMOUTH STW STW is a wastewater treatment plant located in Monmouth, Monmouthshire, Wales, serving a population of around 11,258. The plant is situated near the River Wye, which forms the border between England and Wales, and is part of the broader Wye catchment area. As a plant serving a medium-sized agglomeration, it is subject to the Urban Waste Water Treatment (England and Wales) Regulations 1994, which implement the EU Urban Waste Water Treatment Directive. These regulations require secondary treatment for discharges to freshwater and estuaries, with more stringent tertiary treatment if the receiving water is sensitive. The plant's designed capacity is 1.00 (likely in megalitres per day or similar unit), indicating a facility sized for its population. The treated effluent is discharged into the River Wye, which flows south to the Severn Estuary and then into the Bristol Channel. The River Wye is a Special Area of Conservation and supports diverse aquatic life, including salmon and otter populations. The plant's operation is critical to maintaining water quality in this ecologically important river system.

The plant discharges into the River Wye, a major river that flows through the Wye Valley Area of Outstanding Natural Beauty before joining the Severn Estuary. The Wye is a designated Special Area of Conservation, supporting species such as Atlantic salmon, sea lamprey, and otter. Downstream, the Severn Estuary is a large macrotidal estuary with important bird populations and migratory fish. The plant's treatment performance directly affects the ecological health of these water bodies.
