Lampeter STW STW - Secondary Wastewater Treatment Plant in Lampeter, Wales

Lampeter STW STW is a municipal wastewater treatment facility located in Lampeter, Ceredigion, Wales, United Kingdom. The plant serves a population of approximately 3,165 residents, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). It is situated inland, more than 10 km from the coast. The plant provides secondary treatment, which is the standard required by the UWWTD for freshwater discharges from agglomerations of this size. The designed capacity is 8,678 cubic meters, with an actual discharge volume of 704.64 cubic meters per day, indicating significant spare capacity. As a UK facility, it operates under environmental permits issued by Natural Resources Wales (NRW), which enforce compliance with the UWWTD and the Water Framework Directive. The treated effluent is discharged into a local watercourse that ultimately drains into the River Teifi and then into Cardigan Bay (Irish Sea). The River Teifi is a designated Special Area of Conservation (SAC) for its Atlantic salmon, otter, and brook lamprey populations, making the plant's treatment performance critical for protecting downstream aquatic ecosystems.

The plant discharges into a tributary of the River Teifi, which flows through Ceredigion into Cardigan Bay, part of the Irish Sea. The Teifi catchment supports diverse aquatic life, including Atlantic salmon and European otter, and is designated as a Site of Special Scientific Interest (SSSI) for its riverine habitats. The inland location reduces direct marine impact, but the plant's secondary treatment helps maintain water quality in this ecologically sensitive river system.
