Llanybydder WWTW Ceredigion STW - Secondary Treatment Plant in Wales

Llanybydder WWTW (Wastewater Treatment Works) is located near the town of Llanybydder in Ceredigion, Wales, United Kingdom. The plant serves a population of approximately 1,991 people, classifying it as a small agglomeration under UK and EU wastewater regulations. It is situated inland, more than 10 km from the coast, and treats wastewater to secondary level. As a secondary treatment facility, Llanybydder WWTW employs biological processes to reduce organic matter and suspended solids, meeting the standards required by the Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater. The plant has a designed capacity of 1,991 population equivalent, with a reported discharge volume of 443.27 (likely in megalitres per year or similar unit), indicating operational capacity utilization. The treated effluent from Llanybydder WWTW is discharged into local watercourses that drain into the River Teifi, a major river in west Wales. The Teifi flows southwest through Carmarthenshire and into Cardigan Bay (Irish Sea). The river supports diverse aquatic life, including salmon and otter populations, and is an important ecological corridor in the region.

The plant discharges into the River Teifi catchment, which flows into Cardigan Bay, part of the Irish Sea. The Teifi is a designated Site of Special Scientific Interest (SSSI) for its salmonid fisheries and wetland habitats. The secondary treatment provided helps protect water quality in this sensitive river system, supporting biodiversity and recreational uses such as angling and canoeing.
