LLANIDLOES STW is a wastewater treatment plant located in Llanidloes, Powys, Wales, United Kingdom. It serves a population of approximately 3,280 people, classifying it as a small agglomeration under UK and EU regulatory frameworks. The plant is situated inland, away from coastal areas, and treats wastewater from the local community. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 3,500 m³/day and an actual discharge volume of 730.24 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into a local watercourse, likely a tributary of the River Severn, as Llanidloes lies within the Severn catchment. The River Severn flows eastward through England into the Bristol Channel, supporting diverse aquatic life and providing water for agriculture and industry. The plant's secondary treatment helps protect downstream water quality and ecological health.
