Micklefield New STW Final Effluent - Leeds, England Wastewater Treatment Plant

Micklefield New STW Final Effluent is a wastewater treatment plant located in Micklefield, Leeds, West Yorkshire, England. It serves a population of approximately 2,048 people, classifying it as a small agglomeration under UK and EU regulatory frameworks. The plant is situated inland, away from coastal areas, and its treated effluent is discharged into local watercourses that ultimately drain into the Humber Estuary and the North Sea. 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. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 2,085 m³/day and currently discharges an average volume of 455.96 m³/day, indicating it operates well below its design capacity. The treated effluent from Micklefield New STW enters local streams and rivers that flow into the River Aire, a major watercourse in West Yorkshire. The River Aire eventually joins the River Ouse near Goole, contributing to the Humber Estuary, which is an ecologically important area supporting diverse aquatic life and migratory bird populations. The plant's operation helps protect these downstream environments from pollution.

The plant discharges into local watercourses that feed the River Aire, which flows through West Yorkshire before joining the River Ouse and ultimately the Humber Estuary. The Humber Estuary is a large, ecologically sensitive ecosystem that supports diverse fish, bird, and invertebrate communities. The plant's secondary treatment helps reduce organic pollution and protect water quality in this important downstream environment.
