AIREDALE STW - Secondary Wastewater Treatment Plant in Fairburn, England

AIREDALE STW is a wastewater treatment plant located in Fairburn, North Yorkshire, England, United Kingdom. It serves a population of approximately 4,241 people, classifying it as a small agglomeration under UK and EU regulatory frameworks. The plant is situated inland, away from coastal areas, and operates within the broader context of England's water management infrastructure. The plant provides secondary treatment, which is the standard required under 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 4,343 m³/day and currently discharges 944.19 m³/day of treated effluent, indicating operational headroom. The treated effluent from AIREDALE STW is discharged into a local watercourse, which ultimately drains into the Humber Estuary via the River Ouse and the Humber River system. This catchment supports diverse aquatic life and is an important ecological corridor in northern England. The plant's operation helps protect downstream water quality in the Humber Estuary, a major inlet of the North Sea.

AIREDALE STW discharges into a local watercourse that flows into the River Aire, a tributary of the River Ouse. The River Ouse then joins the River Trent to form the Humber Estuary, which drains into the North Sea. The Humber Estuary is a large, ecologically significant ecosystem that supports migratory fish, wading birds, and diverse aquatic habitats. The plant's secondary treatment helps reduce nutrient and organic pollution, contributing to the health of this downstream environment.
