OWLWOOD STW: Wastewater Treatment Plant in Leeds, England

OWLWOOD STW is a wastewater treatment plant located in Leeds, West Yorkshire, England. It serves a population of approximately 42,768 people, classifying it as a medium-sized agglomeration under UK and EU standards. The plant is situated inland, away from coastal waters, and its treated effluent is discharged into the local river system. As a UK wastewater facility, OWLWOOD STW operates under the Urban Waste Water Treatment Regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For a plant serving over 15,000 people, secondary treatment is required, and if the receiving water body is designated as sensitive, tertiary treatment may be mandated. The plant's treatment processes align with these regulatory expectations to protect water quality. The treated wastewater from OWLWOOD STW ultimately drains into the River Aire, which flows through West Yorkshire and joins the River Ouse near Goole. From there, the water enters the Humber Estuary and discharges into the North Sea. This river system supports diverse aquatic life and is important for regional ecology and water resources.

OWLWOOD STW discharges into the River Aire, a major watercourse in West Yorkshire that flows through urban and agricultural areas before joining the River Ouse. The combined waters enter the Humber Estuary, a large tidal estuary that supports important bird populations and fish species. The plant's operations help maintain water quality in this ecologically sensitive river system, which is used for recreation and supports downstream habitats.
