Linton-on-Ouse STW - Secondary Wastewater Treatment Plant, North Yorkshire

Linton-on-Ouse STW (Sewage Treatment Works) is a municipal wastewater facility located in the village of Linton-on-Ouse, North Yorkshire, England. The plant serves a population of approximately 2,330 residents, classifying it as a small agglomeration under UK and EU regulatory frameworks. It operates under the UK's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland discharges from agglomerations of this size. The plant provides secondary treatment, a biological process that removes organic matter and suspended solids. With a designed capacity of 2,369 m³/day and an average discharge volume of 518.74 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treatment process meets the regulatory standards for secondary treatment as defined by the Directive. The treated effluent is discharged into a local watercourse, likely a tributary of the River Ouse, which flows through the Vale of York before joining the Humber Estuary. The Humber Estuary is a major ecological feature supporting diverse bird life and fish species. The plant's discharge contributes to the overall water quality management in the Ouse catchment, which is important for downstream ecosystems and water resources.

The plant discharges into a local watercourse that feeds into the River Ouse, a major river in North Yorkshire. The River Ouse flows southeast through York and joins the River Trent to form the Humber Estuary, a large tidal estuary that empties into the North Sea. The Humber Estuary is ecologically significant, supporting migratory birds, fish, and intertidal habitats. The plant's secondary treatment helps protect water quality in this sensitive downstream environment by reducing organic pollution and nutrient loads.
