KIRKBY MALZEARD STW - Secondary Wastewater Treatment Plant in North Yorkshire, England

KIRKBY MALZEARD STW is a wastewater treatment plant located in Grewelthorpe, near Kirkby Malzeard in North Yorkshire, England. It serves a population of around 2,100 people, classifying it as a small agglomeration under UK and EU regulatory frameworks. The plant is situated inland, away from coastal areas. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland discharges. The plant has a designed capacity of 2,251 cubic meters per day and currently discharges an average volume of 468 cubic meters per day, indicating operational headroom. As a UK facility, it operates under environmental permits issued by the Environment Agency, which set discharge consent conditions to protect receiving waters. The treated effluent is discharged into a local watercourse, likely a tributary of the River Ure, which flows through the Yorkshire Dales and eventually into the Humber Estuary and the North Sea. The plant plays a key role in protecting the water quality of the River Ure catchment, which supports diverse aquatic life and is used for recreation and agriculture.

The plant discharges into a local watercourse that feeds into the River Ure, a major river in North Yorkshire. The River Ure flows through the Yorkshire Dales and joins the River Ouse, which empties into the Humber Estuary, a large tidal estuary that supports important bird populations and fish species. The catchment is ecologically sensitive, with habitats for salmon, trout, and otters. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding downstream water quality.
