OLDHURST STW - Wastewater Treatment Plant in Huntingdonshire, England

OLDHURST STW is a wastewater treatment plant located in Huntingdonshire, Cambridgeshire, England, United Kingdom. The facility serves a population of approximately 4,744 people, classifying it as a small agglomeration under the UK's implementation of the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas, and its operations are subject to environmental permitting by the Environment Agency. As a small agglomeration, the plant is expected to provide at least secondary treatment in accordance with the UWWTD, which is the standard for inland freshwater discharges. The UK's regulatory framework requires compliance with strict effluent quality standards to protect receiving water bodies. The plant's design and operation align with national guidelines for small-scale wastewater treatment. The treated effluent from OLDHURST STW is discharged into local watercourses that ultimately drain into the River Great Ouse and then into The Wash, a large estuary and bay on the North Sea. This catchment supports diverse aquatic life and is important for migratory birds. The plant plays a key role in maintaining water quality in this sensitive inland watershed.

OLDHURST STW discharges into local streams that feed the River Great Ouse, which flows into The Wash estuary on the North Sea. The Wash is a major ecological site supporting diverse bird populations and marine life. The plant's operations help protect this downstream environment from nutrient pollution and organic loading, which is critical for maintaining the ecological balance of the estuary and its surrounding wetlands.
