KIMBOLTON STW - Secondary Wastewater Treatment in Huntingdonshire, England

KIMBOLTON STW is a wastewater treatment plant located in Great Staughton, near Huntingdonshire in Cambridgeshire, England. It serves a population of around 3,710 people, classifying it as a small agglomeration under UK and EU regulatory frameworks. The plant is situated inland, away from coastal areas, and its operations are part of the region's municipal wastewater infrastructure. The plant provides secondary treatment, which is the standard level 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's designed capacity of 3,710 population equivalent aligns with the population served, indicating appropriate sizing. Treated effluent from KIMBOLTON STW is discharged into local watercourses that drain into the River Great Ouse catchment, ultimately reaching The Wash estuary and the North Sea. The plant plays a role in protecting the ecological health of these waters, supporting aquatic life and recreational uses downstream.

The plant discharges into the River Great Ouse catchment, which flows through Cambridgeshire into The Wash, a large estuary and important ecological area. The Wash supports diverse bird populations and marine life, making nutrient management critical. The plant's secondary treatment helps reduce organic pollution, contributing to the health of this downstream environment.
