MINSTER STW is a wastewater treatment plant located in Minster, near Thanet in Kent, England. It serves a population of approximately 4,314, classifying it as a small agglomeration under UK and EU regulatory frameworks. The plant is situated close to the coast, within 10 km of the shoreline, and its operations are subject to the UK's environmental permitting regime. The plant provides secondary treatment, which is the standard required for discharges into coastal waters under the Urban Waste Water Treatment Directive (91/271/EEC). The designed capacity is 4,318 m³/day, and the average daily discharge volume is 960.45 m³, indicating a utilization rate well below capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that ultimately reach the North Sea. The plant plays a key role in protecting the coastal environment of the Thames Estuary and the North Sea, supporting water quality standards for bathing waters and marine ecosystems. Its location in a coastal area underscores the importance of effective treatment to prevent nutrient enrichment and safeguard marine life.

MINSTER STW discharges into local watercourses that drain into the Thames Estuary and the North Sea. The coastal waters in this region support diverse marine habitats, including important fish spawning grounds and migratory bird routes. Effective secondary treatment helps control nutrient inputs, reducing the risk of eutrophication in the sensitive estuarine and marine environment.
