BASSINGBOURN STW is a wastewater treatment works located in Bassingbourn, a village in the South Cambridgeshire district of Cambridgeshire, England. The plant serves a population of around 4,530 people, making it a small-scale facility within the region's wastewater infrastructure. It is situated inland, approximately 50 km from the coast, and its operations are regulated under the UK's environmental permitting framework. As a small agglomeration, the plant is expected to provide at least secondary treatment in line with the Urban Waste Water Treatment (England and Wales) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. The plant operates under a permit issued by the Environment Agency, ensuring compliance with discharge standards for the protection of receiving waters. The treated effluent from BASSINGBOURN STW is discharged into local watercourses that form part of the River Cam catchment. The Cam flows through Cambridgeshire and ultimately joins the River Great Ouse, which drains into the Wash, a large estuary and nature conservation area. The plant plays a role in maintaining water quality in this ecologically sensitive river system, which supports diverse aquatic life and is important for regional biodiversity.

The plant discharges into local streams within the River Cam catchment, which flows into the Great Ouse and then to the Wash, a major estuary on the North Sea coast. The Cam and Great Ouse support diverse fish populations and are important for migratory birds. The Wash is a key site for waders and wildfowl, making nutrient management critical to prevent eutrophication.
