It serves a population of around 4,593 people, making it a small-scale facility within the UK's wastewater infrastructure. The plant is situated near the village of Alconbury and Little Stukeley, in the Cambridgeshire and Peterborough region. As a small agglomeration, Alconbury STW is subject to the UK's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland discharges from populations over 2,000.

The treated effluent from Alconbury STW is discharged into local watercourses that drain into the River Great Ouse catchment. The Great Ouse flows through East Anglia and into the Wash, an ecologically important estuary and bay. The plant plays a key role in protecting the water quality of these downstream environments, supporting aquatic life and recreational uses.

Alconbury STW discharges into the River Great Ouse catchment, which drains into the Wash, a large estuary on the east coast of England. The Wash supports diverse bird populations and is a vital habitat for migratory waterfowl. The plant's treatment helps maintain water quality in this sensitive ecosystem, reducing nutrient loads that could otherwise contribute to eutrophication in the estuary.
