The plant serves a population of around 2,901 and has a designed capacity of 3,500 m³/day, with an average discharge volume of 645.86 m³/day. As a secondary treatment facility, the plant provides biological treatment to remove organic matter and suspended solids. It operates under the UK's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant is regulated by the Environment Agency under the Water Resources Act 1991 and the Environmental Permitting Regulations. The treated effluent is discharged into local watercourses that drain into the River Great Ouse catchment, ultimately reaching The Wash on the North Sea coast. The plant plays a key role in protecting the local chalk streams and groundwater resources, which support diverse aquatic life and are ecologically sensitive.

The plant discharges into the River Great Ouse catchment, which flows through Buckinghamshire and Cambridgeshire before reaching The Wash, a large estuary and important habitat for migratory birds and marine species. The local watershed includes chalk streams that are sensitive to nutrient enrichment, making effective wastewater treatment critical for maintaining water quality and biodiversity.
