NEEDINGWORTH STW - Secondary Wastewater Treatment in Needingworth, Huntingdonshire

NEEDINGWORTH STW (Sewage Treatment Works) is located on Overcote Lane in the village of Needingworth, part of the Huntingdonshire district in Cambridgeshire, England. The plant serves a population of approximately 2,184 and operates under secondary treatment, which is the standard level required by the EU Urban Waste Water Treatment Directive for smaller agglomerations in non-sensitive areas. With a designed capacity of 2,700 cubic meters per day and an average discharge volume of 486 cubic meters per day, the plant operates well within its capacity. As a secondary treatment facility, it uses biological processes to reduce organic matter and suspended solids before discharging treated effluent. The plant is regulated under the UK's environmental permitting regime, which implements the EU directive requirements. The treated effluent from NEEDINGWORTH STW is discharged into local watercourses that drain into the River Great Ouse, a major river in eastern England. The Great Ouse flows through the Fens and ultimately into The Wash, an ecologically important estuary and wetland area. The plant plays a key role in protecting the water quality of this sensitive downstream environment.

NEEDINGWORTH STW discharges into local streams that feed the River Great Ouse, which flows through the Cambridgeshire Fens and into The Wash, a large estuary and designated Site of Special Scientific Interest. The Wash supports diverse bird populations and marine life, making nutrient management critical. Secondary treatment helps reduce organic pollution and protect the downstream aquatic ecosystem.
