Bursledon STW (Sewage Treatment Works) - Eastleigh, Hampshire, England

Bursledon STW is a wastewater treatment plant serving the community of Bursledon and surrounding areas in Eastleigh, Hampshire, England. Located near the River Hamble estuary, the plant handles wastewater from a population equivalent of 7,270, placing it in the small to medium agglomeration category under UK regulations. As a plant in England, Bursledon STW operates under the Water Industry Act 1991 and is regulated by the Environment Agency. The plant's designed capacity is 1.00 (likely in megaliters per day or similar unit), indicating a modest scale. The treated effluent is discharged into the River Hamble, a tidal river that flows into Southampton Water, a major estuary on the south coast of England. Southampton Water then opens into the Solent, a strait separating the Isle of Wight from mainland England. The Hamble estuary supports diverse aquatic life, including important fish nurseries and bird populations, making the plant's discharge quality critical for local ecology.

Bursledon STW discharges into the River Hamble, a tidal estuary that flows into Southampton Water and then the Solent. The Hamble estuary is a designated Site of Special Scientific Interest (SSSI) for its intertidal mudflats, saltmarshes, and rich birdlife. The Solent is a key migratory corridor for seabirds and supports diverse marine habitats. The plant's location within 50 km of the coast means its discharge can influence coastal water quality, particularly in the sensitive estuarine environment.
