IPSWICH STW Wastewater Treatment Plant, Babergh, Suffolk

IPSWICH STW is a wastewater treatment plant located near the Orwell Bridge in Wherstead, Babergh, Suffolk, England. It serves a population of around 136,000, classifying it as a large agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated in a coastal region, within 50 km of the North Sea. As a large agglomeration, the plant is expected to provide secondary treatment as a minimum under the UWWTD, with potential for tertiary treatment if discharging into sensitive areas. The designed capacity is reported as 1.00 (likely in cubic meters per second or similar unit), indicating a substantial infrastructure. The plant operates under the regulatory framework of the UK Environment Agency, which enforces discharge permits under the Water Resources Act 1991. The treated effluent is discharged into the River Orwell estuary, a tidal river that flows into the North Sea near Felixstowe. The estuary supports diverse aquatic life and is an important migratory corridor for fish. The plant's location near the coast means its discharge can affect coastal water quality, necessitating stringent treatment standards.

The plant discharges into the River Orwell estuary, which flows into the North Sea. The estuary is a dynamic tidal environment supporting diverse aquatic life, including fish and bird species. The North Sea is a major marine ecosystem, and discharges from coastal plants must meet strict standards to protect water quality and marine habitats.
