Needham Market STW: Wastewater Treatment in Mid Suffolk, Suffolk, England

Needham Market STW is a wastewater treatment plant located on Coddenham Road in Mid Suffolk, Suffolk, England. It serves a population of around 6,631 people, placing it in the small to medium agglomeration category under UK regulatory frameworks. The plant is situated inland, more than 50 km from the coast, and its treated effluent is discharged into local rivers that ultimately drain into the North Sea. As a plant serving fewer than 10,000 people, Needham Market STW is subject to the Urban Waste Water Treatment (England and Wales) Regulations 1994, which implement the EU Urban Waste Water Treatment Directive. These regulations require secondary treatment for discharges to freshwater and estuaries for agglomerations of this size. The receiving water body for the plant's discharge is part of the River Gipping catchment, which flows through Suffolk and joins the River Orwell at Ipswich before entering the North Sea. This watercourse supports diverse aquatic life and is important for local biodiversity. The plant's operation helps protect water quality in this sensitive riverine environment.

The plant discharges into the River Gipping catchment, which flows through Suffolk and joins the River Orwell at Ipswich, ultimately draining into the North Sea. This river system supports diverse aquatic life, including fish species such as brown trout and coarse fish, and provides habitat for waterfowl and other wildlife. The catchment is also used for recreation and agriculture, making water quality protection essential.
