HALESWORTH STW - Wastewater Treatment Plant in East Suffolk, England

HALESWORTH STW is a municipal wastewater treatment plant located on Blyth Road in Halesworth, East Suffolk, Suffolk, England. The facility serves a population of approximately 7,630 people, placing it in the small-to-medium agglomeration category under UK and EU regulatory frameworks. As a plant serving fewer than 10,000 people, HALESWORTH STW operates under the UK's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of the receiving environment. The treated effluent from HALESWORTH STW ultimately drains into the North Sea via local watercourses. The plant plays a key role in protecting the water quality of the Blyth River and the surrounding Suffolk coastal environment, which supports diverse aquatic life and is an important area for migratory birds.

HALESWORTH STW discharges into the River Blyth, which flows eastward through the Suffolk countryside before entering the North Sea at Southwold. The river and its estuary support a variety of fish species, including brown trout, and provide habitat for waterfowl and wading birds. The coastal waters of the North Sea in this region are ecologically sensitive, with important nursery grounds for marine fish and areas of conservation interest. The plant's treatment performance is critical to maintaining water quality in this catchment.
