Badwell Ash STW - Secondary Wastewater Treatment in Mid Suffolk, England

Badwell Ash Sewage Treatment Works (STW) is located in Mid Suffolk, Suffolk, England, serving a population of around 2,200. The plant provides secondary treatment, a standard level for small agglomerations in the United Kingdom. As a facility in England, it operates under the UK's implementation of the EU Urban Waste Water Treatment Directive (UWWTD), which requires secondary treatment for populations over 2,000. The plant's designed capacity of 2,199 population equivalent aligns with its current served population, indicating efficient operation. The treated effluent is discharged into local watercourses that feed into the River Waveney or River Gipping, ultimately reaching the North Sea. This discharge supports the ecological health of the region's rivers and estuaries, which are important habitats for aquatic life and migratory birds.

The plant discharges into local streams that drain into the River Waveney or River Gipping, both part of the Anglian River Basin District. These rivers flow into the North Sea via the Suffolk coast, an area of ecological importance for birdlife and marine biodiversity. The secondary treatment helps reduce nutrient loads, protecting downstream water quality in sensitive estuarine environments.
