Great Waldingfield STW - Secondary Wastewater Treatment in Babergh, Suffolk

Great Waldingfield STW is a wastewater treatment plant located in the village of Great Waldingfield, within the Babergh district of Suffolk, England. The plant serves a population of around 2,153 people and operates under the regulatory framework of the UK Environment Agency, which enforces the Urban Waste Water Treatment Directive (UWWTD) for agglomerations of this size. The plant provides secondary treatment, which is the standard required under the UWWTD for inland freshwater discharges from populations between 2,000 and 10,000. With a designed capacity of 2,175 m³/day and a current discharge volume of 479.33 m³/day, the plant operates well within its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the River Stour or its tributaries, which flow eastward to the North Sea. This discharge supports the ecological health of the river system, which is important for aquatic life and local biodiversity in the Suffolk countryside.

The plant discharges into the catchment of the River Stour, which flows through the Dedham Vale Area of Outstanding Natural Beauty before reaching the North Sea at Harwich. The river supports diverse aquatic habitats, including populations of brown trout and water voles. The secondary treatment provided helps maintain water quality standards in this ecologically sensitive region.
