The treated effluent from HEDON STW is discharged into the Humber Estuary, a major tidal estuary that flows into the North Sea. The Humber supports diverse aquatic life and is an important migratory corridor for fish species. The estuary's extensive mudflats and saltmarshes provide habitat for wading birds and waterfowl, making the area ecologically sensitive.

HEDON STW discharges into the Humber Estuary, which flows into the North Sea. The estuary is a large, dynamic system supporting diverse habitats including mudflats, saltmarshes, and reedbeds. It is an important site for migratory birds and fish, including species that rely on the estuary for spawning and nursery grounds. The plant's location near the coast means its discharge contributes to the overall nutrient and pollutant load entering the North Sea.
