The plant's designed capacity is 1.00 (likely in megalitres per day or similar), indicating a facility sized for its catchment. The treated effluent from ST OSYTH STW is discharged into local watercourses that flow into the North Sea. The receiving environment includes coastal waters that support diverse marine life and are important for recreation and tourism. The plant plays a key role in maintaining water quality in the Essex coastline, which is part of the Greater Thames Estuary ecosystem. Proper treatment helps prevent eutrophication and protects habitats such as salt marshes and mudflats that are vital for migratory birds.

The plant discharges treated effluent into local watercourses that drain into the North Sea via the Essex coastline. This area is part of the Greater Thames Estuary, a dynamic ecosystem supporting diverse aquatic life, including fish, invertebrates, and migratory birds. The coastal waters are used for recreation and shellfisheries, making effective wastewater treatment essential to prevent nutrient enrichment and bacterial contamination. The plant's location near the coast means its discharge can directly affect marine water quality, particularly in sensitive intertidal habitats.
