The plant's designed capacity is 2,529 population equivalent, and it treats an average daily flow of 563 cubic meters. As a secondary treatment facility, it meets the standard required for inland freshwater discharges under UK regulations. The plant is operated as part of Southern Water's regional wastewater network, which manages treatment across Sussex and Kent. The treated effluent from ROBERTSBRIDGE STW is discharged into local watercourses that feed into the River Rother, a chalk stream that flows through East Sussex and into the English Channel at Rye Bay. The river supports diverse aquatic life, including brown trout and various macroinvertebrates, and is an important habitat for water voles and kingfishers. The plant's discharge is regulated to protect the ecological quality of the river and its downstream estuary.

The treated effluent from ROBERTSBRIDGE STW enters the River Rother, a lowland chalk stream that flows through the High Weald Area of Outstanding Natural Beauty. The river meanders southeastward past Bodiam Castle and joins the River Brede near Rye before discharging into the English Channel via Rye Bay. The Rother catchment supports a variety of aquatic species, including Atlantic salmon and sea trout, and its estuarine habitats are important for migratory birds. The plant's secondary treatment helps maintain water quality in this ecologically sensitive river system.
