The plant is located within 10 km of the coast, discharging into the Solent and ultimately the English Channel. The New Forest area is ecologically sensitive, supporting diverse habitats including heathland, woodland, and coastal marshes. The treated effluent contributes to the nutrient balance of local watercourses that drain into the Solent, an area important for birdlife and marine biodiversity.

Brockenhurst STW discharges into local watercourses that flow into the Solent, a strait separating the Isle of Wight from mainland England, and eventually into the English Channel. The Solent is a biologically rich estuary supporting diverse marine life, including seagrass beds and important bird populations. The New Forest region is a designated area of outstanding natural beauty, and the plant's secondary treatment helps protect these sensitive coastal ecosystems from nutrient pollution.
