SWANAGE STW - Swanage Wastewater Treatment Plant, Dorset, England

SWANAGE STW is a municipal wastewater treatment plant located on Peveril Point Road in Swanage, Dorset, England. It serves a population of around 22,017, classifying it as a medium-sized agglomeration under UK and EU regulatory frameworks. The plant is situated near the coast, within 50 km of the English Channel. As a UK wastewater facility, SWANAGE STW operates under the Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to coastal waters. The plant's designed capacity is 1.00 (likely in megaliters per day or equivalent), indicating it is sized to handle the local population's wastewater load. The plant is expected to meet regulatory standards for coastal discharge. The treated effluent from SWANAGE STW is discharged into the English Channel via a marine outfall, likely near Peveril Point. This coastal discharge must comply with stringent environmental standards to protect bathing waters and marine ecosystems. Swanage Bay is a popular tourist destination, and the plant plays a key role in maintaining water quality for recreational use and local biodiversity.

SWANAGE STW discharges into the English Channel, a major marine water body that connects to the Atlantic Ocean. The local watershed includes small coastal streams draining the Purbeck Hills. The discharge point near Peveril Point is in a designated bathing water area, requiring high treatment standards to protect public health and marine life. The area supports diverse coastal habitats, including rocky shores and seagrass beds, which are sensitive to nutrient pollution.
