South Queensferry WWTW - Wastewater Treatment Plant in South Queensferry, Scotland

South Queensferry Wastewater Treatment Works (WWTW) is a municipal facility located in South Queensferry, a town in the Alba / Scotland region of the United Kingdom. The plant serves a population of approximately 8,590 residents, placing it in the small-to-medium agglomeration category under Scottish Water's management. It is situated near the Queensferry Crossing and Port Edgar Marina, close to the southern shore of the Firth of Forth. As a Scottish wastewater treatment plant, South Queensferry WWTW operates under the regulatory framework of the Urban Waste Water Treatment (Scotland) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 1.00 (likely in megalitres per day or similar unit), indicating a modest scale. The treated effluent from South Queensferry WWTW is discharged into the Firth of Forth, a major tidal estuary that flows into the North Sea. The Firth of Forth supports diverse marine life, including seals, seabirds, and commercially important fish species. The plant's location near the coast means its discharge contributes to the overall nutrient load in the estuary, which is monitored under Scotland's River Basin Management Plan to maintain good ecological status.

South Queensferry WWTW discharges into the Firth of Forth, a large estuary on Scotland's east coast that ultimately drains into the North Sea. The Firth of Forth is an ecologically important water body, supporting migratory fish such as salmon and sea trout, as well as wintering waterfowl populations. The estuary is subject to nutrient enrichment pressures from multiple sources, and the plant's discharge is regulated to protect the sensitive coastal and marine environment.
