Aberfeldy WWTP - Secondary Treatment Plant in Perth and Kinross, Scotland

Aberfeldy WWTP is a municipal wastewater treatment facility located in Aberfeldy, Perth and Kinross, Scotland. Serving a population of around 4,062, the plant provides secondary treatment to meet regulatory standards under the Urban Waste Water Treatment (Scotland) Regulations, which transpose the EU Urban Waste Water Treatment Directive. The plant has a designed capacity of 4,200 cubic meters per day and currently treats an average daily flow of approximately 904 cubic meters. As a secondary treatment facility, it employs biological processes to reduce organic matter and suspended solids before discharge. The plant operates within the framework of Scottish Water's management and is subject to monitoring by the Scottish Environment Protection Agency (SEPA). The treated effluent is discharged into a local watercourse that feeds into the River Tay, one of Scotland's major rivers. The River Tay flows through Perth and into the Firth of Tay, eventually reaching the North Sea. The plant's operations help protect the water quality of the Tay catchment, which supports diverse aquatic life and is important for fisheries and recreation.

The plant discharges into a tributary of the River Tay, which flows through the Tay Forest Park and into the Firth of Tay, a major estuary on Scotland's east coast. The Tay catchment supports Atlantic salmon, sea trout, and freshwater pearl mussels, making water quality management critical for these species. The plant's secondary treatment helps reduce nutrient loads and organic pollution, safeguarding the ecological health of the river and downstream marine environment.
