BLACKFORD WWTW - Secondary Wastewater Treatment Plant in Blackford, Scotland

BLACKFORD WWTW is a wastewater treatment works located in Blackford, Perth and Kinross, Scotland. The plant serves a population of approximately 1,483 and operates under the regulatory framework of the Scottish Environment Protection Agency (SEPA). As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 2,419 cubic meters per day and currently treats an average daily flow of 330 cubic meters. Under the Urban Waste Water Treatment Directive (UWWTD), which is transposed into Scottish regulations, secondary treatment is the minimum standard for inland freshwater discharges from agglomerations of this size. The plant's capacity utilization indicates ample headroom for future growth or seasonal variations. The treated effluent is discharged to a local watercourse within the Allan Water catchment, which flows into the River Earn and eventually into the Firth of Tay, a major estuary on Scotland's east coast. The Firth of Tay supports diverse aquatic life, including salmon and migratory birds, and is an important ecological area. The plant's operation helps protect downstream water quality and the broader Tay estuary ecosystem.
