FOCHABERS WWTP - Secondary Treatment Plant in Upper Dallachy, Scotland

FOCHABERS WWTP is a municipal wastewater treatment facility located near Upper Dallachy in Moray, Scotland. The plant serves a population of approximately 3,068 people, classifying it as a small agglomeration under Scottish water regulations. It operates under the regulatory framework of the Scottish Environment Protection Agency (SEPA), which enforces discharge standards aligned with the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, a standard requirement for inland freshwater discharges in Scotland. With a designed capacity of 3,500 m³/day and an actual discharge volume of 683.04 m³/day, the plant operates well within its capacity. The treatment process ensures that effluent meets quality standards before release into the receiving environment. The treated effluent from FOCHABERS WWTP is discharged into a local watercourse that flows into the River Spey or its tributaries, eventually reaching the Moray Firth and the North Sea. The River Spey is a nationally important salmon river, and the Moray Firth supports diverse marine life, including dolphins and seabirds. The plant's secondary treatment helps protect these downstream ecosystems from nutrient pollution and pathogens.

The plant discharges into a local watercourse within the Spey catchment, which drains into the Moray Firth, a coastal inlet of the North Sea. The River Spey is one of Scotland's fastest-flowing rivers and supports Atlantic salmon, sea trout, and otter populations. The Moray Firth is a key habitat for bottlenose dolphins and migratory birds. Secondary treatment reduces biochemical oxygen demand and suspended solids, safeguarding these ecologically sensitive waters from eutrophication and contamination.
