KINGUSSIE WWTP: Secondary Wastewater Treatment in Kingussie, Scotland

KINGUSSIE WWTP is a municipal wastewater treatment facility located in Kingussie, Highland, Scotland. The plant serves a population of approximately 1,989 people, classifying it as a small agglomeration under Scottish water regulations. It is situated inland, more than 10 kilometers from the coast, and treats wastewater to secondary level. As a secondary treatment plant, KINGUSSIE WWTP employs biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 3,080 cubic meters per day and currently discharges an average of 442.82 cubic meters daily, indicating significant spare capacity. Under the Urban Waste Water Treatment (Scotland) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive, secondary treatment is the minimum standard for inland freshwater discharges from agglomerations of this size. The treated effluent from KINGUSSIE WWTP is discharged into a local watercourse, likely the River Spey or one of its tributaries, which flows through the Cairngorms National Park and ultimately into the Moray Firth. The River Spey is an ecologically important river known for its salmon fisheries and diverse aquatic habitats. The plant's operation helps protect the water quality of this sensitive river system.

KINGUSSIE WWTP discharges into the River Spey catchment, which flows north-east through the Cairngorms National Park and into the Moray Firth, an inlet of the North Sea. The River Spey is a designated Special Area of Conservation (SAC) for its Atlantic salmon, otter, and freshwater pearl mussel populations. The plant's secondary treatment ensures that effluent meets standards to protect these sensitive species and maintain the river's ecological status.
