Allanfearn WWTP Inverness - Wastewater Treatment in the Scottish Highlands

Allanfearn WWTP is a wastewater treatment facility located at Alturlie Point near Inverness, in the Highland region of Scotland. It serves a population of around 80,000, making it a medium-to-large agglomeration under Scottish Water's management. The plant is situated on the coast of the Moray Firth, an inlet of the North Sea. As a Scottish plant, Allanfearn WWTP operates under the Urban Waste Water Treatment (Scotland) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. For agglomerations of this size, secondary treatment is required, with tertiary treatment expected if discharging into sensitive areas. The plant's designed capacity is 1. The plant's treated effluent is discharged into the Moray Firth, a large coastal embayment that supports diverse marine life, including bottlenose dolphins and seabird colonies. The firth is an important area for fisheries and conservation, with the Inner Moray Firth designated as a Special Area of Conservation. The plant's coastal location means its discharge must meet strict environmental standards to protect the sensitive marine ecosystem.

Allanfearn WWTP discharges into the Moray Firth, which connects to the North Sea. The firth is a productive marine environment supporting bottlenose dolphins, seals, and numerous seabird species. The Inner Moray Firth is recognized for its ecological importance, hosting diverse habitats including mudflats and saltmarshes. The plant's coastal discharge requires careful management to prevent nutrient enrichment and protect the area's biodiversity.
