Spean Bridge/Roybridge WwTW - Secondary Wastewater Treatment in Spean Bridge, Scotland

Spean Bridge/Roybridge WwTW is a wastewater treatment works located on Insh Road in Spean Bridge, Highland, Scotland. The plant serves a population of approximately 1,015 people and is part of the region's municipal wastewater infrastructure, managed under Scottish Water's operational network. The facility provides secondary treatment, which is the standard level required under the Urban Waste Water Treatment (Scotland) Regulations for discharges into freshwater. The plant has a designed capacity of 2,510 cubic meters per day and currently treats an average daily flow of about 226 cubic meters. This indicates the plant operates well within its design capacity, allowing for future growth or seasonal variations. The treated effluent from Spean Bridge/Roybridge WwTW is discharged into a local watercourse that ultimately feeds into the River Spean and then into Loch Linnhe, a sea loch on Scotland's west coast. This discharge contributes to the overall water quality of the Spean catchment, which supports salmonid fisheries and diverse aquatic life. The plant plays a key role in protecting the sensitive freshwater and marine environments downstream.

The plant discharges into a tributary of the River Spean, which flows into Loch Linnhe, a sea loch on the west coast of Scotland. The Spean catchment is ecologically important, supporting Atlantic salmon and other native fish species. The loch and its surrounding waters are part of a dynamic coastal ecosystem that includes seal colonies and seabird populations. Maintaining high treatment standards helps protect these habitats from nutrient enrichment and pollution.
