FASLANE STW - Secondary Wastewater Treatment Plant in Garelochhead, Scotland

FASLANE STW is a wastewater treatment plant located at HM Naval Base Clyde on the A814 road in Garelochhead, Argyll and Bute, Scotland. It serves a population of approximately 3,500 people, primarily from the naval base and surrounding community. The plant is situated on the Gare Loch, a sea loch opening into the Firth of Clyde. The plant provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into coastal waters. With a designed capacity of 3,500 cubic meters per day and an average discharge volume of 779.22 cubic meters per day, the plant operates well within its capacity. As a facility serving a small agglomeration (under 10,000 population equivalent), it meets the directive's requirements for appropriate treatment before discharge. The treated effluent is discharged into the Gare Loch, a sea inlet that flows into the Firth of Clyde and then the Irish Sea. The loch supports diverse marine life, including fish, crustaceans, and seabirds. The plant's coastal location means that proper treatment is essential to protect the sensitive marine environment of the Clyde estuary, which is an important area for fishing and recreation.

FASLANE STW discharges treated wastewater into the Gare Loch, a sea loch that connects to the Firth of Clyde and ultimately the Irish Sea. The Gare Loch supports a variety of marine species, including Atlantic salmon, herring, and seabirds. The plant's secondary treatment helps protect this coastal ecosystem from nutrient pollution and pathogens, maintaining water quality for local fisheries and recreational activities.
