Overview
ARDOCH STW serves Dumbarton, Scotland, treating wastewater for approximately 65,631 people. The plant operates under UK regulations and discharges into the local water environment.
ARDOCH STW is a wastewater treatment plant located in Dumbarton, West Dunbartonshire, Scotland, United Kingdom. It serves a population of approximately 65,631 people, placing it in the medium-to-large agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD), which has been retained in UK law post-Brexit. As a plant of this scale, it is expected to provide at least secondary treatment, with tertiary treatment required if discharging into sensitive areas. The plant's designed capacity is 1. 00 (likely in cubic meters per second or similar unit), and it is situated within 50 km of the coast, indicating potential influence on coastal water quality. The treated effluent from ARDOCH STW ultimately flows into the River Leven or directly into the Firth of Clyde, a major sea loch and estuary on Scotland's west coast. The Firth of Clyde supports diverse marine life, including commercial fisheries and important habitats for seabirds and seals. The plant's performance is critical to maintaining water quality in this ecologically sensitive area.
Environmental context
ARDOCH STW discharges into the Firth of Clyde via the River Leven or local watercourses. The Firth of Clyde is a large estuary that supports diverse aquatic life, including salmon, sea trout, and important bird populations. The area is ecologically sensitive due to its role as a migratory corridor and nursery ground for marine species. Maintaining high treatment standards is essential to protect these downstream ecosystems from nutrient pollution and other contaminants.
