ERSKINE STW - Clydebank, Scotland Wastewater Treatment Plant

ERSKINE STW is a wastewater treatment plant located in Clydebank, West Dunbartonshire, Scotland, United Kingdom. It serves a population of approximately 79,000 people, classifying it as a medium-to-large agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated near the River Clyde, a major watercourse in the region. As a plant serving over 10,000 population equivalent, ERSKINE STW is required to meet secondary treatment standards under the UWWTD. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant's designed capacity is reported as 1.00, though the unit is unspecified, indicating it likely operates within its intended scale. The treated effluent from ERSKINE STW discharges into the River Clyde, which flows through Glasgow and into the Firth of Clyde, an estuary leading to the North Atlantic Ocean. The River Clyde supports diverse aquatic life and is an important migratory corridor for Atlantic salmon and sea trout. The plant's operations contribute to protecting the water quality of the Clyde estuary and downstream marine environment.

ERSKINE STW discharges into the River Clyde, which flows through Glasgow and into the Firth of Clyde, a large estuary on Scotland's west coast. The Firth of Clyde supports diverse marine habitats, including seagrass beds and mudflats, and is an important area for seabirds and marine mammals. The plant's treatment helps maintain water quality in this ecologically sensitive estuary, which is subject to nutrient inputs from urban and agricultural runoff.
