NEILSTON STW - Wastewater Treatment Plant in Neilston, East Renfrewshire, Scotland

NEILSTON STW is a wastewater treatment plant located on Lochlibo Road in Neilston, East Renfrewshire, Scotland. Serving a population of around 5,900, it is classified as a small agglomeration under Scottish regulations. The plant is situated inland, approximately 50 km from the coast, and discharges into local watercourses that ultimately drain to the Firth of Clyde. As a Scottish wastewater facility, NEILSTON STW operates under the Urban Waste Water Treatment (Scotland) Regulations 1994, which transpose the EU Urban Waste Water Treatment Directive. For agglomerations of this size (under 10,000 population equivalent), secondary treatment is typically required unless the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in megalitres per day or similar units), indicating a modest scale. The treated effluent from NEILSTON STW is discharged into the local river system, which flows into the River Clyde via the Levern Water. The River Clyde is a major waterway in Scotland, supporting diverse aquatic life and flowing into the Firth of Clyde, an important estuary and sea loch. The plant plays a key role in protecting water quality in this catchment, particularly for downstream communities and ecosystems.

NEILSTON STW discharges into the Levern Water, a tributary of the River Clyde. The River Clyde flows through Glasgow and into the Firth of Clyde, a large sea inlet on Scotland's west coast. The Firth of Clyde supports important fisheries, including salmon and sea trout, and provides habitat for seabirds and marine mammals. The plant's location in a semi-rural area means its discharge must meet standards to protect these downstream ecosystems.
