Overview
MAUCHLINE STW is an advanced wastewater treatment plant serving Mauchline, East Ayrshire, Scotland. It treats wastewater for approximately 4,389 people with a designed capacity of 6,000 m³/day.
MAUCHLINE STW is an advanced wastewater treatment plant located on Barskimming Road in Mauchline, East Ayrshire, Scotland. The facility serves a population of approximately 4,389 people and has a designed capacity of 6,000 m³/day, with an average discharge volume of 977.14 m³/day. As an advanced treatment plant, MAUCHLINE STW goes beyond the secondary treatment requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive typically requires secondary treatment, but the plant's advanced level indicates additional nutrient removal or polishing, likely due to the sensitivity of the receiving environment. The plant discharges treated effluent into the local watercourse, which ultimately drains into the River Ayr and then the Firth of Clyde. The Firth of Clyde is an important estuarine and coastal ecosystem supporting diverse marine life, including salmon and sea trout populations. The advanced treatment helps protect water quality in this ecologically significant area.
Environmental context
MAUCHLINE STW discharges into a tributary of the River Ayr, which flows westward into the Firth of Clyde. The Firth of Clyde is a large sea inlet on Scotland's west coast, supporting important fisheries and marine habitats. The advanced treatment level helps protect downstream water quality, particularly for salmonid spawning grounds and migratory fish corridors in the River Ayr catchment.
