Overview
Castleblayney Waste Water Treatment Plant serves County Monaghan, Ireland, treating wastewater for approximately 13,700 people under the EU Urban Waste Water Treatment Directive.
Castleblayney Waste Water Treatment Plant is a municipal facility located on Black Island Walk in Castleblaney, County Monaghan, Ireland. It serves the local population of roughly 13,700 people, classifying it as a medium-sized agglomeration under EU regulations. As an Irish wastewater treatment plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to freshwater and estuaries for agglomerations of this size. The plant discharges treated effluent into the local water system, which ultimately drains into the Irish Sea via the River Fane and Dundalk Bay. This coastal discharge area supports diverse aquatic life and is an important ecological zone for migratory fish and bird species.
Environmental context
The plant's treated effluent flows into the River Fane, which runs through County Monaghan and Louth before entering Dundalk Bay, a coastal inlet of the Irish Sea. Dundalk Bay is a designated shellfish area and supports important fisheries and bird populations. The watershed is predominantly agricultural, with nutrient management being a key environmental concern to prevent eutrophication in the bay.
