Overview
Roscrea Waste Water Treatment Plant serves approximately 12,811 people in County Offaly, Ireland. The facility operates under Ireland's implementation of the EU Urban Waste Water Treatment Directive.
Roscrea Waste Water Treatment Plant is a municipal wastewater facility located in Mountheaton ED, Birr, County Offaly, Ireland. Serving a population of around 12,811, the plant is part of the country's wastewater infrastructure for the midland region. As an Irish wastewater treatment plant serving a medium-sized agglomeration, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for discharges to freshwater and estuaries for populations between 10,000 and 150,000, with more stringent tertiary treatment if discharging to sensitive areas. The plant's treated effluent is discharged into the local water environment, ultimately contributing to the River Shannon catchment, Ireland's longest river system. The Shannon flows through Lough Derg and into the Shannon Estuary, supporting diverse aquatic life and important habitats along its course.
Environmental context
The plant discharges into the River Shannon catchment, which drains through Lough Derg and the Shannon Estuary to the Atlantic Ocean. This watershed supports diverse aquatic ecosystems, including salmonid fisheries and wetland habitats. The Shannon is a vital ecological corridor for migratory fish and bird species, and water quality management is critical to maintaining its ecological health.
