Limerick City Waste Water Treatment Plant: Serving Limerick, Ireland

Limerick City Waste Water Treatment Plant is a major municipal facility serving the city of Limerick in County Limerick, Ireland. Located in the Munster region, the plant treats wastewater from a population of approximately 280,000, making it a large agglomeration under EU classification. As a large-scale treatment plant in Ireland, the facility is expected to comply with the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for all agglomerations over 2,000 population equivalent and tertiary treatment in sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating substantial infrastructure to handle the city's wastewater load. The plant discharges treated effluent into the River Shannon, Ireland's longest river, which flows through Limerick and into the Shannon Estuary before reaching the Atlantic Ocean. The Shannon Estuary is a vital ecological corridor supporting diverse aquatic life, including salmon and sea trout, and is an important migratory route for birds. The plant's operations are critical to maintaining water quality in this sensitive downstream environment.

The plant discharges into the River Shannon, which flows through Limerick and into the Shannon Estuary, a large coastal inlet that connects to the Atlantic Ocean. The estuary supports diverse aquatic habitats, including important fish spawning and nursery grounds. Maintaining high treatment standards is essential to protect these downstream ecosystems from nutrient pollution and other contaminants.
