Ballincollig New Waste Water Treatment Plant, Cork, Ireland

Ballincollig New Waste Water Treatment Plant is a municipal facility serving the Ballincollig area of Cork, County Cork, in the Munster region of Ireland. The plant handles wastewater from a population of around 27,700, 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 agglomerations of this size discharging into freshwaters or estuaries. The plant's designed capacity is 1.00 (likely in cubic meters per second or similar unit), indicating its scale of operation. The treated effluent is discharged into the River Lee, which flows through Cork City and into Cork Harbour, a large natural harbor and estuary. Cork Harbour supports diverse aquatic life and is an important ecological area for fish, birds, and marine species. The plant plays a key role in protecting water quality in the Lee catchment and downstream coastal environment.

The plant discharges into the River Lee, which flows through Cork City and into Cork Harbour, a large estuary connected to the Celtic Sea. Cork Harbour is ecologically significant, supporting diverse fish populations, migratory birds, and marine habitats. The plant's operations help maintain water quality in this sensitive coastal environment, which is important for both biodiversity and local communities.
