GALERA LA Wastewater Treatment Plant, la Galera, Catalunya, Spain

GALERA LA is a wastewater treatment plant located in la Galera, a municipality in the comarca of Montsià, Tarragona, Catalunya, Spain. The plant serves a population of approximately 1,548 people, placing it in the small agglomeration category under Spanish and EU regulations. The plant operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Its designed capacity is 1,200 m³/day, with a reported discharge volume of 300 m³/day, indicating operational headroom. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Mediterranean Sea via the Ebro River basin. The plant plays a key role in protecting the water quality of the region's streams and the downstream coastal environment.

The plant discharges into the Ebro River basin, which flows into the Mediterranean Sea. The downstream environment supports diverse aquatic life and is an important migratory corridor for fish species. The region's coastal waters are ecologically sensitive, and the plant's secondary treatment helps reduce nutrient and organic loading, mitigating eutrophication risks in the marine environment.
