Overview
BAIONA wastewater treatment plant serves approximately 24,915 people in Baiona, Spain. Located near the coast, it operates under EU Urban Waste Water Treatment Directive standards.
The BAIONA wastewater treatment plant is a municipal facility serving the town of Baiona in the Galicia region of northwestern Spain. With a population equivalent of approximately 24,915, it is classified as a medium-sized agglomeration under EU regulations. The plant is situated near the Atlantic coast, reflecting the region's coastal character and the importance of protecting marine waters. As a Spanish facility, BAIONA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized to handle the local population's wastewater. Compliance with the directive ensures appropriate treatment before discharge. The plant's treated effluent ultimately reaches the Atlantic Ocean via local watercourses. The receiving environment includes the Rias Baixas, a series of coastal inlets known for their ecological richness and shellfish production. Protecting these waters is critical for maintaining biodiversity and supporting local fisheries and tourism. The plant plays a key role in safeguarding the marine ecosystem from nutrient pollution and pathogens.
Environmental context
The BAIONA plant discharges into the Atlantic Ocean via the Rias Baixas, a coastal ecosystem of high ecological value. These rias support diverse marine life, including commercially important shellfish beds and migratory bird populations. The plant's location within 50 km of the coast means its effluent can influence coastal water quality, making effective treatment essential for preserving the region's natural heritage and economic activities such as fishing and tourism.
