MUSKIZ Wastewater Treatment Plant, Muskiz, Spain

MUSKIZ is a wastewater treatment plant located in Muskiz, Bizkaia, in the autonomous community of Euskadi, Spain. It serves a population of approximately 12,000 residents, classifying it as a medium-sized agglomeration under EU classification. The plant is situated in the coastal municipality of Muskiz, near the Bay of Biscay. As a plant in Spain, MUSKIZ operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations of this size discharging into coastal waters. The directive also requires more stringent treatment if the receiving waters are designated as sensitive areas. The plant's designed capacity is 1.00 (likely in cubic meters per day or similar units), indicating its scale. The treated effluent from MUSKIZ is discharged into the local water system, which ultimately drains into the Bay of Biscay, part of the Atlantic Ocean. This coastal discharge requires compliance with EU standards to protect marine ecosystems. The plant plays a key role in safeguarding the coastal waters of the Basque Country, supporting both environmental health and local communities.

The MUSKIZ plant discharges into the local watershed that flows into the Bay of Biscay, a productive marine environment supporting diverse aquatic life. The coastal waters near Muskiz are part of the Cantabrian Sea, known for its rich biodiversity and important fisheries. The plant's operations help protect this marine ecosystem from nutrient pollution and pathogens, contributing to the ecological health of the region.
