MUNGIA Wastewater Treatment Plant, Mungia, Euskadi, Spain

The MUNGIA wastewater treatment plant is located in Mungia, a town in the province of Bizkaia, within the autonomous community of Euskadi (Basque Country), Spain. The plant serves a population of approximately 19,312 people, classifying it as a medium-sized agglomeration under Spanish and EU regulations. As a plant in Spain, MUNGIA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The treated effluent from MUNGIA is discharged into local water bodies that ultimately drain into the Bay of Biscay, part of the Atlantic Ocean. The plant plays a key role in protecting the region's rivers and coastal waters from pollution, supporting aquatic life and recreational uses downstream.

The MUNGIA plant discharges into the local watershed that flows into the Bay of Biscay, a coastal area of the Atlantic Ocean. This region supports diverse marine life and is important for fisheries and tourism. The plant's operation helps maintain water quality in the downstream rivers and estuaries, which are ecologically sensitive and subject to EU water quality standards.
