Overview
BASUSTA wastewater treatment plant serves Zumaia, Euskadi, Spain, with a designed capacity of 1.00 and a population equivalent of 17,000. It operates under EU Urban Waste Water Treatment Directive 91/271/EEC.
BASUSTA is a wastewater treatment plant located in Zumaia, within the Basque Country (Euskadi), Spain. It serves a population equivalent of 17,000, classifying it as a medium agglomeration under EU regulations. The plant is situated near the coast, within 50 km of the shoreline, and its operations are subject to Spanish and European water quality standards. The plant is designed with a capacity of 1.00 (likely in thousands of cubic meters per day or similar units). Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size typically require secondary treatment, with tertiary treatment if discharging into sensitive areas. The plant's compliance with these standards ensures adequate protection of receiving waters. The treated effluent from BASUSTA likely discharges into local water bodies that drain into the Bay of Biscay, part of the Atlantic Ocean. The region's coastal and riverine ecosystems support diverse marine life and are important for local fisheries and tourism. Proper treatment helps maintain water quality and ecological balance in this sensitive coastal environment.
Environmental context
BASUSTA discharges into local streams or rivers that flow into the Bay of Biscay, a productive marine ecosystem supporting diverse fish, seabirds, and marine mammals. The Basque coastal area is ecologically sensitive, with habitats that rely on good water quality for spawning and migratory species. Effective wastewater treatment is crucial to prevent nutrient enrichment and protect downstream marine biodiversity.
