Overview
SANT ANDREU DE LLAVANERES wastewater treatment plant serves Sant Vicenç de Montalt in Catalunya, Spain. It is located near the Mediterranean coast and serves a population of approximately 25,000.
SANT ANDREU DE LLAVANERES is a wastewater treatment plant located in Sant Vicenç de Montalt, within the Maresme region of Barcelona, Catalunya, Spain. The plant serves a population of around 25,000 people, placing it in the medium agglomeration category under European Union classifications. Its proximity to the Mediterranean coast means that treated effluent must meet stringent standards to protect coastal water quality. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. For plants discharging into sensitive coastal areas, additional nutrient removal may be mandated. The plant's discharge ultimately reaches the Mediterranean Sea via local streams or direct coastal outfall. The coastal waters of the Maresme region support diverse marine life and are important for tourism and recreation. Effective treatment is essential to prevent eutrophication and protect bathing water quality along this popular coastline.
Environmental context
The plant discharges into the Mediterranean Sea, a semi-enclosed sea with limited water exchange, making it sensitive to nutrient pollution. The coastal waters off Sant Vicenç de Montalt are part of the Catalan Sea, supporting seagrass meadows and fish nurseries. Proper treatment helps maintain water quality for tourism and marine biodiversity.
