VALLVIDRERA is a wastewater treatment plant located in the Vallvidrera district of Barcelona, in the autonomous community of Catalonia, Spain. It serves a small population of 2,394 residents, reflecting its role in a suburban or peri-urban area within the greater Barcelona metropolitan region. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,500 cubic meters per day and an actual discharge volume of 912.53 cubic meters per day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent from VALLVIDRERA is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. As part of the Barcelona area's wastewater infrastructure, the plant helps protect the coastal environment and supports the ecological health of the region's water bodies, which are important for tourism and marine biodiversity.
Environmental context
The plant's discharge enters the local stream network that flows into the Llobregat River basin, which empties into the Mediterranean Sea near Barcelona. This coastal region supports diverse marine life and is a key area for tourism and recreation. Advanced treatment ensures that nutrient and pollutant loads are minimized, reducing the risk of eutrophication and protecting the sensitive coastal ecosystem.
