EDAR LA FRANCA Wastewater Treatment Plant, Ribadedeva, Asturias, Spain

EDAR LA FRANCA is a wastewater treatment facility located in the parish of La Franca, within the municipality of Ribadedeva in the Asturias region of northern Spain. The plant serves a population of approximately 2,700 residents, reflecting its role in a small coastal community. Its location near the Cantabrian Sea places it within a sensitive coastal environment where treatment quality is critical. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,000 cubic meters per day and a reported discharge volume of 773.36 cubic meters per day, the facility operates well below its capacity, indicating room for future growth or seasonal demand. The advanced treatment level ensures high-quality effluent suitable for discharge into sensitive coastal waters. The treated effluent from EDAR LA FRANCA is discharged into the coastal waters of the Cantabrian Sea, part of the Bay of Biscay. This area supports diverse marine life and is important for local fisheries and tourism. The plant's advanced treatment helps protect the coastal ecosystem from nutrient pollution and pathogens, contributing to the ecological health of the region.

EDAR LA FRANCA discharges treated wastewater into the Cantabrian Sea, a coastal water body of the Bay of Biscay in the northeastern Atlantic Ocean. The local watershed includes small coastal streams that drain the Sierra de Cuera mountains. The coastal zone supports diverse marine habitats, including rocky shores and sandy beaches, and is important for migratory seabirds and local fish populations. Advanced treatment at the plant reduces nutrient loads and pathogens, helping to maintain water quality for recreational use and marine biodiversity.
