MIODELO BERGONDO Wastewater Treatment Plant, Carrio, Galicia

MIODELO BERGONDO is an advanced wastewater treatment plant located in the parish of Miodelo, Bergondo, in the province of A Coruña, Galicia, Spain. The facility serves a population of approximately 4,665 and is situated near the Atlantic coast, reflecting the region's coastal geography. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 4,000 m³/day and an average discharge volume of 864 m³/day, the plant operates well within its capacity. As a Spanish facility, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on the sensitivity of receiving waters and population size. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Ría de Betanzos, a coastal inlet. This area supports diverse marine and estuarine ecosystems, and the advanced treatment helps protect water quality in this ecologically sensitive coastal environment.

The plant discharges into the Ría de Betanzos, a coastal inlet that connects to the Atlantic Ocean. This estuary supports a rich diversity of marine life, including fish, mollusks, and migratory birds. The advanced treatment level ensures that nutrient loads are minimized, helping to prevent eutrophication and maintain the ecological health of the ría and adjacent coastal waters.
