CARRAS O CARBALLINO is a wastewater treatment plant located in O Carballiño, a municipality in the province of Ourense, Galicia, Spain. The plant serves a population of around 8,921 people, placing it in the small to medium agglomeration category under EU classification. 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. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas, which is common in parts of Galicia due to its numerous rivers and estuaries. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Miño River basin. This region is ecologically sensitive, supporting diverse aquatic life and important migratory fish species such as salmon and eels.
Environmental context
The plant discharges into the local river system within the Miño River basin, which flows into the Atlantic Ocean at the Ría de Vigo. This coastal area is ecologically important, supporting diverse marine and estuarine habitats. The region's high rainfall and rugged terrain make proper wastewater treatment essential to protect water quality and aquatic ecosystems.
