POBRA DE TRIVES Wastewater Treatment Plant, A Pobra de Trives, Galicia, Spain

POBRA DE TRIVES is a wastewater treatment plant located in A Pobra de Trives, a municipality in the province of Ourense, Galicia, Spain. The plant serves a population of approximately 3,137 residents, classifying it as a small agglomeration under Spanish and EU regulations. It is situated inland, away from coastal areas, and treats wastewater from the local community. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 2,500 m³/day and an actual discharge volume of 556.23 m³/day, the facility operates well below its capacity, indicating room for future growth. As a Spanish plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size, but the plant exceeds this requirement with advanced treatment. The treated effluent is discharged into a local watercourse, likely a tributary of the Sil River, which flows into the Miño River and eventually reaches the Atlantic Ocean. The plant plays a key role in protecting the local watershed and downstream ecosystems from pollution, supporting water quality in the region.

The plant discharges into a local stream that feeds into the Sil River, a major tributary of the Miño River. The Miño River flows through Galicia and forms part of the border with Portugal before emptying into the Atlantic Ocean. This watershed supports diverse aquatic life and is important for regional biodiversity. The advanced treatment helps minimize nutrient and pollutant loads, protecting downstream water quality and ecological health.
