Overview
BARREIROS wastewater treatment plant in Os Feás de Moreda, Galicia, Spain, serves a population of 1,806 with advanced treatment. The plant is closed but discharged 327.33 m³/day with a designed capacity of 4,000 m³/day.
BARREIROS is a former wastewater treatment plant located in Os Feás de Moreda, within the municipality of Barreiros in the province of Lugo, Galicia, Spain. It served a small population of 1,806 people, reflecting its role in a rural coastal community. The plant is now closed, but its infrastructure was designed to handle up to 4,000 m³/day, with an average discharge volume of 327.33 m³/day. The plant provided advanced treatment, which is a high level of purification beyond secondary treatment, typically involving nutrient removal or disinfection. In Spain, wastewater treatment is regulated under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment based on the sensitivity of receiving waters. For small agglomerations like this, advanced treatment may have been implemented to protect the nearby coastal environment. The plant is situated less than 10 km from the coast, indicating that treated effluent likely discharged into the Atlantic Ocean via local streams or directly. The coastal waters of Galicia are ecologically important, supporting diverse marine life and fisheries. Improving overall treatment efficiency and environmental protection.
Environmental context
The plant is located in the coastal region of A Mariña Oriental in Galicia, within 10 km of the Atlantic Ocean. The treated effluent likely discharged into the Cantabrian Sea, part of the Bay of Biscay, which supports rich marine biodiversity including commercial fish species and seabird colonies. The coastal waters are sensitive to nutrient inputs, and advanced treatment would have helped minimize eutrophication risks. The area is also known for its beaches and tourism, making water quality protection important for both ecology and local economy.
