Overview
Barrantes Ribadumia wastewater treatment plant serves 16,681 people in Ribadumia, Galicia, Spain. Located within 50 km of the coast, it operates under EU Urban Waste Water Treatment Directive standards.
Barrantes Ribadumia is a wastewater treatment plant located in the parish of Barrantes, within the municipality of Ribadumia, in the province of Pontevedra, Galicia, Spain. The plant serves a population of approximately 16,681 people, classifying it as a medium agglomeration under EU regulations. Its location in the O Salnés region places it in a coastal area with significant agricultural and tourism activity. As a Spanish facility serving a population between 10,000 and 100,000, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. The designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a moderate scale. It is expected to meet the directive's standards for biological treatment and nutrient removal where necessary. The plant discharges into the local hydrological network, which ultimately drains into the Ría de Arousa, a coastal inlet of the Atlantic Ocean. This estuary is ecologically important, supporting diverse marine life and shellfish fisheries. The plant's proximity to the coast (within 50 km) means its effluent quality is critical to protecting the sensitive coastal ecosystem and maintaining water quality for tourism and aquaculture.
Environmental context
The Barrantes Ribadumia plant is situated in the O Salnés region, part of the Umia River basin, which flows into the Ría de Arousa on the Atlantic coast. The Ría de Arousa is a productive estuary known for its shellfish beds and marine biodiversity. The plant's treated effluent contributes to the freshwater inflow into this coastal system, where nutrient management is essential to prevent eutrophication and protect the ecological balance of the ría. The area supports important fisheries and tourism, making water quality a priority.
Frequently asked questions
The plant is located in the parish of Barrantes, within the municipality of Ribadumia, in the province of Pontevedra, Galicia, Spain. Its address is Os Conchidos, Ribadumia, Barrantes.
The plant serves a population of approximately 16,681 people, classifying it as a medium-sized agglomeration under EU regulations.
The plant discharges treated effluent into the local hydrological network, which ultimately flows into the Ría de Arousa, a coastal estuary of the Atlantic Ocean.
As a Spanish facility serving over 10,000 people, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment and, in sensitive areas, tertiary treatment for nutrient removal.
Plants of this scale in Spain typically employ secondary biological treatment, such as activated sludge or trickling filters, to meet EU standards. In coastal areas like Galicia, additional nutrient removal may be required to protect sensitive estuarine environments.
