Overview
REDONDELA wastewater treatment plant serves Moaña, Galicia, Spain, with a population of 22,795. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
REDONDELA is a wastewater treatment plant located in Moaña, within the province of Pontevedra, Galicia, Spain. The plant serves a population of approximately 22,795, classifying it as a medium-sized agglomeration under EU regulations. Its location near the coast of the Ría de Vigo places it in a sensitive estuarine environment. As a plant in the European Union, REDONDELA is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent between 10,000 and 150,000, the directive requires secondary treatment as a minimum. Given its proximity to a sensitive coastal area, more stringent treatment may be expected to protect the receiving waters. The plant's treated effluent is discharged into the Ría de Vigo, a coastal inlet of the Atlantic Ocean. This estuary supports diverse marine life, including shellfish beds and migratory fish species. Proper treatment is critical to prevent nutrient enrichment and maintain water quality in this ecologically productive area.
Environmental context
The REDONDELA plant discharges into the Ría de Vigo, a coastal inlet connected to the Atlantic Ocean. This estuary is part of the Galician Rías Baixas, known for their high biological productivity and shellfish aquaculture. The surrounding watershed includes the Lagares River and other small streams that drain into the ría. The area supports diverse aquatic life, including commercially important bivalves and migratory fish such as Atlantic salmon and sea trout. Nutrient loading from wastewater could lead to eutrophication, making effective treatment essential for preserving the ecological balance of this sensitive coastal ecosystem.
Frequently asked questions
The REDONDELA plant is located in Moaña, within the province of Pontevedra, Galicia, Spain. Its address is N-554, Cobres, Moaña, Vilaboa, Pontevedra, 36320.
The plant serves a population of approximately 22,795 people, classifying it as a medium-sized agglomeration under EU wastewater treatment regulations.
The treated effluent from REDONDELA is discharged into the Ría de Vigo, a coastal inlet of the Atlantic Ocean. This estuary is part of the Galician Rías Baixas, an ecologically productive area.
As a Spanish plant, REDONDELA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of 10,000 to 150,000 population equivalent, the directive requires secondary treatment, with more stringent measures in sensitive coastal areas.
In Spain, plants serving populations of this size are typically required to provide at least secondary treatment under the EU directive. Given the coastal location, advanced treatment may be necessary to protect the sensitive marine environment of the Ría de Vigo.
