Overview
CATOIRA wastewater treatment plant serves the town of Catoira in Galicia, Spain. It operates under the EU Urban Waste Water Treatment Directive, which sets treatment standards for agglomerations of this size.
The CATOIRA wastewater treatment plant is located in the municipality of Catoira, in the province of Pontevedra, Galicia, Spain. The plant serves a population of approximately 5,000 people, classifying it as a small agglomeration under EU regulations. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries from agglomerations of this scale. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Ulla River estuary (Ría de Arousa). This coastal area supports diverse marine life and is ecologically sensitive, making proper wastewater treatment essential for protecting water quality and aquatic habitats.
Environmental context
The CATOIRA plant discharges into the Ulla River basin, which flows into the Ría de Arousa, a coastal inlet of the Atlantic Ocean in Galicia. This estuary is a productive ecosystem supporting shellfish fisheries and migratory bird populations. The plant's location within 50 km of the coast means its effluent can influence coastal water quality, particularly in the sensitive ría environment.

The plant serves approximately 5,000 people, classifying it as a small agglomeration under EU wastewater treatment regulations.
The plant discharges into the Ulla River basin, which flows into the Ría de Arousa estuary and ultimately the Atlantic Ocean. Proper treatment helps protect these water bodies from pollution.
As a Spanish facility serving about 5,000 people, the CATOIRA plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries from agglomerations of this size.
For small agglomerations like CATOIRA, the EU directive mandates secondary treatment (biological treatment) to reduce organic matter and suspended solids. Spanish regulations also require compliance with effluent quality standards to protect sensitive coastal areas like the Ría de Arousa.
