Overview
Celeiros wastewater treatment plant serves the Braga region in Portugal, treating wastewater for approximately 19,200 people. The facility operates under the EU Urban Waste Water Treatment Directive.
Celeiros wastewater treatment plant is located in the industrial park of Celeirós, within the municipality of Braga, Portugal. The facility serves a population of approximately 19,200 people, placing it in the medium agglomeration category under EU classification. As a Portuguese plant, Celeiros operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The treated effluent from Celeiros ultimately drains into the Cávado River basin, which flows through northern Portugal before reaching the Atlantic Ocean near Esposende. The Cávado River supports diverse aquatic life and is an important water resource for the region, including agricultural and industrial uses downstream.
Environmental context
The plant discharges into the Cávado River watershed, which flows westward through the Braga district and empties into the Atlantic Ocean. The river supports a variety of fish species and provides water for irrigation and industry. The downstream environment includes estuarine habitats near the coast that are ecologically sensitive and support migratory bird populations.
