Overview
Figueiros Alguber wastewater treatment plant serves the Cadaval area in Portugal. It has a designed capacity of 1.00 (unit unspecified) and serves a population of 8,200.
Figueiros Alguber is a wastewater treatment plant located in Cadaval, Lisbon District, Portugal. It serves a population of approximately 8,200 people, placing it in the small to medium agglomeration category under Portuguese and EU regulations. The plant is situated in the rural Lezíria region, near the village of Painho e Figueiros. As a Portuguese facility, Figueiros Alguber operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater. The regulatory framework ensures that the plant meets national standards for effluent quality. The plant's treated effluent is discharged into local watercourses that eventually drain into the Atlantic Ocean via the Tagus River basin or nearby coastal systems. The region's watershed supports agricultural activities and local ecosystems, making proper treatment essential for protecting downstream water quality and aquatic life.
Environmental context
The plant discharges into local streams that flow toward the Atlantic coast, likely contributing to the Tagus River basin or smaller coastal catchments. The downstream environment includes agricultural lands and sensitive estuarine habitats that support diverse aquatic species. Effective wastewater treatment is critical to prevent nutrient enrichment and maintain water quality in these ecologically important areas.
