Overview
Campo Maior Oeste is a secondary treatment plant serving 3,500 people in Campo Maior, Portugal. It discharges 583.56 m³/day of treated wastewater into the local environment.
Campo Maior Oeste is a municipal wastewater treatment plant located in Campo Maior, Portalegre, Portugal. It serves a population of approximately 3,500 residents, classifying it as a small agglomeration under EU standards. The plant is situated in the Alentejo region, near the border with Spain. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 4,000 m³/day and an average discharge volume of 583.56 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into a local watercourse that ultimately drains into the Guadiana River basin, which flows south to the Gulf of Cádiz in the Atlantic Ocean. The Guadiana River supports diverse aquatic ecosystems and is an important migratory corridor for fish species such as the European eel and the Iberian barbel.
Environmental context
The plant discharges into a tributary of the Guadiana River, one of the major rivers of the Iberian Peninsula. The Guadiana basin supports a variety of habitats, including Mediterranean forests and wetlands, and is home to several endemic fish species. Downstream, the river forms part of the border between Portugal and Spain before reaching the Atlantic Ocean. The region's semi-arid climate means that maintaining water quality in the Guadiana is critical for both ecological health and human uses such as agriculture and tourism.
