CANAMERO Wastewater Treatment Plant, Cañamero, Extremadura, Spain

CANAMERO is a wastewater treatment plant located in Cañamero, a municipality in the province of Cáceres, Extremadura, Spain. The plant serves a population of approximately 3,500 people, classifying it as a small agglomeration under Spanish and EU regulations. It is situated inland, away from coastal areas, and treats wastewater from the local community. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 3,400 m³ per day, and the current discharge volume is 634.37 m³ per day, indicating operational capacity well within design limits. The plant is part of Spain's municipal wastewater infrastructure, regulated under national transposition of EU directives. The treated effluent is discharged into a local watercourse, likely a tributary of the Tagus River basin, which flows westward through Spain and Portugal to the Atlantic Ocean. The plant plays a key role in protecting local water quality and supporting the ecological health of the surrounding rural environment in Extremadura.

The plant discharges into a local stream that feeds into the Tagus River basin, one of the Iberian Peninsula's major river systems. The Tagus flows through central Spain and Portugal, eventually reaching the Atlantic Ocean near Lisbon. The downstream environment includes agricultural areas and natural habitats that depend on good water quality. The plant's secondary treatment helps reduce organic pollutants and nutrients, supporting the ecological balance of the receiving waters.
