NAVACONCEJO Wastewater Treatment Plant, Navaconcejo, Extremadura, Spain

NAVACONCEJO is a wastewater treatment plant located in the town of Navaconcejo, within the province of Cáceres in the Extremadura region of Spain. The facility serves a population of approximately 3,500 residents, reflecting its role as a small-scale municipal treatment works in a rural inland setting. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity of 3,500 m³/day matches the population served, indicating a balanced infrastructure for the local community. The treated effluent is discharged into the local water environment, which ultimately drains into the Tagus River basin, one of the Iberian Peninsula's major river systems. The plant's operation helps protect downstream water quality and supports the ecological health of the region's freshwater resources.

The plant discharges into the local watershed that feeds into the Jerte River, a tributary of the Tagus River. The Tagus River flows westward through Spain and Portugal before reaching the Atlantic Ocean near Lisbon. The receiving waters support diverse aquatic life and are important for regional biodiversity, including migratory fish species. The plant's secondary treatment helps reduce organic pollution and nutrient loads, contributing to the ecological balance of the downstream river system.
