NAVALAGAMELLA Wastewater Treatment Plant, Navalagamella, Spain

The NAVALAGAMELLA wastewater treatment plant is located in Navalagamella, a municipality in the Comunidad de Madrid, Spain. It serves a population of approximately 2,177 residents, classifying it as a small agglomeration under Spanish and EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. 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 4,000 m³/day, with a reported discharge volume of 478.69 m³/day, indicating operational headroom. As a municipal facility, it is subject to Spanish national regulations that transpose EU directives, ensuring compliance with effluent quality standards. The treated effluent is discharged into local watercourses that ultimately drain into the Tagus River basin, a major hydrological system in central Spain. The Tagus River flows westward through Portugal to the Atlantic Ocean. The plant plays a key role in protecting the local aquatic environment and downstream water quality in the Tagus basin, which supports diverse ecosystems and agricultural activities.

The plant discharges into the Tagus River basin, which drains into the Atlantic Ocean via Portugal. The receiving water bodies support aquatic life and are used for irrigation and recreation. The region's Mediterranean climate with seasonal droughts makes treated wastewater reuse and water quality protection important for maintaining ecological balance in the basin.
