NAVALAFUENTE Wastewater Treatment Plant, Navalafuente, Comunidad de Madrid

The NAVALAFUENTE wastewater treatment plant is located in the municipality of Navalafuente, within the Comunidad de Madrid, Spain. It serves a small population of 614 residents, reflecting the rural character of the area. The plant is situated inland, away from coastal zones, and its operations are part of the regional water management infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Although the designed capacity is 6,300 m³/day, the actual discharge volume is 667.37 m³/day, indicating that the plant operates well below its capacity. This suggests that the infrastructure is sized for future growth or seasonal peaks. The treated effluent is discharged into local watercourses that eventually drain into the Tagus River basin, which flows westward through Spain and into Portugal, reaching the Atlantic Ocean near Lisbon. The plant plays a role in protecting the local streams and the downstream aquatic ecosystems from untreated pollution.

The plant discharges into small streams within the Tagus River basin, which ultimately flows into the Atlantic Ocean. The local watershed supports diverse aquatic life and is part of a region with Mediterranean climate, where water resources are seasonally stressed. Proper treatment helps maintain water quality in the downstream river system, which is important for both ecological health and human uses such as irrigation and recreation.
