Torremocha Wastewater Treatment Plant, Torremocha, Extremadura, Spain

Torremocha wastewater treatment plant is located in the municipality of Torremocha, in the province of Cáceres, Extremadura, Spain. The plant serves a population of approximately 2,700 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 minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity of 3,335 m³/day indicates the plant is sized to handle peak flows, while the current discharge volume of 489.37 m³/day suggests it operates well below capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. 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 downstream river system, which is important for agriculture and biodiversity in the region.

The plant discharges into a local stream that is part of the Tagus River basin, one of the major river systems in the Iberian Peninsula. The Tagus River flows through central Spain and Portugal, eventually reaching the Atlantic Ocean near Lisbon. The downstream environment supports diverse aquatic life and is used for irrigation and recreation. Secondary treatment helps reduce nutrient loads and organic pollution, mitigating eutrophication risks in the river and its estuary.
