ALMOROX Wastewater Treatment Plant, Almorox, Castilla-La Mancha, Spain

ALMOROX is a wastewater treatment plant located in Almorox, a municipality in the province of Toledo, Castilla-La Mancha, Spain. The plant serves a population of approximately 3,552 people, placing it in the small agglomeration category under Spanish and EU regulations. The facility employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment is typically implemented in sensitive areas or where higher effluent quality is needed to protect receiving waters. The treated wastewater is discharged at a volume of 750 m³/day into the local hydrological network, which ultimately drains into the Tagus River basin. The Tagus River is the longest river in the Iberian Peninsula and flows into the Atlantic Ocean near Lisbon. The advanced treatment helps protect downstream aquatic ecosystems and water quality.

The plant discharges into the Tagus River basin, which flows westward through central Spain and Portugal before reaching the Atlantic Ocean. The Tagus supports diverse aquatic life and provides water for agriculture and urban areas. Advanced treatment at ALMOROX reduces nutrient and pollutant loads, helping to maintain ecological balance in the river and its estuary.
