ROSALEJO Wastewater Treatment Plant, Rosalejo, Extremadura, Spain

ROSALEJO is a wastewater treatment plant located in Rosalejo, a town in the province of Cáceres, Extremadura, Spain. The facility serves a population of approximately 3,300 people and has a designed capacity of 2,800 cubic meters per day, with an actual discharge volume of 598.12 cubic meters per day. As a secondary treatment plant, ROSALEJO meets the minimum treatment requirements under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 in freshwater areas, which applies here. The plant's treated effluent is discharged into a local watercourse that ultimately drains into the Tagus River basin, one of the major river systems in the Iberian Peninsula. The Tagus River flows westward through Spain and Portugal, emptying into the Atlantic Ocean near Lisbon. The plant plays a role in protecting local water quality and downstream ecosystems.

The plant discharges into a tributary of the Tagus River basin, which flows through central Spain and Portugal to the Atlantic Ocean. The Tagus River supports diverse aquatic life and is an important water resource for agriculture and urban areas. The plant's secondary treatment helps reduce organic pollutants and protect the ecological health of the receiving water body.
