MONROY Wastewater Treatment Plant, Monroy, Extremadura, Spain

The MONROY wastewater treatment plant is located in the town of Monroy, within the province of Cáceres in the Extremadura region of Spain. This facility serves a population of approximately 2,200 residents, making it a small-scale municipal treatment plant. The plant is situated inland, away from coastal areas, and operates under Spain's national water regulations which align with European Union directives. 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. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 3,200 cubic meters per day and currently treats an average daily flow of 398.74 cubic meters, indicating significant spare capacity. The treated effluent from the MONROY plant is discharged into a local watercourse that ultimately flows into the Tagus River basin, one of the major river systems in the Iberian Peninsula. The Tagus River drains into the Atlantic Ocean near Lisbon, Portugal. The plant's operations help protect the local aquatic environment and downstream water quality in the Tagus basin, which supports diverse ecosystems and agricultural activities.

The MONROY plant discharges into a tributary of the Tagus River basin, which flows westward through Spain and Portugal to the Atlantic Ocean. The Tagus basin supports important aquatic habitats and is a vital water resource for agriculture and urban areas. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting downstream ecosystems from eutrophication and maintaining water quality for biodiversity.
