ALMOHARIN Wastewater Treatment Plant, Almoharín, Extremadura, Spain

ALMOHARIN is a wastewater treatment plant located in Almoharín, a municipality in the province of Cáceres, Extremadura, Spain. The plant serves a population of approximately 4,700 residents, reflecting the scale of a small agglomeration under EU classification. 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 4,320 cubic meters per day indicates the plant's infrastructure is sized to handle peak flows, while the average daily discharge volume of 851.86 cubic meters suggests current utilization is well below capacity. The 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 flows westward through Spain and Portugal before reaching the Atlantic Ocean near Lisbon. The plant's operation helps protect the local aquatic ecosystem and downstream water quality in the Tagus basin.

The plant discharges into a tributary of the Tagus River, which flows through central Spain and Portugal to the Atlantic Ocean. The Tagus basin supports diverse aquatic life and is an important water resource for agriculture and urban supply. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain ecological balance in the receiving waters.
