Valencia del Ventoso Wastewater Treatment Plant | Secondary Treatment, Extremadura

Valencia del Ventoso wastewater treatment plant is located in the municipality of Valencia del Ventoso, in the province of Badajoz, Extremadura, Spain. The plant serves a population of approximately 4,200 residents, making it a small to medium-sized facility within the region. The plant operates with secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity is 5,700 m³/day, and the current discharge volume is 761.24 m³/day, indicating ample capacity for current loads. The treated effluent is discharged into local watercourses that eventually drain into the Guadiana River basin, which flows into the Gulf of Cádiz (Atlantic Ocean). The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from untreated wastewater.

The plant discharges into the Guadiana River basin, which flows southwest through Extremadura and into the Gulf of Cádiz. The Guadiana River supports diverse aquatic life and is an important migratory corridor for fish species. The secondary treatment provided helps reduce organic pollution and protect the ecological health of the river and its estuary.
