ALPERA Wastewater Treatment Plant, Alpera, Castilla-La Mancha, Spain

The ALPERA wastewater treatment plant is located in Alpera, a municipality in the province of Albacete, Castilla-La Mancha, Spain. The plant serves a population of approximately 3,500 residents, providing advanced treatment to ensure high-quality effluent before discharge. As an advanced treatment facility, ALPERA goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent standards under Spanish and EU regulations. The plant operates under the framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size to protect receiving water bodies. The treated wastewater is discharged into local watercourses that eventually drain into the Júcar River basin, which flows into the Mediterranean Sea. The advanced treatment helps safeguard the ecological health of these waters, supporting aquatic life and downstream uses.

The plant discharges into local streams that are part of the Júcar River basin, which ultimately flows into the Mediterranean Sea. The region's semi-arid climate makes water quality management critical for sustaining local ecosystems and agricultural activities. Advanced treatment reduces nutrient loading, protecting downstream aquatic habitats and preventing eutrophication in sensitive coastal areas.
