AYNA Wastewater Treatment Plant, Aýna, Castilla-La Mancha, Spain

AYNA is an advanced wastewater treatment plant located in Aýna, a small town in the province of Albacete, Castilla-La Mancha, Spain. The plant serves a population of approximately 1,158 residents, reflecting its role in managing domestic wastewater for this rural community. As an advanced treatment facility, AYNA goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. This level of treatment is typical for plants in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for discharges into sensitive catchments. The treated wastewater from AYNA is discharged into the local hydrological network, which ultimately drains into the Segura River basin and reaches the Mediterranean Sea. By providing advanced treatment, the plant helps protect downstream water quality and supports the ecological health of the region's rivers and coastal waters.

AYNA discharges into the Segura River basin, which flows through southeastern Spain and empties into the Mediterranean Sea. The region's semi-arid climate makes water resources particularly sensitive to pollution. Advanced treatment at this plant helps safeguard the ecological balance of local streams and the downstream Segura River, which supports diverse aquatic life and is important for irrigation and drinking water supply.
