AYORA Wastewater Treatment Plant, Ayora, Comunitat Valenciana, Spain

The AYORA wastewater treatment plant is located in Ayora, within the Comunitat Valenciana region of Spain. It serves a population of approximately 9,571 people, making it a medium-sized agglomeration under Spanish and EU regulations. The plant is situated inland, away from coastal areas, and treats municipal wastewater from the local community. The plant operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size discharging into freshwater. The designed capacity is 10,000 m³/day, and the current discharge volume is 921.19 m³/day, indicating operational capacity well within design limits. The treated effluent is discharged into a local watercourse, likely part of the Júcar River basin, which flows into the Mediterranean Sea. The plant plays a key role in protecting the local watershed from nutrient pollution and organic load, supporting downstream aquatic ecosystems and water quality in the region.

The plant discharges into a tributary of the Júcar River, which flows eastward to the Mediterranean Sea near Valencia. The Júcar basin supports diverse aquatic life and is used for irrigation and drinking water supply. Secondary treatment reduces organic matter and suspended solids, helping to prevent eutrophication in downstream waters and maintain ecological balance in the river system.
