ORIHUELA TORREMENDO Wastewater Treatment Plant, Orihuela, Comunitat Valenciana

ORIHUELA TORREMENDO is an advanced wastewater treatment plant located in the Torremendo area of Orihuela, within the Comunitat Valenciana region of Spain. The facility serves a small population of 906 residents and is designed to handle up to 2,500 cubic meters of wastewater per day, with a current discharge volume of approximately 119.74 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a Spanish facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. For small agglomerations like this, advanced treatment ensures compliance with stringent environmental standards. The treated effluent is discharged into the local water system, which ultimately drains into the Mediterranean Sea via the Segura River basin. The plant plays a key role in protecting the downstream aquatic environment, including the Segura River and its associated wetlands, which support diverse wildlife and are important for regional biodiversity.

The plant discharges into the Segura River basin, which flows into the Mediterranean Sea near Guardamar del Segura. The Segura River and its delta support a variety of aquatic life and are part of a semi-arid region where water resources are critical. The advanced treatment helps reduce nutrient loading, protecting downstream ecosystems from eutrophication and maintaining water quality for agricultural and recreational uses.
