BENIARRES Wastewater Treatment Plant, Beniarrés, Comunitat Valenciana

BENIARRES is a wastewater treatment plant located in Beniarrés, a municipality in the Comunitat Valenciana region of Spain. The plant serves a population of approximately 2,598 people and is part of the region's municipal wastewater infrastructure. It is situated inland, more than 10 km from the coast, and operates under Spanish and EU regulatory frameworks. The plant employs advanced treatment processes, ensuring high-quality effluent before discharge. With a designed capacity of 2,000 m³/day and a current discharge volume of 187.58 m³/day, the plant operates well below its capacity. As a facility in Spain, it complies with the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size, but the plant exceeds this requirement with advanced treatment. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The plant plays a key role in protecting the Serpis River basin and downstream ecosystems, including coastal areas. By providing advanced treatment, it helps maintain water quality and supports aquatic life in the region.

The plant discharges into the Serpis River basin, which flows into the Mediterranean Sea near the Costa Blanca. This coastal area supports diverse marine life and is ecologically sensitive. Advanced treatment at the plant reduces nutrient loads, helping to prevent eutrophication and protect the downstream aquatic environment.
