JERICA Wastewater Treatment Plant, Jérica, Comunitat Valenciana, Spain

The JERICA wastewater treatment plant is located in Jérica, a town in the Alt Palància comarca of Castellón province, Comunitat Valenciana, Spain. The plant serves a population of approximately 3,731 residents and is part of the region's municipal wastewater infrastructure. As a secondary treatment facility, JERICA operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The plant has a designed capacity of 8,341 m³/day, with a reported discharge volume of 477.61 m³/day, indicating it operates well below its design capacity. 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 region's water resources and downstream ecosystems, including the coastal waters of the Valencian Community.

The JERICA plant discharges into the Palància River basin, which flows eastward into the Mediterranean Sea near Sagunto. The river supports diverse aquatic life and is an important ecological corridor in the region. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting downstream water quality and marine habitats.
