RIBA ROJA SETRECE Wastewater Treatment Plant, Loriguilla, Comunitat Valenciana

RIBA ROJA SETRECE is a wastewater treatment plant located in Loriguilla, within the Camp de Túria comarca of Valencia, Spain. The plant serves a population of approximately 18,406, classifying it as a medium-sized agglomeration under EU regulations. It is situated inland, more than 50 km from the coast, and its operations are part of the broader water management infrastructure of the Comunitat Valenciana. As a plant serving a population between 10,000 and 100,000, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum standard. The designed capacity is reported as 1.00 (likely in thousands of cubic meters per day), indicating a facility sized to handle the organic load from the served population. The regulatory framework ensures compliance with discharge standards. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Mediterranean Sea via the Turia River basin. The plant plays a key role in protecting downstream water quality, including the Albufera de València, a coastal lagoon of ecological importance. By treating wastewater before release, it helps prevent eutrophication and supports aquatic life in the region's rivers and coastal waters.

The plant discharges into the Turia River basin, which flows eastward to the Mediterranean Sea. The downstream environment includes the Albufera de València, a coastal lagoon that supports diverse aquatic life and is an important migratory corridor for birds. The plant's treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the lagoon and coastal waters.
