OLIVA OLIVA NOVA SECTOR 1 Wastewater Treatment Plant, Oliva, Spain

OLIVA OLIVA NOVA SECTOR 1 is a wastewater treatment facility located in Oliva, within the Comunitat Valenciana region of Spain. The plant serves a population of 2,830 and has a designed capacity of 3,409 m³/day, with an average discharge volume of 332.33 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Spain classifies sensitive areas requiring tertiary treatment; this plant's advanced level aligns with such requirements for coastal discharge. The treated effluent is discharged near the Mediterranean coast, less than 10 km from the shoreline. The plant plays a key role in protecting the coastal waters of the Gulf of Valencia and the nearby Albufera de València wetland ecosystem, which supports diverse aquatic life and migratory birds.

The plant discharges into the Mediterranean Sea near Oliva, within the Gulf of Valencia. The coastal waters are part of a sensitive marine environment that supports seagrass meadows and fish spawning grounds. Downstream, the Albufera de València lagoon, a major coastal wetland, relies on good water quality from upstream treatment plants to maintain its ecological balance. The advanced treatment helps reduce nutrient loading, preventing eutrophication in these coastal and lagoon ecosystems.
