Torrebaja Wastewater Treatment Plant, Ademuz, Comunitat Valenciana

Torrebaja is a wastewater treatment plant located near Ademuz in the Rincón de Ademuz region of Comunitat Valenciana, Spain. The facility serves a population of approximately 1,949 people, making it a small-scale municipal plant in a rural inland area. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. Secondary treatment typically involves biological oxidation and sedimentation to reduce organic matter and suspended solids. The plant has a designed capacity of 2,708 cubic meters per day and currently discharges an average of 202.73 cubic meters per day. The treated effluent is discharged into a local watercourse within the Turia River basin, which flows eastward through Valencia and into the Mediterranean Sea. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from untreated sewage, supporting water quality in the Turia River and its tributaries.

The plant discharges into a tributary of the Turia River, which flows through the province of Valencia and empties into the Mediterranean Sea near the city of Valencia. The Turia River supports diverse aquatic life and is an important ecological corridor in the region. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding water quality in the river and its downstream coastal environment.
