Vallanca Wastewater Treatment Plant: Serving Vallanca, Comunitat Valenciana, Spain

The Vallanca wastewater treatment plant is located in the municipality of Vallanca, within the El Rincón de Ademuz comarca of Valencia province, Comunitat Valenciana, Spain. It serves a population of 711, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is situated inland, far from the coast, and discharges treated water into local watercourses. The plant operates with secondary treatment, which is the standard required by the EU directive for freshwater discharges from agglomerations of this size. Its designed capacity is 2,000 m³/day, and the current discharge volume is 57.30 m³/day, indicating ample capacity for current loads. As a municipal facility, it is part of the regional wastewater infrastructure managed by the relevant water authority in Comunitat Valenciana. The treated effluent from the plant flows into the local river system, which is part of the Júcar River basin. The Júcar River ultimately drains into the Mediterranean Sea near Cullera. The plant plays a key role in protecting the water quality of the Júcar basin, supporting aquatic life and downstream uses such as irrigation and recreation.

The plant discharges into the Turia River basin, which flows eastward through the province of Valencia and empties into the Mediterranean Sea. The Turia River supports diverse aquatic ecosystems and is an important water resource for agriculture and urban areas. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting the river's ecological health and the coastal waters of the Mediterranean.
