Pedralba wastewater treatment plant is located in the municipality of Pedralba, within the La Serranía comarca of the Comunitat Valenciana, Spain. The plant serves a population of approximately 3,571 residents and is designed with a capacity of 3,500 m³/day, with a reported discharge volume of 847.37 m³/day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. For populations between 2,000 and 10,000, secondary treatment is mandated, and the plant's capacity aligns with this regulatory framework. The treated effluent is discharged into the local water system, which ultimately drains into the Mediterranean Sea via the Turia River basin. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's rivers and coastal waters.

Environmental context

The plant discharges into the Turia River basin, which flows eastward to the Mediterranean Sea near Valencia.
