RIBESALBES Wastewater Treatment Plant, Ribesalbes, Comunitat Valenciana, Spain

RIBESALBES wastewater treatment plant is located in Ribesalbes, a municipality in the province of Castellón, within the Comunitat Valenciana region of eastern Spain. The plant served the local population before its closure, operating under Spain's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). As a secondary treatment facility, RIBESALBES provided biological treatment to reduce organic matter and suspended solids. The plant's designed capacity of 1,808 m³/day indicates it was sized for a small agglomeration. Under the EU directive, secondary treatment is the minimum standard for inland freshwater discharges. The plant's treated effluent would have discharged into a local watercourse, likely a tributary of the Mijares River basin, which flows into the Mediterranean Sea. The region's coastal and inland waters support diverse aquatic life, and proper treatment helps protect downstream ecosystems.

RIBESALBES is situated inland in the Mijares River basin, which drains into the Mediterranean Sea near Castellón de la Plana. The receiving water body, likely a small stream or river, supports local aquatic habitats and contributes to the ecological health of the coastal zone. The plant's secondary treatment helped reduce nutrient and organic pollution, safeguarding water quality in the downstream environment.
