CANET LO ROIG Wastewater Treatment Plant, Canet lo Roig, Spain

The CANET LO ROIG wastewater treatment plant is located in Canet lo Roig, a municipality in the Baix Maestrat region of Castellón, Comunitat Valenciana, Spain. The plant serves a population of approximately 937 residents, reflecting its role in managing domestic wastewater for this small inland community. The facility operates with secondary treatment, which is the standard biological treatment level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 10,000. The plant has a designed capacity of 2000 m³/day and currently treats a daily volume of about 123.66 m³, indicating ample capacity for current demand. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Mediterranean Sea via the Cenia River or nearby coastal streams. The plant's operation helps protect the region's water quality and supports the ecological health of downstream water bodies, including the coastal waters of the Valencian Community.

The plant discharges into the local river system that flows into the Mediterranean Sea, contributing to the water quality of the coastal environment. The region supports diverse aquatic life and is part of a semi-arid Mediterranean climate where water resources are particularly sensitive. The treatment plant plays a key role in preventing nutrient pollution and safeguarding downstream ecosystems, including the marine habitats along the Costa del Azahar.
