Morella Wastewater Treatment Plant | Secondary Treatment in Comunitat Valenciana

The Morella wastewater treatment plant is located in the town of Morella, within the Comunitat Valenciana region of eastern Spain. It serves a population of approximately 3,272 residents, making it a small agglomeration under EU classification. The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 8,666 m³/day, and the current discharge volume is 517.54 m³/day, indicating ample reserve capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Mediterranean Sea via the Ebro River basin or nearby coastal rivers. The plant plays a key role in protecting the local environment by reducing nutrient and pollutant loads, supporting water quality in the region's rivers and downstream ecosystems.

The Morella plant discharges into local streams that are part of the broader Ebro River basin, which flows into the Mediterranean Sea. The region's watershed supports diverse aquatic life and is important for agricultural water use downstream. The plant's secondary treatment helps mitigate eutrophication risks in the receiving waters, contributing to the ecological health of the Mediterranean coastal zone.
