Cella Wastewater Treatment Plant, Cella, Aragón, Spain

The Cella wastewater treatment plant is located in the town of Cella, within the province of Teruel in the autonomous community of Aragón, Spain. It serves a population of 2,915 and is designed to handle a capacity of 6,000 m³ per day, with an average discharge volume of 528.34 m³/day. The plant provides secondary treatment, which is the standard level required under the European Union's Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring that the effluent meets quality standards before discharge. The treated wastewater is discharged into the local hydrological network, which ultimately drains into the Ebro River basin. The Ebro River is one of Spain's major rivers, flowing into the Mediterranean Sea. The plant's operations help protect the local water quality and downstream ecosystems, including the Ebro Delta, a region of ecological importance.

The Cella plant discharges into the Turia River basin, which flows into the Mediterranean Sea. The receiving waters support diverse aquatic life and are part of the broader Ebro River system. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding downstream habitats and water quality for agricultural and ecological uses.
