ROSSELL Wastewater Treatment Plant, Rossell, Comunitat Valenciana, Spain

The ROSSELL wastewater treatment plant is located in Rossell, within the Comunitat Valenciana region of Spain. It serves a population of 1,259 and is part of the municipal wastewater infrastructure for this inland community. The plant is situated near the CV-100 road, in the Baix Maestrat comarca of Castellón province. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The designed capacity is 4,960 units, with a current discharge volume of 153.06 units, indicating ample capacity for future growth. The treated effluent is discharged into the local watershed, which ultimately drains to the Mediterranean Sea. The plant's advanced treatment helps protect downstream water quality in the region's rivers and coastal areas. The Comunitat Valenciana is known for its agricultural and tourism sectors, making water quality management crucial for both environmental and economic reasons.

The plant discharges into the local river system, which flows into the Mediterranean Sea. The region's watershed supports diverse aquatic life and is important for irrigation and recreation. Advanced treatment ensures that nutrient loads are minimized, reducing the risk of eutrophication in downstream coastal waters. The plant's location within 50 km of the coast means its effluent can influence nearshore marine environments.
