PERALADA Wastewater Treatment Plant, Peralada, Catalunya, Spain

PERALADA wastewater treatment plant is located in Peralada, a municipality in the Alt Empordà region of Girona, Catalunya, Spain. The plant serves a population of around 2,908 and is designed to handle up to 4,002 m³ of wastewater per day, with an average discharge volume of 413.29 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a facility in Spain, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for discharges into sensitive areas. The plant's advanced treatment level aligns with the directive's standards for protecting water quality. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The plant plays a key role in safeguarding the region's water resources, supporting both ecological health and human activities downstream. Its advanced treatment helps reduce nutrient loading and protect coastal waters.

The plant discharges into the local river system, which flows through the Alt Empordà region and eventually reaches the Mediterranean Sea near the Gulf of Roses. This coastal area supports diverse marine life and is ecologically sensitive due to its proximity to the Aiguamolls de l'Empordà wetlands, an important habitat for migratory birds. Advanced treatment at PERALADA helps minimize nutrient and pollutant inputs, protecting the downstream aquatic ecosystem and the marine environment.
