Overview
FOLGUEROLES wastewater treatment plant serves the municipality of Folgueroles in Catalunya, Spain. It provides secondary treatment for a population of 1,685 with a designed capacity of 2,500 m³/day.
The FOLGUEROLES wastewater treatment plant is located in the municipality of Folgueroles, in the Osona region of Barcelona, Catalunya, Spain. It serves a population of approximately 1,685 people, making it a small-scale facility within the regional wastewater infrastructure. The plant is situated inland, more than 10 km from the coast, and its operations are part of the broader water management network in the Ter River basin. As a secondary treatment facility, FOLGUEROLES employs biological processes to remove organic matter and suspended solids from wastewater. The plant has a designed capacity of 2,500 m³/day, with a reported discharge volume of 696.87 m³/day, indicating it operates well below its maximum capacity. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like Folgueroles (under 2,000 population equivalent) are required to provide appropriate treatment, and secondary treatment meets this standard for inland freshwater discharge. The treated effluent from FOLGUEROLES is discharged into local watercourses that eventually drain into the Ter River, which flows into the Mediterranean Sea near the Costa Brava. The Ter River supports diverse aquatic life and is an important water resource for the region. The plant's secondary treatment helps protect downstream water quality and the ecological health of the river and coastal environment.
Environmental context
The FOLGUEROLES plant discharges into local streams that feed the Ter River basin, which flows southeast into the Mediterranean Sea. The Ter River is a key watercourse in Catalunya, supporting agricultural irrigation, drinking water supplies, and a variety of freshwater species. Downstream, the river passes through the Baix Ter wetlands, an ecologically sensitive area that provides habitat for migratory birds and aquatic flora. The plant's secondary treatment reduces organic pollution and nutrient loads, helping to maintain the ecological balance of the river and its coastal discharge zone.
