Overview
CASSERRES is a secondary wastewater treatment plant serving the town of Casserres in Catalunya, Spain. It treats wastewater from a population of about 1,381 with a designed capacity of 2,201 m³/day.
CASSERRES is a municipal wastewater treatment plant located in Casserres, a town in the Berguedà comarca of Barcelona, Catalunya, Spain. The plant serves a population of approximately 1,381 and is part of the region's wastewater infrastructure managed under Spanish and European regulations. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,201 m³/day and an average discharge volume of 600.39 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Llobregat River basin. The Llobregat River flows through Catalunya and discharges into the Mediterranean Sea near Barcelona. The plant plays a key role in protecting the Llobregat River and the downstream coastal environment from untreated wastewater pollution.
Environmental context
The plant discharges into the Llobregat River basin, which flows through the Berguedà region and eventually reaches the Mediterranean Sea. The Llobregat River supports diverse aquatic life and is an important water resource for the region. Downstream, the river passes through agricultural and urban areas before entering the sea, making the plant's secondary treatment essential for reducing organic load and protecting both freshwater and marine ecosystems.
