Overview
Bourg madame Puigcerda is a wastewater treatment plant serving Puigcerdà, Catalunya, Spain. It treats wastewater for approximately 6,300 people in the Cerdanya region.
Bourg madame Puigcerda is a wastewater treatment plant located in Puigcerdà, within the province of Girona in Catalunya, Spain. The plant serves a population of approximately 6,300 residents in the Cerdanya comarca, a mountainous area in the eastern Pyrenees near the French border. As a plant serving a small agglomeration in Spain, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For settlements with a population equivalent between 2,000 and 10,000, the directive requires appropriate treatment, typically secondary treatment, to protect receiving waters. The plant's treatment process and capacity are consistent with these regulatory expectations. The treated effluent is discharged into local watercourses that drain into the Segre River, a major tributary of the Ebro River, which ultimately flows into the Mediterranean Sea. The plant plays a key role in protecting the headwaters of this important basin, supporting aquatic ecosystems and water quality in the Pyrenean region.
Environmental context
The plant discharges into the Segre River basin, which flows through the Cerdanya valley and joins the Ebro River before reaching the Mediterranean Sea. This headwater region supports diverse aquatic life, including native fish species and macroinvertebrates sensitive to pollution. The mountainous terrain and seasonal snowmelt influence flow regimes, making consistent treatment essential for maintaining ecological balance downstream.
