The facility serves a population equivalent of 136,915, classifying it as a large agglomeration under EU regulations. As a large agglomeration in a sensitive area, the plant is expected to provide at least secondary treatment, and likely tertiary treatment to meet nutrient removal standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant's designed capacity is 1. Typical capacities for this scale range from 30,000 to 50,000 m³/day. The plant discharges into the Besòs River, which flows through the Barcelona metropolitan area and ultimately reaches the Mediterranean Sea. The Besòs basin supports diverse aquatic life and is an important ecological corridor in the region, with efforts ongoing to improve water quality and restore riparian habitats.
