SORT Wastewater Treatment Plant, Sort, Catalunya, Spain

The SORT wastewater treatment plant is located in Sort, a town in the comarca of Pallars Sobirà, in the province of Lleida, Catalunya, Spain. It serves a population of 1,319 and is part of the municipal wastewater infrastructure for the area. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. The designed capacity is 5,500 m³/day, and the actual discharge volume is 666.10 m³/day, indicating that the plant operates well below its capacity. The treated effluent is discharged into the local water environment, ultimately draining into the Noguera Pallaresa River, a tributary of the Segre River, which flows into the Ebro River and then into the Mediterranean Sea. The plant plays a key role in protecting the water quality of the Noguera Pallaresa and downstream ecosystems.

The SORT plant discharges into the Noguera Pallaresa River, which flows through the Pyrenees and joins the Segre River, a major tributary of the Ebro River. The Ebro River drains into the Mediterranean Sea via the Ebro Delta, an ecologically sensitive area that supports diverse aquatic life and important migratory bird populations. The plant's secondary treatment helps reduce organic pollution and protect the river's ecological health.
