FALSET Wastewater Treatment Plant, Falset, Catalunya, Spain

The FALSET wastewater treatment plant is located in Falset, a town in the Priorat region of Tarragona, Catalunya, Spain. It serves a population of 2,084, making it a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, more than 10 km from the coast, and its treated effluent is discharged into the local river system. As a secondary treatment facility, FALSET meets the minimum standard required by the EU UWWTD for agglomerations of this size. The plant has a designed capacity of 3,082 m³/day and currently treats an average daily volume of 381.35 m³, indicating significant spare capacity. This operational context reflects the plant's role in managing domestic wastewater from the town and surrounding area. The treated water from FALSET ultimately drains into the Ebro River basin, which flows into the Mediterranean Sea. The Ebro Delta is an ecologically sensitive area that supports diverse aquatic life and important migratory bird populations. By providing secondary treatment, the plant helps protect downstream water quality and the ecological health of the Ebro River system.

FALSET's treated effluent enters the local stream network, which feeds into the Ebro River basin. The Ebro River flows southeast through Catalunya and discharges into the Mediterranean Sea via the Ebro Delta, a large wetland complex that supports diverse aquatic life and serves as a critical stopover for migratory birds. Secondary treatment at FALSET reduces organic pollutants and suspended solids, helping to maintain water quality in this ecologically important watershed.
