FLIX Wastewater Treatment Plant, Flix, Catalunya, Spain

FLIX is a municipal wastewater treatment plant located in Flix, a town in the Ribera d'Ebre comarca of Tarragona, Catalunya, Spain. The plant serves a population of around 2,848 residents and is part of the region's water management infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 12,928 m³/day and a current discharge volume of 863.12 m³/day, the plant operates well below its capacity, indicating room for future growth. As a Spanish facility, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas. The treated effluent from FLIX is discharged into the local water environment, ultimately contributing to the Ebro River basin. The Ebro River is one of Spain's major rivers, flowing into the Mediterranean Sea via the Ebro Delta, an ecologically significant area that supports diverse aquatic life and migratory birds. The plant's advanced treatment helps protect downstream water quality and the sensitive delta ecosystem.

FLIX discharges into the Ebro River basin, which flows through Catalunya and into the Mediterranean Sea via the Ebro Delta. The delta is a critical habitat for numerous bird species and supports extensive rice farming. Advanced treatment at the plant reduces nutrient loads, helping to prevent eutrophication in the river and coastal waters.
