GANDESA Wastewater Treatment Plant, Gandesa, Catalunya, Spain

GANDESA is a wastewater treatment plant located in Gandesa, a municipality in the comarca of Terra Alta, Tarragona, Catalunya, Spain. The plant serves a population of 3,110 and is part of the region's municipal wastewater infrastructure. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 7,540 cubic meters per day and an actual discharge volume of 451.12 cubic meters per day, the plant operates well below its capacity. As a Spanish facility, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The treated effluent is discharged into the local watershed, which ultimately drains into the Ebro River basin. The Ebro River flows into the Mediterranean Sea, supporting diverse aquatic life and providing water for agriculture and ecosystems in the region. The plant's advanced treatment helps protect downstream water quality and the ecological health of the Ebro Delta, a critical wetland area.

The plant discharges into the Ebro River basin, which flows into the Mediterranean Sea via the Ebro Delta. The delta is an ecologically sensitive area that supports diverse aquatic life, including fish and bird species, and is an important migratory corridor. Advanced treatment at the plant helps reduce nutrient loading and protect downstream water quality.
