BAJO EGA Wastewater Treatment Plant, San Adrián, Navarra, Spain

BAJO EGA is a wastewater treatment plant located in San Adrián, within the province of Navarra, Spain. Serving a population equivalent of 50,410, it is classified as a medium agglomeration under EU regulations. The plant is situated near the Ebro River basin, a major watercourse in northeastern Spain. As a facility in Spain, BAJO EGA operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations between 10,000 and 150,000 population equivalent. For larger agglomerations discharging into sensitive areas, tertiary treatment may be mandated. The regulatory framework ensures compliance with European standards for wastewater treatment. The plant's treated effluent likely discharges into the Ebro River or its tributaries, which flow into the Mediterranean Sea via the Ebro Delta. The Ebro Delta is an ecologically significant area supporting diverse aquatic life and migratory bird populations. Proper treatment at BAJO EGA helps protect downstream water quality and the sensitive coastal ecosystem.

BAJO EGA discharges into the Ebro River basin, which drains into the Mediterranean Sea through the Ebro Delta. The delta is a critical habitat for numerous bird species and supports rich biodiversity. The plant's operations help maintain water quality in this ecologically sensitive region, preventing nutrient pollution that could lead to eutrophication in the coastal zone.
