LINYOLA Wastewater Treatment Plant, Linyola, Catalunya, Spain

The LINYOLA wastewater treatment plant is located in Linyola, a municipality in the Pla d'Urgell region of Catalunya, Spain. The plant serves a population of approximately 1,458 residents, reflecting its role in managing domestic wastewater for this small inland community. As a plant in Spain, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive aims to protect water quality across the European Union, and plants serving fewer than 2,000 population equivalents are subject to appropriate treatment requirements based on the sensitivity of the receiving environment. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Ebro River basin, one of the most important river systems in Spain. The Ebro River flows into the Mediterranean Sea, supporting diverse aquatic ecosystems and agricultural activities along its course. The plant's operation contributes to protecting these downstream environments from nutrient pollution and other contaminants.

The plant discharges into local streams that are part of the Ebro River basin, which flows into the Mediterranean Sea. The Ebro Delta is an ecologically significant area that supports diverse bird populations and aquatic life. Proper wastewater treatment is essential to prevent eutrophication and maintain water quality in this sensitive coastal ecosystem.
