The DELTEBRE wastewater treatment plant is located in Deltebre, a municipality in the Baix Ebre region of Tarragona, Catalunya, Spain. The plant serves a population of approximately 11,394 residents, classifying it as a medium-sized agglomeration under European Union standards. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The plant discharges treated wastewater into the Ebro River delta, a ecologically significant area that supports diverse aquatic life and important migratory bird populations. The Ebro River flows into the Mediterranean Sea, making the plant's operations critical for protecting downstream coastal and marine environments.

The DELTEBRE plant is situated in the Ebro River delta, one of the most important wetland areas in the western Mediterranean. The delta supports a rich ecosystem of aquatic plants, fish, and birds, and is a key stopover for migratory species. Treated effluent from the plant flows into the Ebro River, which then discharges into the Mediterranean Sea, influencing coastal water quality and marine habitats.
