PATERNA TERRAMELAR Wastewater Treatment Plant, Paterna, Spain

PATERNA TERRAMELAR is a former wastewater treatment plant located in Paterna, within the Comunitat Valenciana region of eastern Spain. The plant was designed to serve the local urban population and is now closed, reflecting changes in regional wastewater infrastructure. As a secondary treatment facility, it would have met the standards required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland agglomerations. The plant's designed capacity of 2,266 m³/day indicates it was sized for a medium-scale community, typical of suburban areas near Valencia. The plant's treated effluent would have discharged into local watercourses that drain toward the Mediterranean Sea. The region's water resources are ecologically sensitive, supporting diverse aquatic life and agricultural irrigation. Proper wastewater treatment is essential to protect downstream water quality and coastal ecosystems.

The plant is located in the Turia River basin, which flows through Valencia and into the Mediterranean Sea. The downstream environment includes coastal wetlands and marine habitats that depend on good water quality. Secondary treatment helps reduce organic pollution and protect these ecosystems from eutrophication and other impacts.
