MACASTRE Wastewater Treatment Plant, Macastre, Comunitat Valenciana

The MACASTRE wastewater treatment plant is located in Macastre, a municipality in the Comunitat Valenciana, Spain. The plant serves a population of approximately 4,906 residents and is part of the region's municipal wastewater infrastructure. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The designed capacity is 2,000 m³ per day, with a reported discharge volume of 185.76 m³/day. The treated effluent is discharged into the local watershed, which ultimately drains into the Mediterranean Sea. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's rivers and coastal environment.

The MACASTRE plant discharges into the Turia River basin, which flows eastward to the Mediterranean Sea near Valencia. The downstream environment includes the Albufera de Valencia, a coastal lagoon of high ecological importance that supports diverse aquatic life and migratory birds. The plant's secondary treatment helps reduce nutrient and organic loads entering this sensitive ecosystem.
