DOMENO Wastewater Treatment Plant, Domeño, Comunitat Valenciana, Spain

DOMENO is a wastewater treatment plant located in Domeño, a municipality in the Comunitat Valenciana region of eastern Spain. The plant serves a population of approximately 818 residents and is situated inland, more than 10 km from the coast. It operates as part of the regional wastewater infrastructure managed by the Valencian government. 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 with a population equivalent (PE) between 2,000 and 10,000. With a designed capacity of 2000 m³/day, the plant is appropriately sized for its service area. The actual discharge volume is 150.83 m³/day, indicating a utilization rate well below capacity. The treated effluent is discharged into a local watercourse that ultimately drains into the Mediterranean Sea. The plant plays a key role in protecting the region's water resources, particularly the Turia River basin, which supports agricultural activities and natural habitats. By ensuring proper treatment, DOMENO helps maintain water quality in downstream ecosystems.

The plant discharges into a local stream that flows into the Turia River, which then reaches the Mediterranean Sea near Valencia. The Turia River basin supports diverse aquatic life and is an important water source for irrigation in the region. The Mediterranean coastal waters are ecologically sensitive, hosting seagrass meadows and marine biodiversity. Proper wastewater treatment is essential to prevent nutrient enrichment and protect these habitats.
