COVES DE VINROMA Wastewater Treatment Plant, les Coves de Vinromà, Comunitat Valenciana

COVES DE VINROMA is a municipal wastewater treatment plant located in les Coves de Vinromà, a town in the province of Castellón, Comunitat Valenciana, Spain. The plant serves a population of 1,275 and operates with secondary treatment, which is the standard biological treatment for organic matter removal. Its designed capacity is 4,093 m³/day, with an actual discharge volume of 405.93 m³/day, indicating significant spare capacity. As a small agglomeration, the plant falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland populations between 2,000 and 10,000 population equivalent (PE). Although the served population is below 2,000, the plant's secondary treatment exceeds the minimum requirement for its size, ensuring compliance with European standards. The plant is operated as part of Spain's municipal wastewater infrastructure, regulated by the Confederación Hidrográfica del Júcar or the relevant regional authority. The treated effluent is discharged into a local watercourse that drains into the Mediterranean Sea via the coastal plains of Castellón. The plant plays a key role in protecting the region's water quality, particularly the nearby Rambla de la Viuda or similar ephemeral streams that flow into the Gulf of Valencia. Its operation supports the ecological health of the coastal environment and the agricultural areas that rely on these water bodies.

The plant discharges into a local stream that is part of the drainage network flowing toward the Mediterranean Sea, specifically the Gulf of Valencia. This coastal region supports diverse aquatic life and is important for migratory birds. The secondary treatment reduces organic pollutants, helping to maintain water quality in the downstream environment, which includes agricultural zones and sensitive coastal habitats.
