Overview
OLLONIEGO wastewater treatment plant serves the Olloniego area of Oviedo, Asturias, Spain. Designed for a capacity of 1.00, it supports a population of approximately 3,000.
The OLLONIEGO wastewater treatment plant is located in the Olloniego parish of Oviedo, within the autonomous community of Asturias, Spain. This facility serves a population of around 3,000 residents, making it a small-scale municipal treatment plant in the region. As a plant in Spain, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment to meet receiving water quality standards, typically secondary treatment or equivalent. The plant's treated effluent is discharged into local watercourses that eventually drain into the Cantabrian Sea. The surrounding area is characterized by the Nalón River basin, which supports diverse aquatic life and is important for regional water resources. The plant plays a key role in protecting local streams and downstream ecosystems from untreated wastewater.
Environmental context
The plant discharges into the Nalón River basin, which flows northward through Asturias and empties into the Cantabrian Sea. This coastal region supports diverse aquatic habitats and is important for migratory fish species. The treatment plant helps maintain water quality in the river system, reducing nutrient and pathogen loads that could affect downstream ecological health and recreational uses.
