Overview
Cabo de Cruz Boiro wastewater treatment plant serves the municipality of Boiro in Galicia, Spain. It is located near the coast of the Ria de Arousa, an ecologically significant estuary.
The Cabo de Cruz Boiro wastewater treatment plant is a municipal facility serving the town of Boiro in the province of A Coruna, Galicia, Spain. With a population served of approximately 26,749, it is classified as a medium-sized agglomeration under European Union standards. The plant is situated in the coastal region of the Ria de Arousa, a large estuary on the Atlantic coast. As a Spanish wastewater treatment plant, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment as a minimum, with more stringent requirements if the discharge enters a sensitive area. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a moderate scale of operation. The treated effluent from the plant is discharged into the local environment, ultimately reaching the Ria de Arousa, a productive estuary that supports diverse marine life, including shellfish fisheries and migratory bird populations. The plant plays a key role in protecting the water quality of this ecologically important coastal ecosystem.
Environmental context
The plant discharges into the Ria de Arousa, a large estuary on the Atlantic coast of Galicia. This estuary is part of the broader Atlantic Ocean watershed and is known for its high biological productivity, supporting shellfish aquaculture and diverse marine habitats. The surrounding area is characterized by a rugged coastline and a temperate oceanic climate. The plant's operation is critical for maintaining water quality in this sensitive coastal environment, which is subject to both tidal influences and freshwater inputs from local rivers.
Frequently asked questions
The plant is located in Boiro, a municipality in the province of A Coruna, Galicia, Spain. Its address is Rua do Campo, Corvino, O Campo, O Castro, Boiro, A Barbanza, A Coruna, Galicia.
The plant serves approximately 26,749 people, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive.
The treated effluent is discharged into the local environment, ultimately reaching the Ria de Arousa estuary, which flows into the Atlantic Ocean.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), transposed into Spanish law. For agglomerations of this size, secondary treatment is required, with additional nutrient removal if the discharge is in a sensitive area.
Plants of this scale in Spain typically employ secondary biological treatment, such as activated sludge or trickling filters, to meet EU standards. Some may include tertiary treatment for nutrient removal if discharging into sensitive coastal waters.
