EDAR Parque La Reina - Secondary Wastewater Treatment Plant in Arona, Canary Islands

EDAR Parque La Reina is a municipal wastewater treatment plant located in the Parque de la Reina area of Arona, on the island of Tenerife in the Canary Islands, Spain. The plant serves a population of approximately 3,283 residents and is part of the region's water infrastructure managed under Spanish and European regulations. 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. With a designed capacity of 12,000 m³/day and an actual discharge volume of 595.04 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local environment, likely into the Atlantic Ocean given the plant's coastal location on Tenerife. The Canary Islands rely on wastewater treatment to protect marine ecosystems and coastal waters, which are vital for tourism and biodiversity. The plant plays a key role in maintaining water quality in the region.

The plant is located within 10 km of the coast on the southern shore of Tenerife, part of the Canary Islands. Treated wastewater likely discharges into the Atlantic Ocean, which supports diverse marine life including sea turtles and cetaceans. The coastal waters are ecologically sensitive due to tourism and fishing pressures, making effective treatment essential to prevent nutrient enrichment and protect coral reef habitats.
