Overview
ETAR del Polígono Industrial de Granadilla is a primary treatment plant in Arico, Canarias, Spain, serving a population of 2,931. It discharges 531.24 m³/day of treated wastewater near the coast.
ETAR del Polígono Industrial de Granadilla is a wastewater treatment plant located in Arico, on the island of Tenerife in the Canary Islands, Spain. The plant serves a population of 2,931 and has a designed capacity of 10,000 m³/day, currently discharging 531.24 m³/day. It provides primary treatment, which involves physical processes like sedimentation to remove solids. As a Spanish plant, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent (PE) between 2,000 and 10,000, the directive requires secondary treatment as a minimum. The plant's coastal location subjects it to additional scrutiny under EU directives for sensitive areas. The treated effluent is discharged into the Atlantic Ocean near the southeastern coast of Tenerife. The Canary Islands are a biodiversity hotspot, and coastal discharges can affect marine ecosystems, including seagrass meadows and coral communities. The plant's proximity to the coast (within 10 km) underscores the importance of adequate treatment to protect the marine environment.
Environmental context
The plant discharges into the Atlantic Ocean off the southeastern coast of Tenerife, part of the Canary Islands archipelago. This region is ecologically sensitive, supporting diverse marine life including cetaceans, sea turtles, and endemic fish species. The coastal waters are influenced by the Canary Current, which transports nutrients and larvae, making the area important for regional biodiversity. Discharges from the plant may impact local water quality and marine habitats, particularly if treatment is insufficient.
