ETAR de Acorán - Primary Wastewater Treatment Plant in Santa Cruz de Tenerife, Canary Islands

ETAR de Acorán is a wastewater treatment plant located in the Acorán district of Santa Cruz de Tenerife, on the island of Tenerife in the Canary Islands, Spain. The plant serves a population of approximately 4,400 residents and has a designed capacity of 10,000 cubic meters per day, with an average discharge volume of about 798 cubic meters per day. The plant provides primary treatment, which involves physical processes such as sedimentation to remove solids. As a facility in the European Union, it is subject to the Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges to coastal waters unless a less sensitive area designation applies. Given its coastal location, the plant's treatment level may be evaluated under these regulations to minimize marine impact. The treated effluent is discharged into the Atlantic Ocean near the southeastern coast of Tenerife. The surrounding marine environment supports diverse ecosystems, including seagrass meadows and rocky reefs, which are sensitive to nutrient inputs. The plant plays a key role in protecting coastal water quality in this ecologically important region.

The plant discharges into the Atlantic Ocean off the southeastern coast of Tenerife, part of the Canary Islands archipelago. This coastal area supports sensitive marine habitats, including seagrass beds and coral-like formations, which are vulnerable to nutrient enrichment from wastewater. The discharge contributes to the overall health of the coastal zone, which is important for local fisheries and tourism.
