Overview
EDAR Costa del Silencio is a wastewater treatment plant serving 14,640 people in Arona, Tenerife, Canary Islands, Spain. It operates under EU regulations for coastal communities.
EDAR Costa del Silencio is a municipal wastewater treatment plant located in Arona, on the island of Tenerife in the Canary Islands, Spain. It serves a population of approximately 14,640 residents in the Costa del Silencio area, a coastal community known for tourism and residential development. The plant is part of the regional water infrastructure managed by the Canary Islands government. The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size (10,000-150,000 population equivalent) discharging into coastal waters. The designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit), indicating a facility scaled to handle local wastewater flows. The plant's treated effluent is discharged into the Atlantic Ocean near the southern coast of Tenerife. This coastal discharge is subject to stringent EU standards to protect marine ecosystems, including bathing waters and sensitive habitats. The Canary Islands' volcanic terrain and limited freshwater resources make wastewater treatment crucial for both environmental protection and water reuse potential.
Environmental context
The plant discharges into the Atlantic Ocean off the southern coast of Tenerife, part of the Canary Islands archipelago. This region features volcanic coastlines and marine ecosystems that support diverse aquatic life, including sea turtles and cetaceans. The discharge area is within a semi-arid climate zone where water resources are scarce, making treatment quality critical for preserving coastal water quality and tourism-dependent economies.
