TENOYA Wastewater Treatment Plant, Las Palmas de Gran Canaria, Canarias, Spain

TENOYA is a wastewater treatment plant located in the coastal area of Costa Ayala, Las Palmas de Gran Canaria, in the Canary Islands, Spain. It serves a population of approximately 7,086 people and is classified as a small agglomeration under Spanish and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into coastal waters. Its designed capacity is 6,800 m³/day, and it currently discharges 878.82 m³/day of treated effluent. As a coastal facility within 10 km of the Atlantic Ocean, the plant must meet stringent standards to protect marine ecosystems. The treated wastewater is discharged into the Atlantic Ocean, which surrounds the island of Gran Canaria. The coastal waters in this region support diverse marine life, including seagrass meadows and fish populations, and are important for local tourism and fisheries. The plant's operation helps maintain water quality in the sensitive coastal environment.

TENOYA discharges treated wastewater into the Atlantic Ocean off the northeastern coast of Gran Canaria. The coastal waters are part of the Canary Current Large Marine Ecosystem, which supports rich biodiversity including sea turtles, cetaceans, and commercially important fish species. The plant's secondary treatment reduces organic pollutants and suspended solids, helping to protect the marine environment from eutrophication and other impacts.
