HARIA Wastewater Treatment Plant, Teguise, Lanzarote, Canary Islands

HARIA is a wastewater treatment plant located in Caleta de Famara, Teguise, on the island of Lanzarote in the Canary Islands, Spain. It serves a population of approximately 4,000 people, reflecting its role in a small coastal community. The plant is situated near the Atlantic Ocean, within 10 km of the coast, and operates under Spain's implementation of the EU Urban Waste Water Treatment Directive. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for sensitive areas. With a designed capacity of 2,250 m³/day and a current discharge volume of 157.08 m³/day, the facility has ample capacity to handle peak flows. The advanced treatment level ensures high-quality effluent suitable for discharge into the sensitive coastal environment. The treated wastewater is discharged into the Atlantic Ocean, contributing to the protection of the surrounding marine ecosystem. The Canary Islands are known for their unique biodiversity, and the plant's advanced treatment helps safeguard coastal waters and beaches, which are vital for tourism and local marine life.

The plant discharges into the Atlantic Ocean near the coast of Lanzarote, part of the Canary Islands archipelago. The receiving waters support diverse marine habitats, including seagrass meadows and rocky reefs, which are important for fish and invertebrate species. The advanced treatment minimizes nutrient loading, helping to prevent eutrophication in these oligotrophic waters.
