Overview
TIAS wastewater treatment plant serves the municipality of Tías in Lanzarote, Canary Islands, Spain. It treats wastewater from approximately 33,000 residents in the Puerto del Carmen area.
TIAS is a wastewater treatment plant located in Tías, on the island of Lanzarote in the Canary Islands, Spain. It serves a population of around 33,000 people, primarily from the tourist hub of Puerto del Carmen. The plant is situated near the coast and plays a key role in protecting the island's marine environment. As a Spanish facility, TIAS operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (33,000 population equivalent), the directive requires secondary treatment as a minimum, with more stringent treatment if the discharge is into sensitive areas. The plant's designed capacity is 1.00 cubic hectometer per year, indicating a moderate scale facility. The treated effluent is discharged into the Atlantic Ocean, as the plant is within 50 km of the coast. Lanzarote's volcanic terrain and limited freshwater resources make wastewater treatment critical for preventing nutrient pollution in coastal waters, which could harm the island's unique marine ecosystems and coral reefs. The plant supports the local tourism economy by maintaining water quality in nearby beaches and recreational areas.
Environmental context
The TIAS plant discharges treated wastewater into the Atlantic Ocean near the southeastern coast of Lanzarote. The receiving waters are part of the Macaronesian marine ecoregion, which hosts diverse species including sea turtles and cetaceans. Nutrient loading from wastewater could contribute to eutrophication in coastal areas, potentially affecting seagrass meadows and algal communities that are vital for local fisheries and biodiversity.
Frequently asked questions
The TIAS plant is located in Tías, on the island of Lanzarote in the Canary Islands, Spain. It serves the Puerto del Carmen area, a major tourist destination.
The plant serves approximately 33,000 people, with seasonal fluctuations due to tourism in Puerto del Carmen.
The treated effluent is discharged into the Atlantic Ocean, as the plant is located within 50 km of the coast. The discharge point is likely offshore to ensure dilution and minimize environmental impact.
As a Spanish facility, TIAS operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 10,000 population equivalent. The Canary Islands may have additional regional regulations for coastal protection.
Under the EU directive, plants serving over 10,000 people must provide at least secondary treatment. In coastal areas like the Canary Islands, tertiary treatment may be required to protect sensitive marine environments from nutrient pollution.
