Wastewater treatment plants

How we treat our water


At Canaragua, we carry out treatment at wastewater treatment plants (WWTP). There, wastewater passes through a series of processes to restore the desired quality characteristics. This allows us to return the water to the environment in better condition, thus completing the water cycle.

The main wastewater treatment plants deal with over 48,600 m3/day.

Canaragua currently has various contracts in the Canary Islands, with over 50 wastewater treatment plants in operation, and maintains the sewer system in towns and municipalities in the archipelago. Below are some of the main wastewater treatment plants operated in the Canary Islands:

Wastewater treatment has one main by-product: sludge. How much is produced and of what quality depends on the volume of water, the characteristics of the water, and the technology used in the treatment plant.

At Canaragua, we work to find innovative solutions to eliminate with the least environmental impact possible the sludge generated in wastewater treatment. We use systems that form part of the circular economy (energy production, fertiliser for agriculture, composting, etc.).

In the same area of innovation and the circular economy, we develop systems so that the waste from treatment plants can be reused.

As an example, we reuse silt from pre-treatment as 'beds' on which pipes in the sewer system network rest.
