Our History

Our history

TEDAGUA (Técnicas de Desalinización de Aguas, S.A.), was established in 1983 in Las Palmas, Gran Canaria. In its beginnings it performed its business activities within the Canary Islands and the southeast of the peninsula, with sporadic incursions abroad.

Integrated into the Grupo Cobra, it was seen as a benchmark of design, manufacturing, operation, maintenance and engineering for desalination plants, purification systems for drinking and industrial waters, and urban and industrial wastewater treatment and reuse equipment.

The growth experienced by the company these last few years has led TEDAGUA to be considered today as one of the main companies in the water treatment sector in Spain, with contracts across the five continents.

Our Essence

At TEDAGUA we believe that the best way to effectively respond to the evolution of new needs in relation to water treatment and industrial solutions is specialization.

Water, our essence

In this way, we guarantee the highest levels of quality and service across every process, from the research of new solutions and the execution of projects, to post-sales services.

Throughout the last few years, TEDAGUA has carried out its business based on the research & development of new technologies applied to the water sector, and mostly aimed at increasing the performance of each process. Nowadays, processes such as the reuse of water or the desalination of brackish or sea water have gone from being considered complicated, expensive and dubiously reliable water obtainment processes to being more feasible, efficient and reliable.

As a result, we have developed an assortment of product lines that enable us to offer an effective solution to a wide range of issues: from Modular and Compact Plants that are characterized by their nonexistent or minimal construction work requirements, to plants for major population centers such as DWTP and WWTP, which are designed to treat high volumes of water at a minimal cost.

A few examples of this are the large quantity of desalination plants developed for hotel resorts or small-scale agricultural operations in the Canary Islands, the large Escombreras, Spain sea water desalination plants or those of Skikda and Beni-Saf in Algeria, in addition to tertiary water treatment centers such as the WWTP of Altona –near Melbourne, Australia– and the WWTP of Taboada in Lima, Peru – the largest in South America.

How we work

How we act

Each project is developed based on the characteristics of the water to be treated and its final use, offering a solution tailored to the specific needs of the project for each case.

We currently have over 150 desalination plants in operation with a global production capability of over 900,000 m3/day. This implies a significant experience in the water sector, proof of which is the satisfaction of our clients.

Our commitment to service prompts us to export our know-how and technology to practically anywhere in the world, which is in no small part facilitated by the support that being a part of Grupo COBRA since the year 2001 implies.
