TEDAGUA - Member of the ACS Group

TEDAGUA, created in the early eighties, belongs to Cobra Group (ACS Group) enterprise dedicated to the design, engineering, operation and maintenance of Desalination plants, Drinking Water Treatment Plants (DWTP) and other purification water systems, Waster Water Treatment Plants (WWTP), and water reusing equipments for urban and industrial spills. We think the best way to offer posible solutions to gain an evolution of water treatment is specialization. This way, we guarantee the highest quality and service levels in all the processes, from the investigation of new solutions to the making of new projects or the after-sell services.

Year Founded:


TEDAGUA (Técnicas de Desalinización de Aguas, S.A.) began operations in 1983 in Las Palmas de Gran Canaria. In the beginning its activities were focussed on the Canary Islands and south-east Spain, with occasional projects also being executed internationally.

The company was taken over by the ACS Group in 2001, and was incorporated into the Cobra Group. Since then, Tedagua has become an international leader in the design, construction, operation, maintenance and engineering of desalination plants, systems for producing drinking water from brackish feedwater, and plants for recycling water from sewerage feedwater. The company is also a leader in the design and construction of plants for treating and reusing urban and industrial waste for electricity generation.

Tedagua's has grown considerably in recent years and, with water treatment contracts in all five continents, it is now justifiably considered a world leader in the water treatment sector.


TEDAGUA believes that specialisation is the best way to provide an effective response to emerging needs in the water treatment and industrial solutions sectors. Specialisation enables us to guarantee the highest standards of quality and service in all our processes - from research into new solutions and project execution, to our after-sales service.

In recent years, TEDAGUA has put an even greater emphasis on research and development of new technologies for the water sector, in order to find new ways to improve performance. A key result of our specialisation and R&D is that we are now clear leaders in the application of new technologies associated with the desalination of seawater and brackish water. What were once considered complex and expensive ways of obtaining treated water, are now efficient, reliable and cost effective processes.

Our strengths in membrane technology for water treatment has meant we have been able to develop a broad range of new product lines that allow us to provide effective solutions for treating a wide variety of feedwater types. From modular and compact plants, characterised by the fact that they require little or practically no civil engineering work, to drinking water plants for large cities and wastewater treatment plants (WWTPs) which are designed to treat high flows with minimum operating costs, TEDAGUA can provide an efficient and reliable solution.

Some good examples of this are the many small desalination plants executed for hotel complexes or small farms in the Canary Islands, the large sea water desalination plants of Escombreras in Spain or Skikda and Beni Saf in Algeria and tertiary treatment plants such as the WWTP in Altona (Melbourne, Australia) or the WWTP in Taboada in Lima (Peru), the largest in South America.


The design of each project is developed depending on the characteristics of the water to be treated and the water's intended purpose. Design is always project-specific.

TEDAGUA now has more than 150 desalination plants operating, with a global production capacity of more than 900,000 m3/day. The company has a real depth of experience and expertise. This experience and expertise is endorsed by our many clients, who are completely satisfied by our performance.

Our commitment to customer service is one reason why we have been so successful in exporting our services to almost every part of the globe. We now have a significant presence on 5 continents. Another reason for our global success is that we have the financial and logistical backing of our parent company, the COBRA Group (which in turn is a subsidiary of the ACS Group). This support is crucial in enabling us to combine the strength necessary to compete effectively for very large projects, with the flexibility and responsiveness characteristic of a smaller enterprise.

TEDAGUA knows that to obtain high levels of customer satisfaction, and for the company itself, it is necessary to have sustainable management systems to guarantee the quality of our processes and end-products, optimise human and material resources, demonstrate our respect for the natural environment, and underline our commitment to the safety and wellbeing of employees.

For these reasons, TEDAGUA has very a well-developed Management System, which includes UNE-EN-9001 Quality Standards accreditation, UNE-EN-14001 Environmental Standards accreditation, and OHSAS-18001 Occupational Risk Prevention Standards accreditation. Our system has been certified by AENOR in each of these areas, and is also audited internally by qualified professionals.
