The European Company of Water Treatment was born from the will of diversification of the company MORALES created in 1977. It is specialized in the traditional boilermaking, the piping, the oil works and the water treatment. Since 1990, E.T.E. also equips and installs pools and technical rooms for collective pools. In 1995, the company created an R & D department bringing together engineers and technicians specializing in water treatment. Thus, 7 process patents developed by E.T.E were filed (Activ'H2O ...) as well as several SOLEAU envelopes. In addition to traditional projects such as loading stations for tanker trucks or fire networks, the company has studied and realized for its oil and gas customers, specific installations for the treatment and recycling of industrial water or runoff. In addition, the many achievements in the field of collective swimming pools have allowed E.T.E. to set up, a new structure capable of innovating technologically from data acquired in the field. E.T.E ensures its presence on all continents except Oceania, through its 3 subsidiaries and its distributors. Several markets have been won abroad, particularly in the Maghreb in the field of recycling and waste recovery. Numerous trips abroad have made society aware of the importance of poor quality water resources available to some populations. Following this observation, two years of research and development have enabled ETE to put on the foreign market several ranges of mobile water purification units in several developing countries (Senegal, Morocco, Mexico, Colombia, Kazahkstan ...). The company E.T.E is in collaboration with the universities of Perpignan, Montpellier, Toulouse and La Rochelle as well as with the research organizations CIRAD and CNRS.
