We think before we offer
At ACTIVA INGENIEROS, S.L.we believe that every drop counts.
For this reason, before designing a water treatment system, we analyse and define the most appropriate process adapted to the conditions of the raw water, the requirements in the quality of the treated water, the requirements of the client and the real physical and regulatory limits of the project.
We do not work with catalogs. We work with you.

Our Story
Activa Ingenieros SL is a company founded in 2004 created by Industrial Engineers from various engineering firms, consultancies and process integration companies, where the accumulated experience extends well beyond its year of incorporation.
The specialties developed were initially based on engineering services of all kinds of technical disciplines, highlighting those related to water treatment. Subsequently, Activa Ingenieros S.L. acquired the entire technological package of Tecexsa, a pioneering company in water engineering since the 70s, which has significantly increased the potential of our company, offering proven, guaranteed technological solutions of high technical quality.
Our heritage
Our heritage comes, first of all, from the experience accumulated by its senior Master of Engineerings who make up the main core of the staff of Activa Ingenieros S.L., experience that significantly exceeds 30 years of dedication.
Secondly, from Tecexsa’s experience and references at national and global level, since its foundation in the 70s.
As a final result, we provide a deep knowledge of all the treatment processes in the world of water, a professional ethic inherited from years of committed work and the ultimate respect for the environment.
Today, that legacy lives on in each of our projects: More precise designs, with measurable results and a real commitment to sustainability.
A sustainable future is designed from technique
Every project we develop contributes to a more efficient and sustainable future.
Because water is much more than a resource: it is a shared responsibility.
