Intelligence, technology, skills
in perfect harmony.
Sostelia is the leading private Italian player in industrial and civil water treatment technologies. We work to safeguard the precious resource that is water, recovering it and putting it back into the production cycle, so as to tangibly contribute to the goals of a circular economy.
The Group is made up of eight companies with decades of experience in the sector who are active in the supply of water treatment plants, special waste disposal and environmental decontamination.
Each plant offered by the companies in the Sostelia Group is designed to recover water through innovative technologies that allow for the reuse of the resource in its entire cycle, or for the discharge of wastewater in full compliance with current regulations.
Each intervention is tailored to the specific scope of application and takes the technicalities and needs of each customer into account. We apply the most suitable technologies to ensure system efficiency, optimise operating costs and reduce water waste.
There is research, innovation and expertise in everything we do. We employ state-of-the-art technology and effective tools to deliver high-performance facilities.
We design and build advanced industrial and civil water treatment plants, carry out environmental remediation, and work to return a resource of primary importance to its natural destination.
Sostelia brings the technical capabilities of all its companies together. The experience of each company strengthens and enhances the work and expertise of the Group as a whole, making it a unified, versatile and reliable point of reference.
We offer a wide range of tailor-made services at Sostelia, each tailored to the needs of the customer and the application context.
