Our History: 100 Years in the Water Sector

In 2026, Fisia Italimpianti celebrates an extraordinary milestone: a century of experience, innovation, and vision in the water management and treatment sector. A history that traces its roots back to 1926, with the founding of Castagnetti Water Treatment, and that has evolved over time through expertise, industrial integration, and a constant pursuit of technological excellence.

From the establishment of Italimpianti in 1957, through the creation of Fisia in 1990, to the merger in 1996 that gave rise to Fisia Italimpianti, the company has built a solid and coherent path, becoming a global benchmark in the design and construction of desalination plants, water treatment systems, and waste management solutions.

Over these 100 years, Fisia Italimpianti has accompanied—and often anticipated—the evolution of technologies. From thermal desalination, which played a leading role in the earliest large-scale industrial projects, to reverse osmosis, now among the most advanced and efficient solutions, the company has consistently positioned itself at the highest levels, contributing to the development and global dissemination of the best available technologies.

A prime example is the Jebel Ali project: when it was completed in 2012, it represented the largest plant in the United Arab Emirates, with a production capacity of 800,000 cubic meters of water per day. An extraordinary infrastructure that significantly contributed to the birth and growth of Dubai—a tangible symbol of Fisia Italimpianti ability to turn challenges into opportunities, bringing water where none existed and enabling the development of entire communities.

Water treatment and desalination are not merely technological solutions: they are essential tools for improving people’s quality of life. They make clean, safe, and accessible water—the most precious resource—available to millions of people, contributing to economic development, public health, and social stability.

The projects carried out by Fisia Italimpianti over the past century represent far more than simple works: they are key milestones in a journey that has seen the company play a leading role in building strategic water infrastructure capable of addressing major global challenges related to resource scarcity and environmental sustainability.

Today, this technical and industrial heritage is not just a legacy, but a concrete driver for the future. The experience gained over a century of activity guides every new challenge, while history provides the solid foundation from which to continue growing, innovating, and creating value.

In a world where water is increasingly central to global balance, Fisia Italimpianti renews its commitment to protecting and safeguarding this essential resource, working every day to ensure its sustainable management and to make it accessible to an ever-growing number of people.
