Sireg Hydros is a company of the Sireg Group, which was created from the spin-off of the pre-existing "Water Division" in early 2015.

Sireg, founded in 1936 and from its origins specialized in the production of thermoplastic products for geotechnics and for the electric battery sector, in the late 1980s decided, thanks to the foresight of Edoardo Blanc, son of its founder, to further diversify its activities with the design and construction of innovative primary water treatment plants for civil and industrial use.

The long experience gained in the sector, with research and the application of the most modern technologies, has allowed the company, from 1988 to the present, to consolidate its presence in the national and international market, increasing its design and manufacturing capacity with the realization of increasingly complex, standard and tailor-made plants, able to offer the best solutions to each specific need.

The new company Sireg Hydros, also owned by the Blanc family, is composed of the same highly qualified staff as the pre-existing "Water Division."

Sireg Hydros also boasts an important technical partnership with Sireg H3O, a Sireg Group company specializing in the design and manufacture of complex industrial design products, aimed particularly at the nautical sector. Providing Sireg H3O's creative expertises with its vast experience and valuable technical know-how, the Sireg Hydros team offers powerful leverage for each project in research and development, in material and component testing, and at the prototyping stage.

The company has achieved UNI EN ISO 9001:2015 certification (IQNet quality certificates) for the design, production, sales and technical service of water treatment plants. Sireg Hydros is also a UN accredited supplier in economic and social development projects.
