More than 35 years in the service of water utility construction
THERMIN Vízgazdálkodási és Szolgáltató Kft. started as a family business in Győr in 1991 and has remained a 100% Hungarian-owned company, a defining player in the region ever since.
Founded in 1991
Our core activity is the construction of utilities carrying liquids. We place great emphasis on delivering our commissions to a high standard, meeting the challenges and expectations of our time.
Thanks to our reliability and experience we have already worked on numerous significant projects with Hungarian municipalities, state bodies and private organisations. Our team consists of well-qualified, experienced engineers and specialists who regularly take part in further training so that they are always up to date with the latest technologies and methods.
Our activities are carried out under a quality management system compliant with standard MSZ EN ISO 9001:2015, ensuring the effectiveness, continuous improvement and verifiability of our defined work processes.



We are proud that the quality of our work has allowed us to build long-term client relationships over the decades — and we remain open to new business cooperation.
THERMIN Kft. continues to aim at being a defining player on the Hungarian market in civil engineering and water management, and at contributing with our expertise and high-quality services to the country's development and to the improvement of its infrastructure.

We have been working in civil engineering and water utility construction for more than 35 years. In that time we have gained experience in hundreds of projects, hundreds of kilometres of completed utility networks and countless successfully solved technical tasks.
