History
In 1968 a major breakthrough in piped rainwater drainage systems was made when Olavi Ebeling invented the UV-System™. Mr. Ebeling was soon joined by Dr. Per Sommerhein who, as co-developer, assisted in promoting the system throughout Scandinavia.
Finlandia Hall, Helsinki, Finland
Over the last 35 years Dr. Per Sommerhein has pioneered the technical development of siphonic rainwater systems for the discharge of rainwater from roof areas and has set the construction industry standard around the world.
Since the first major UV-System™ installation, an ABB turbine factory, was completed in 1972, large numbers of prominent buildings have benefited from the UV-System™ technology. The range spans from airports like Stansted International Airport in the UK, Oslo Gardermoen International Airport in Norway, and Guangzhou Baiyun International Airport in China, to office towers like Citibank Group Shanghai, convention centers like Boston Convention and Exhibition Center in the United States, and sport stadia like Reebok Stadium and Nanjing Olympic Stadium.
To this day the UV-System™ remains the leader in siphonic rainwater systems worldwide with its advanced, high quality products, and sophisticated engineering solutions.
