RO-KA-TECh - germany
International trade fair for pipe and sewer technology
RO-KA-TECH is the trade fair for the underground wastewater infrastructure sector, which opens its doors to trade visitors every two years in Kassel. Companies from the pipe and sewer technology sector present their products, innovations and services to network operators, planners and decision-makers from the municipal sector in Germany and abroad.
The trade fair was organized for the first time in 1996 under the umbrella of the New Leipzig Trade Fair Centre. What began as a small industry get-together with 60 exhibitors from 3 countries has developed over the years into an internationally renowned trade fair. At RO-KA-TECH 2023, more than 300 exhibitors from 23 countries presented themselves on over 30,000 square meters of exhibition space. Almost 13,000 visitors from 71 countries came to Kassel to find out more.
RO-KA-TECH is now the most important national/European trade fair in the field of underground wastewater infrastructure.
The location of the venue in the middle of Europe is one of the great advantages of RO-KA-TECH. The focus on technologies and systems relating to pipe and sewer technology has also helped to establish it as a know-how hotspot. The range of services extends from cleaning and inspection to trenchless rehabilitation of wastewater systems. Anyone with responsibility in this area will find everything they need to know in concentrated form in the Kassel exhibition halls.
