RO-KA-TECH 2023 - Germany

International Trade fair for Pipe and Sewer Technology

RO-KA-TECH is the trade fair for underground wastewater infrastructure, which opens its doors to trade visitors every two years in Kassel. Pipe and sewer technology companies present their products, innovations and services to network operators, planners and decision-makers from the municipal sector at home and abroad. The trade fair was first held in 1996 under the umbrella of the New Leipzig Trade Fair. 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 the RO-KA-TECH 2017, 286 exhibitors from 19 countries presented themselves on 25,000 square meters of exhibition space. Almost 8000 visitors from 48 countries came to Kassel. The RO-KA-TECH is now the most important national/european trade fair in the field of underground wastewater infrastructure.

World Tunnel Congress 2023 - Greece

The theme of WTC2023 “EXPANDING UNDERGROUND”, will focus on the Knowledge and Passion that our industry offers to Make a Positive Impact on the World. WTC 2023 in Athens, that will be carried out in hybrid mode, will highlight on the multiple advantages and solutions that underground space can provide, at the prospect of a whole new era of smart technology, where sophisticated “digital tools” change investigation, design, construction and operation methods and strategies rapidly.

The congress covers all “hot” topics of the tunnelling and underground space industry, whereas a high scientific level will be ensured as all papers, prior to publication, will be peer reviewed by highly skilled professionals and academics coming from all parts around the world. The total number of the members of the scientific committee exceeds one hundred fifty (150), while all accepted papers for publication will be made available to an open access portal via the platform of a highly esteemed international editor. Hence, the research / work / best practice / efforts of the authors participating in the WTC2023 will be freely and permanently available so anyone, anywhere, can read and build upon his / her / them work.

    Aftes International Congress 2023 - France

    Last year’s event in September 2021, which was highly anticipated after being postponed, was a great success and many of you attended, as both delegates and exhibitors. Despite the public health situation, we welcomed over 3,000 participants. We hope to see at least as many of you again in 2023.

    The central theme of next year’s event is “Underground space at the heart of transitions”

    Whether it is the low-carbon transition, the digital transition, resilience in the face of climate change or new technologies for deploying innovative and adapted solutions, our Association hopes that this congress will show that underground space has an important role to play in these changes in our society.

      You will find us and our products at the booth of our partner F.I.S. France Injection Service.
      We are looking forward to your visit!
