1st Water & Energy Symposium at the VTA Research Campus



We are delighted to invite you to the 1st Water & Energy Symposium at the VTA Research Campus, which will take place on 16 and 17 October 2024.

This year we are celebrating a very special premiere:

the opening of the VTA Research Campus & Congress Centre in Rottenbach!

On 15 July 2024, a construction meeting was held at which we were informed that, contrary to previous expectations, the VTA Research Campus can be completed earlier than planned. The construction work should be completed by mid-September 2024, meaning that the grand opening ceremony for our prestigious project will take place in mid-October 2024.

Instead of Kitzbühel as usual, we cordially invite you to join us at our new, state-of-the-art location in Rottenbach.

This exciting change also marks the beginning of a new era as we evolve the 12th Water & Energy Symposium into a new format, replacing the 1. Water & Energy Symposium at the VTA Research Campus & Congress Centre.

The VTA Institute for Health and Environment is looking forward to welcoming you to Rottenbach. Join us for exciting presentations, innovative technologies and an inspiring atmosphere as we shape the future of water and energy together.
