Vienna, Austria, September 17th+18th 2025
Since 1999, the biennial International Swimming Pond Convention has been a source of inspiration for new ideas and innovation, as well as a hub for interdisciplinary exchange of specialist companies and manufacturers who plan, build, supply, operate and assess natural bathing waters.
The expertise will be passed on to the participants by outstanding speakers at this Convention.
The 13th International Swimming Pond Convention will take place on 17th and 18th September 2025 in Vienna, Austria. The proven concept of the 10th Convention in Warsaw is largely taken over.
Venue is the Eventhotel Pyramide, Vienna, Vösendorf, a modern 4* business hotel with outstanding travelers rating. Lecture rooms, workshops, exhibition in the foyer, rooms and restaurant are in the immediate vicinity and within the resort.
