Since 1999, the biennial International Swimming Pond Congress 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 Congress.
The 12th International Swimming Pond Congress will take place on 27th and 28th September 2023 in Mechelen, Belgium. The proven concept of the 10th Congress in Warsaw is largely taken over.
