The sun burned relentlessly, and while the crowds crowded to get into the water, the Ebertplatz remained completely left on the other side. Only a few children ventured into the fountain, and the catering businesses such as "Kölsches Boor" and the nearby ice cream parlors could hardly see any customers.

It also turned out that even a nearby water playground remained ice cold in the shadow of the high temperatures - unused and punished by the glowing sun.

sustainability and climate protection in the swimming pool

The challenge of overcrowding in the swimming pools is contrasting to the changes that are necessary to comply with the climate goals. According to a report by the German Society for Sustainable Development , swimming pools have to contribute more and more to reduce CO₂ emissions.

The operation of such environmentally friendly water experiences requires a good measure of the environment and health. Guests are encouraged to shower thoroughly before they jump into the water to get the biological balance of the natural bath pond. After all, residues such as sunscreen or sweat have to be avoided so as not to burden natural cleaning.
