Aquifer participates in the Dutch Student Swimming Competition (NSZK), which means that we swim in four competitions a year, each in a different city across The Netherlands. During these competitions, we compete with 11 other student swimming associations for the first place in the overall NSZK ranking. After the competition, there is always a themed party at which we try to get to the first place of the integration bingo ranking!

Once a year the Dutch Championship of Student Swimming (ONKS) is organized. Every year, this grand event takes place in a different student city. In order to let loose a little bit, a party is organized after this competition as well.

In addition to these regular competitions, there is opportunity to participate in an open water competition.
