SV Poseidon is currently the largest swimming club in northern Germany with around 1,000 members. The heart of the club is its own outdoor pool at the Olloweg, which is the location for many competitions and leisure activities in the summer.
Even though the first water polo team is the sporting highlight of the club, the SV Poseidon offers all members the opportunity to get involved or take advantage of activities from the various programme.
In addition to the obligatory swimming lessons for children as well as swimming and water polo training, the SV Poseidon members can take advantage of courses offered by Grün-Weiß Eimsbüttel, some of which are free of charge, as part of a cooperation agreement.
