The summer of 1956 clearly showed that, in addition to enthusiasm and a strong desire to compete, the development of quality water polo teams largely depended on available conditions — primarily swimming pools or suitable still waters, which some towns such as Kikinda, Zrenjanin, Bela Crkva, Bečej, Subotica, and Senta already had.

In the summer of 1957, a “half-pool” floating platform was once again installed on the Tisa River near Gradište, enabling the continuation of organized training sessions and competitive activities.

Under the influence of leading Vojvodina swimming clubs such as Proleter Zrenjanin, Spartak Subotica, Radnički Kikinda and others, new competition rules were introduced within the Zrenjanin Swimming Subassociation. In addition to swimming and water polo events, compulsory diving was added, performed from a 4-meter platform and a 2–3 meter springboard.

After two relatively successful seasons and the formation of a solid water polo team, the club concluded that the training and match conditions on the Tisa River—flowing, open water—were too poor. It was believed that under such conditions the team would not be able to compete with clubs training in swimming pools or other “still” waters (lakes, canals, sluice areas, or the Danube backwaters). A new solution had to be found.

The audience that attended swimming and water polo competitions when they were held on the Tisa River was mostly from the central part of the town and the riverside area, that is, from Novi Bečej itself. For the residents of Vranjevo, however, this location was quite distant, as they usually swam “by the town” and around the island.

The development of water polo in Vojvodina resulted in seven clubs from Vojvodina and one from Belgrade competing in the Republic League of Serbia. The season began with elimination tournaments held in Bečej and Bela Crkva, after which the First and Second Republic Leagues were formed based on the results achieved.

With great ambitions and the strongest squad in its history up to that point, PVK Jedinstvo entered the 1962 competitive season. Most of the players were in their prime sporting years, between 19 and 22 years old, while valuable experience was provided by Sava Ivanić (29) and Petar Fa (25).

The departure of player-coach Sava Ivanić, along with Živorad Berbakov and Petar Fa, combined with the retirement of Milorad Berbakov and Vladimir Davidović from water polo during the previous two years, dealt a severe blow to Jedinstvo’s water polo team. As a result, players aged only 22 and 23 suddenly became the oldest and most experienced members of the squad, with Zlatoje Marić and Milorad Kiselički taking on leading roles.
