The competition took place over three days at the Danube Arena, which has been constructed in time for the World Championships.

Szolnoki VSK claimed a 10-5 victory over Jug Dubrovnik at the venue, which can host a crowd of 15,000 spectators.

Following the World Aquatics Championships and the ensuing World Masters Championships some stands will be removed to leave 6,000 seats.

The facility includes two 50-metre pools, as well as diving, children’s and bubble pools.

Thermal energy obtained through the chilling of hot water is used for the heating of the building, as well as keeping an adequate water temperature in the pools and providing hot water in the showers and toilets.

It is claimed the process means one third of the energy needed to heat the venues comes from a renewable energy resource.

Balázs Fürjes, Government Commissioner for major Budapest developments, claimed all Hungarians can be proud of the venue.

“The fact that the Danube Arena was constructed between spring 2015 and spring 2017 shows that unity between Hungarians can do miracles,” said Fürjes, who was chairman of the Budapest 2024 Olympic bid.

“So not only Budapest but entire Hungary can be proud of the Danube Arena, and it is marvelled all around the world that Hungarians could erect a building like this within two years.

“The Danube Arena is for everyone: training centre for the kids, for clubs and the national teams in aquatics and a proud host venue for international sport events and of course a great multiple-pool complex for the public.”

The venue was claimed to have been delivered under the Government’s budget of €159 million (£138 million/$177 million), which included the cost of the construction and surrounding engineering structures.

The budget also included the development of public transportation, a flood control dam, cost of the demountable seating, the drainage channel protection, the re-structuring and dismantling works after the World Championships and safety provisions.

It is claimed the investment is part of the biggest sport infrastructure development program in Hungary for the past 30 years.

FINA executive director Cornel Marculescu claimed the venue was a fine example for officials from Tokyo 2020, who are visiting the city.

The World Championships are scheduled to be held between July 14 to 30.

Budapest withdrew their bid for the 2024 Olympics and Paralympics amid referendum fears.
