The five-day tournament would commence from October 28, officials said.
"The event would be organised jointly by Swimming Federation of India (SFI) and Gujarat State Aquatic Association and hosted jointly by Rajkot Municipal Corporation (RMC) and Rajkot District Swimming Association (RDSA)," RMC commissioner Vijay Nehra said.
"The tournament will begin from October 28 and all the necessary preparations have been made. It will be held at Sardar Vallabhbhai Patel Swimming pool at Kothariya road here," he said.
The last time such tournament was held in Gujarat was in 1986, Nehra added.
"The event is important for swimmers who are willing to be part of Indian swimming team for the Summer Olympic to be held in Brazil next year," he added.
