Built only a year earlier, the venue is hosting the Southeast Asian Games for the first time. It was used to host the second Southeast Asian Swimming Championships in 2014 as a test bed for the organisers, with the 2015 Southeast Asian Games volunteers roped in to also volunteer in the 2014 Swimming Championships to help in the familiarisation of the new venue. This Aquatics discipline featured 38 long course events: 19 for males and 19 for females. This restores six events which were dropped by the previous host, Myanmar in the 2013 edition. With swimming being a traditional gold mine for Singapore, there were high expectations for the squad to deliver another record haul of medals, especially given that Singapore is the host country. Two male athletes in particular, namely Joseph Schooling and Quah Zheng Wen were expected to shoulder the responsibility for the hosts, being entered in nine and 12 events respectively. Other athletes expected to shine include Quah Ting Wen, Tao Li and Danny Yeo. Indonesia, Thailand and Vietnam were expecting to present the most resistance to Singapore's ambitions. Training in the United States, Nguyễn Thị Ánh Viên from Vietnam will potentially contest to become the most bemedalled athlete with 12 events to be contested.
