The OCBC Aquatic Centre is the primary aquatic venue within the Kallang precinct, positioned on the northern boundary of the 35-hectare site. It holds three pools, all built to the standards set by World Aquatics (formerly FINA), and it accommodates the full range of competitive aquatic disciplines — swimming, water polo, diving, and artistic swimming. Permanent seating covers 3,000 spectators, expandable to 6,000 with the installation of temporary stands for major competitions.
On a day-to-day basis, the facility operates as a public swimming venue under the ActiveSG network. On competition weekends, public access is suspended and the pools are configured for their event roles. The shift between these two operational modes is a practical characteristic of the facility — unlike the National Stadium, which is primarily an event venue, the aquatic centre functions as active community infrastructure for most of the year.
Pool Configuration
Three separate pool structures make up the facility:
Competition pool: 50 metres long, 10 lanes, 3 metres deep. A movable bulkhead divides the pool to allow both short-course (25m) and long-course (50m) configurations, enabling the facility to host championships under both distance standards within the same calendar year without structural modification.
Training pool: 50 metres long, 8 lanes, between 1.35 and 2 metres deep. This pool runs parallel to the competition pool and is used by club and national squad swimmers for training sessions that run independently of any competition schedule. Its shallower depth compared to the competition pool makes it more practical for children's squads and learn-to-swim programmes.
Diving and multi-purpose pool: 25 metres wide, 5 metres deep. The depth is required for safe diving from platforms and springboards. This pool is also used for water polo and artistic swimming events when configured for competition.

Ventilation and Climate Control
The roof of the aquatic centre is designed to allow natural daylight into the pool hall while managing heat accumulation. Louvres and high-level openings facilitate cross-ventilation, supplemented by large industrial fans mounted above the pool deck. The design reflects a deliberate choice to avoid full air conditioning of the pool hall — the energy demand and cost of cooling such a volume of air to a comfortable competitive temperature would be prohibitive — and instead to focus on air movement and shading to maintain acceptable conditions for both athletes and spectators.
For major competitions, temporary cooling measures can be added to seating areas, and the FINA/World Aquatics water temperature standards (26–28°C for swimming, warmer tolerances for diving and water polo) are maintained through the pool heating and filtration systems rather than ambient air cooling.
The 2015 SEA Games and Joseph Schooling
The OCBC Aquatic Centre hosted the aquatics programme for the 28th Southeast Asian Games in 2015, the first major multi-sport event held at the Singapore Sports Hub complex. Joseph Schooling, then 20 years old and competing in his home country for the first time at a SEA Games, set nine Games records during that competition. The Singapore Synchronised Swimming Team won the country's first gold medal in the sport at the same event. Both results remain significant in Singapore's sporting record and are referenced consistently in the venue's own documentation.
Schooling subsequently won the 100m butterfly gold at the 2016 Rio Olympics, a result that brought renewed attention to Singapore's aquatic infrastructure and training environment. The OCBC Aquatic Centre serves as one of the primary training bases for national-level swimmers through the Singapore Swimming Association, which is headquartered at the venue.
International Events Prior to 2025
Between 2014 and 2024, the facility hosted several recurring and one-off international competitions:
- FINA World Junior Swimming Championships
- FINA Diving Grand Prix (multiple editions)
- FINA Swimming World Cup
- Citi Para Swimming World Series Singapore
- Singapore National Age Group Championship (annual)
These events established a track record for the venue's operational team in managing competition-level water quality, timing systems, media facilities, and spectator logistics within the relatively constrained seating configuration. The temporary stand system, which doubles capacity to 6,000, has been deployed at multiple competitions and is now a standard component of the venue's event toolkit.
The 2025 World Aquatics Championships
Singapore's hosting of the World Aquatics Championships from 11 July to 3 August 2025 marks the first time a Southeast Asian country has held the event. The OCBC Aquatic Centre carries the diving and water polo competitions. Swimming and artistic swimming events were moved to a purpose-built temporary venue — the World Aquatics Championships Arena — constructed on Car Park G within the Kallang precinct, as neither the National Stadium nor the Indoor Stadium was deemed suitable for swimming in its standard configuration. Open water swimming and high diving are held at Sentosa.
The event involves over 2,500 elite athletes from more than 200 national federations. Ticket pricing for events at the OCBC Aquatic Centre ranges from SGD 20 for diving sessions to SGD 60 for finals sessions. Official ticketing is through SISTIC, with general sale having opened in April 2025.
"Hosting the World Aquatics Championships required a practical decision about venue fit. The OCBC pools meet the water and depth specifications for diving and water polo without modification. For swimming, the spectator numbers required for a world championship final exceed what the permanent seating here can accommodate."
Public Swimming Access
Outside competition periods, the OCBC Aquatic Centre operates public swimming sessions seven days a week. Pricing is set at ActiveSG rates, with concessions for children, seniors, and full-time national servicemen. Lessons are available through the ActiveSG academy for both children and adults across all levels. The facility also runs structured fitness classes — water aerobics and aqua fitness — that use the training pool lanes.
Booking for public sessions is managed through the ActiveSG app. Competition blackout periods — when public access is suspended for event setup and competition days — are typically published at least two weeks in advance on both the venue's own channels and the ActiveSG platform.
