Look across the water at Kallang Riverside and you will see a fascinating mix of Singapore in one frame: red-roofed condominiums, the sweeping roof of the National Stadium, bridges stretching across the river and skyscrapers rising in the distance.
It may feel calm today, but the Kallang River has witnessed plenty of action.
Flowing from the central part of Singapore towards Kallang Basin and Marina Reservoir, it is the country’s longest river. Long before waterfront promenades and cycling paths appeared, the river supported fishermen, boatmen and riverside communities. Boats transported people and goods through the area, while factories, workshops and the former Kallang Gasworks later turned the district into a busy industrial zone.
As Singapore developed, the river’s role began to change. Polluted waterways were cleaned up, ageing industrial areas were transformed and the riverbanks gradually became recreational spaces where people could jog, cycle, kayak or simply enjoy the view.
But this is not just a pretty river.
Rainwater from the surrounding catchment flows through the Kallang River and eventually enters Marina Reservoir. Marina Barrage, built across the Marina Channel, keeps seawater out and allows the reservoir to collect freshwater. After treatment, this water contributes to Singapore’s drinking-water supply.
The barrage also works as a giant flood-control system. During heavy rain, excess water can be released into the sea when tides are low. When tides are high, powerful pumps help move the water out instead. It is a clever combination of water supply, flood protection and recreation—all packed into one engineering project.
Kallang is also deeply connected to Singapore’s sporting memories. The former National Stadium was home to the famous “Kallang Roar”, when football supporters filled the stands with deafening cheers. Today, the Singapore Sports Hub continues that legacy with the National Stadium, Indoor Stadium, Kallang Wave Mall and waterfront sporting facilities.
More changes are coming. Areas around Kallang, Tanjong Rhu and Kampong Bugis are expected to welcome new homes, greener public spaces and improved walking and cycling connections. Future residents could find themselves living beside the river, close to sports venues and only minutes from the city centre.
Kallang Riverside is therefore more than a scenic photo stop. It is a place where old industries, sporting memories, water security and Singapore’s future neighbourhoods all flow together.
