Kallang Basin: Rivers, Industry, and Memory

In the late 1970s, I moved out of Hill Street near the Singapore River, and settled at Maude Road by the Rochor River. I lived there for five years before moving on to Tampines. Almost without noticing, I have settled in Tampines for more than four decades.

Back then, my final National Service posting was at Beach Road Camp. I used to walk home after work. I often strolled along the Rochor River to admire the unforgettable sunsets. Those quiet walks, framed by water and fading light, calmed me down and planted the earliest layers of my personal connection with the rivers that flow into Kallang Basin.

Kallang roar

I came to learn more about both the Rochor and Kallang Rivers. These two waterways converge at the Kallang Basin before meeting the sea. Long before it became today’s polished sports and recreational precinct, Kallang was already deeply woven into Singapore’s collective memory. I was a regular at the old National Stadium, built in time for the 1973 SEAP Games, and later the site of Malaysia Cup matches, National Day Parades and musical concerts. It was there that the famous “Kallang Roar” was born.

Yet before stadiums and spectacles, Kallang Basin had been a trading post, a site of early industrialisation, and home to Orang Laut communities. Much of this past now survives only in fragments, memory and imagination.

The "old" National Stadium was being demolished in 2010.

 

Early trade and settlement

As early as the 16th and 17th centuries, the Kallang Basin is believed to have functioned as a busy maritime trading port. Traders moved spices, textiles, and other goods through these waters, well before the emergence of modern Singapore. Among them were Bugis merchants who helped establish the island as a key node in Southeast Asia’s regional trade network.

The basin was also home to the Orang Biduanda Kallang, part of the wider Orang Laut community. Their ancestors traced their roots to the Riau–Lingga Archipelago and Bangka Island.

As settlement expanded, the British administration mandated the use of permanent building materials in 1822. Brick kilns, sawmills and boatyards soon appeared along the Kallang and Rochor rivers, marking Singapore’s earliest steps toward industrialisation.

Abundant mudflats and sand in the Kallang estuary supported small-scale brick kilns set up since the 1830s. In later decades, the basin became home to Kallang Gasworks and Kallang Airport.

Another transformation followed in the 1960s and 1970s, when sand excavated from the hills of Toa Payoh was used to reclaim land in the basin. Today, this reshaped landscape is branded as “The Kallang”.

Sar Kong and Mun San Fook Tuck Chee Temple

Many Chinese settlers employed in the brick kilns lived in a kampong known as Sar Kong (沙冈), meaning “sand dune” in Cantonese. The village revolved around the Mun San Fook Tuck Chee Temple (万山福德祠) founded in 1861 and recognised as one of the oldest Cantonese temples in Singapore.

Located at the junction of Lorong 17 Geylang and Sims Drive, the temple was far more than a religious site. For working-class villagers and newly arrived immigrants, it provided shelter and a sense of community during their earliest days in a foreign land.

Shipbuilding along the Kallang River

Kallang was once a major hub for shipbuilding and repair. As early as 1822, Captain William Flint, Singapore’s first master attendant, had established a shipyard at Tanjong Rhu. From the 1880s to the 1950s, flat-bottomed wooden tongkangs and smaller twakows crowded the Kallang River, ferrying raw materials upstream for processing and re-export.

Tongkangs, larger and seaworthy, transported timber from Indonesia and rice from Thailand, Myanmar, and Vietnam. Twakows, smaller and motorised, operated mainly within coastal waters, linking riverside godowns with cargo ships anchored near Telok Ayer Basin. Wooden boatbuilders and repair sheds lined the riverbanks.

The construction of the Merdeka Bridge in the 1950s prevented tongkangs from sailing further upstream, forcing them to relocate to anchorages at the mouth of the Kallang River and around Tanjong Rhu. By the early 1990s, most shipyards, once clustered around Jalan Benaan Kapal and the Geylang River, had either closed or moved to Jurong, leaving behind a maritime legacy largely invisible today.

Lee Rubber Factory

Singapore lacked the land to become a major rubber plantation. Despite that, rubber processing, packing and milling for export were once a vital industry. Lee Rubber Factory sat on the present site of Kallang Distripark at the upper reach of the Kallang Basin.

The factory at Lorong 3 Geylang functioned as a self-contained industrial complex, complete with processing facilities, warehouses, smokehouses, a training centre, research laboratory and workers’ lodging. Its riverside location allowed tongkangs to deliver raw rubber directly to a small jetty, integrating river transport seamlessly into industrial operations.

Kallang Gasworks: Fire City

Established in 1901, the Kallang Gasworks, nicknamed 火城 (Fire City) by the Chinese, supplied gas for industrial, commercial and household use. While it brought undeniable convenience and improved living standards, it also caused fear. Gas explosions and the constant smell of gas were persistent anxieties for residents.

At its peak, the gasworks supplied around 70 per cent of Singapore’s gas needs. Operations ceased in 1998 after Senoko Gasworks assumed full responsibility the year before.

The Kallang Industrial Estate

After Jurong, the Kallang Industrial Estate became Singapore’s second-largest industrial park. Light and medium industries transformed the basin’s landscape. Factories produced garments, electronic components and toys, while multinational corporations such as Texas Instruments and General Electric established operations here.

For many school-leavers in earlier decades, these factories, established under the nationwide industrialisation programme, offered employment, shaping livelihoods and aspirations across generations.

 

Song Lin Saw Mill and a wartime escape

Song Lin Saw Mill (松林火锯厂), established in the early 20th century, relied on the Rochor River to transport timber and finished products in the early years. When I just moved to Maude Road, I visited the mill to purchase plywood for my family’s metal beds. A friendly supervisor showed me around, giving me my first glimpse into sawmill operations.

Song Lin Building was originally the Song Lin Saw Mill.

Years later, I learned from retired architect James Liaw (廖元虎) about his father, Liaw Chin Sing (廖清醒). A barber from Foo Chow, he was deeply involved in fundraising for China’s anti-Japanese war effort and played a key role in the Second Special District Relief Branch, headquartered on Foch Road.

After the fall of Singapore, Liaw was detained by the Japanese at Song Lin on Syed Alwi Road. Three days later, exploiting the military police’s fear of infection, he escaped by supporting a comrade whose festering wounds were swarmed by flies. It is a small human story hidden within a vast and brutal history.

New Singapore Ice Works

Sungei Road was known to the Cantonese and Hakka communities as 淡水河 (fresh water river), while the Hokkien and Teochew called it 结霜桥 (frozen bridge). The latter name was derived from the New Singapore Ice Works, established in the 1930s and renamed in 1958.

Before refrigerators became common, the ice factory played an important role in daily life. Hawkers, wet market fishmongers, fishing boats and restaurants all depended on its ice supply. Ice was insulated with sawdust and covered with rice sacks, a simple yet effective method. Sawdust from the nearby Song Lin was perfectly suited for this purpose, an early example of practical recycling.

The White Crocodile of Kallang River

In Southeast Asian folklore, the white crocodile (buaya putih) symbolises mystery, power and protection. Stories of guardian crocodiles often serve as omens or protectors of sacred waters.

Crocodiles were occasionally sighted in the Kallang River until the mid-1980s. Among the Orang Laut and Chinese communities, tales circulated of a white crocodile guarding the river. The Orang Biduanda Kallang were said to make offerings to it, while some Chinese believed it lived beneath Chwee Kang Beo (水江庙), a rare riverine temple in Singapore. In reality, the temple had no connection to the legend, but the story endures.

Today, as the manicured riverbanks and stadium lights dominate the skyline, it takes effort to imagine tongkangs, brick kilns, sawmills, ice production and other lost scenes. Yet beneath the modern surface, Kallang Basin continues to carry stories of quiet resilience.

Today's Kallang River is a thriving hub for water sports.
