The Singapore River was a typically and sadly abused river, a dumping ground from the time people settled along its banks. The growth of modern Singapore amplified that pollution to such an extent that the river was pitch black in many parts. My ecology class always hears about this during the aquatic biomes lecture when I talk about nutrition states of water bodies because the memory of the filthy state of the river still haunts me!
Well-embedded in my mind in particular is the condition of the Kallang River which flowed past St. Andrew’s School – it was a black river and during postwar years, regularly flooded the farming areas of Potong Pasir upriver. Residents sought refuge with the school on Woodsville Hill and this is remembered well in the school’s history alongside other efforts to help our neighbours, to the schoolboys who came later.
Jerome Lim recalls the flood in The Long and Winding Road:
“Potong Pasir would usually be one of the worst hit areas and I remember being able to see only the attap and zinc roofs of houses from the vantage of the block of flats I lived in in Toa Payoh, which overlooked the area. Vegetable farms were destroyed and much of the livestock kept in the pig and poultry farms would have drowned – another thing I remember seeing is the clean pink carcasses of pigs floating in the flood waters.”
Kallang River is the longest river in Singapore, but spans a mere 10km. It begins from Lower Peirce Reservoir and runs through the boundary of Ang Mo Kio and Bishan, and cuts through Braddell, Toa Payoh and Potong Pasir before passing St. Andrew’s at Woodsville. The Bukit Timah Second Diversion Canal joins it and then tributaries join it from in the Balestier/Serangoon/Whampoa areas (Sungei Whampoa), the MacPherson/ Aljunied/Geylang areas (Pelton Canal), the Serangoon (Little India)/Rochor/Jalan Besar areas (Rochor Canal/River) and the Sims/Geylang/Mounbatten areas (Geylang River).
The confluence drains into the Kallang Basin, northeast of the Singapore River – explore OneMap for the complete system and for a trace of the main Kallang River, see this map:
In Tim Light’s recollection of his days in St. Andrew’s School, he remarks,
“My recollection of the school in 1961 is that it was a large building set in a semi-rural location. The playing fields were extensive, and the Kallang river formed one boundary. We were warned to stay away of the river, on account of the aggressive crocodiles, which had been known to attack humans. I never went near the river.”
Heritage blogger and author, Lam Chun See who hosts Tim’s articles, provides the important clarification:
“Your teachers did right to warn you to keep clear of the Kallang River. If you had fallen in, you were unlikely to be attacked by crocodiles. More likely you would be overwhelmed by the stench of dead chickens, pigs and other animals. … We kampong folks [upriver] used to call the Kallang River, “Dead Chicken River“? “
Earlier in his blog, Chun See had written,
“Many of the village folks (not our family, I must declare) used to discard dead animals like chickens, dogs and even pigs into the river. The resulting stench was sometimes so strong that whenever we walked or cycled past the river, we had to hold our breaths. Sometimes, when the tide was low, you could even see the maggots crawling all over the carcasses, a sight that even we kampong kids found it difficult to stomach.

I could easily been one of those boys!
In the 70’s when I was in the primary school, things had not improved. Retrieving a precious football which had gone astray from the school field into the river was a descent into hell and would mark you, well, for the rest of the day! The smell was glorious of course, as there was plenty of hydrogen sulphide emerging from anoxic processes in the mud.
It was a much shallower river then as it was well silted up.
We did not have a swimming pool in the school then, but we were proud of our stinky river and I missed it when we went away to SAJC in 1983-4, which was then in Malan Road along the Southern Ridges.
Well, that is all thankfully a distant memory and the waters of the basin are in a much better state now. In 2006, the primary and secondary schools of St. Andrew’s were reunited with the junior college and connected to it by our very own bridge across the Kallang River.
When I helped my buddy Yew Chee Chien manage operations during the St. Andrew’s Carnival (part of the school’s 150th Anniversary celebrations) in April this year, I stood on the bridge during the safety recce to contemplate the healthier condition of the river.
And wished it could be just as so all over Southeast Asia.
That the river was clean was no result of popular wisdom. It took a massive, dedicated and integrated effort spanning a decade, from the challenge issued by PM Lee Kuan Yew in 1977 to the time sandy beaches were created on Kallang Basin.
By 1984, the river was clean enough for a mass swim to be organised across the river. It included the artist and Parliamentary Secretary for Education, Ho Kah Leong. Despite a dead dog being fished out moments before the swim, the event was a success and marked the transformation of the river. Certainly the 400 who swam the river have boasting rights!
Everyone living in Singapore should have some familiarity with the transformation of the river and an easy way to get acquainted with the scale of operations is to flip through this colourful presentation from PUB (2004), just click to view or download:
“The Cleaning Up of Singapore River and Kallang Basin (1977 – 1987).”
Drainage Department,
PUB; Jan 2004.
The phenomenal changes incurred a social cost, which is discussed in Stephen Dobbs’ (2003), “The Singapore River: A Social History, 1819-2002.” 220p. Available from NUS Press.
The least we can do now is to keep our rivers clean. As land and water is connected, this means keeping our ground litter-free too. A fairly straight-forward principle, one might think.
Left to our own devices though, would we keep our rivers from turning black again?
