Lee Ek Tieng

50 years of failure because everyone was solving the wrong problem. One man solved it in 10 — by refusing to treat the river as an environmental problem.

I grew up thinking Lee Kuan Yew cleaned the Singapore River.

He didn't. And LKY himself would be the first to correct you.

"There would have been no clean and green Singapore without Lee Ek Tieng."

Here's what I didn't know until recently:

The Singapore River was an open sewer for most of the 20th century. LKY described it from his school days at RI in the 1930s as smelling "worse year by year." At low tide, the stench across the city was, his own words, "dreadful."

Governments came and went. Plans were drawn up. Committees formed. Nothing changed.

Then in 1977, LKY made a public bet. Clean the river in exactly 10 years. He promised a solid gold medal — one troy ounce — to every officer involved the day it was done.

Lee Ek Tieng was Permanent Secretary of the Ministry of the Environment.

Here's what he saw that everyone before him had missed.

For decades, the river had been treated as an environmental problem. Water quality. Pollution levels. Treatment infrastructure. Wrong diagnosis.

The river wasn't dirty because of bad water management. It was dirty because of 46,187 squatters living in the catchment area with no sewage facilities. Because of 4,926 hawkers and vegetable vendors dumping waste along the banks daily. Because of 610 pig farms, 500 duck farms, and 2,800 backyard cottage industries — all legitimate livelihoods, all operating for generations, all poisoning the river.

Nobody had wanted to move them.

Lee Ek Tieng moved them.

Over a decade, every squatter family was resettled into HDB public housing. Every hawker relocated to a new food centre. The pig farms were given notice, then phased out entirely by 1982. The bumboats that had worked the river for generations were cleared. The backyard trades moved on.

Then — after every source of pollution was gone — he dredged the entire riverbed one full metre down. Fifty years of accumulated waste, removed. Replaced with clean sand.

The stench that had plagued Singapore since the 1930s disappeared within a week.

Budget estimate: S$30 million. Final cost: S$300 million. Ten times over. Nobody stopped the project.

On 2 September 1987 — exactly ten years to the date — LKY stood at a ceremony at Marina Bay and presented solid gold medals. Fish had returned to the river.

Clarke Quay and Boat Quay would follow.

Lee Ek Tieng's name rarely appears in any account of it.

Not an environmental project. A relocation project. A political project. A decade of convincing, compensating, and resettling tens of thousands of people who had done nothing wrong except build their lives next to a river that Singapore needed back.

The river didn't need better water treatment. It needed someone willing to move what was causing the problem.

50 years of failure because everyone was treating the symptom. 10 years to success because one man went after the cause.

What problem in your work has been 'stuck' for years — because everyone's been treating the water instead of moving what's poisoning it?
