Wanderlust World Wanderlust World By the 1970s, the Singapore River had become severely polluted due to rapid, unregulated urbanization and industrialization. The main culprits:
Textile, tannery, and rubber factories dumped untreated chemical waste—heavy metals, dyes, solvents—directly into the river.
Inadequate sanitation infrastructure meant domestic wastewater flowed straight into the waterway, spiking biological oxygen demand and killing aquatic life.
As a growing port, the river saw constant marine traffic. Oil, fuel, and ship waste further degraded water quality.
Fertilizers and pesticides from nearby farms washed in, causing eutrophication and algal blooms.
Lax enforcement and limited environmental consciousness allowed pollution to continue unchecked.
Starting in the late 1970s, a massive, multi-decade cleanup transformed the river. Today, it's a centerpiece of Singapore's urban landscape—clean, vibrant, and teeming with life.
