During the scorching summer of 1858, the capital of the British Empire was completely paralyzed by an invisible yet suffocating enemy: fecal decomposition. Historically known as The Great Stink (The Great Stink), this event permanently transformed urban planning and global public health.
In the mid-19th century, the rapid adoption of the modern flush toilet discharged the waste of more than two million people directly into the River Thames, which also supplied drinking water to the city. An unprecedented heatwave in July and August literally cooked the accumulated sewage sludge on the riverbanks. The resulting stench was so unbearable that Members of Parliament could not hold sessions; in a desperate attempt, they soaked the curtains of the House with chloride of lime and even considered evacuating the government to Oxford.
The collective terror of epidemics sparked a historic reaction:
- Express approval: Parliament drafted and passed a bill in just eighteen days, granting full powers and substantial funds to transform the capital's underground.
- Bazalgette's feat: Civil engineer Joseph Bazalgette designed a monumental gravity-based system with more than 1,800 kilometers of street sewers and 132 kilometers of main intercepting channels.
- Masterstroke against cholera: Although the medical establishment believed diseases spread through 'miasmas' or foul air, the massive removal of fecal bacteria from the water eradicated devastating cholera epidemics in the metropolis.
That pestilential summer forced London to bury its own filth beneath hundreds of millions of bricks, creating the underground sanitary infrastructure that still operates today.
