On the occasion of World Toilet Day on November 19, American billionaire and philanthropist Bill Gates went down a sewer to visit the Sewer Museum in Brussels. A video shared by Mr Gates on Instagram showed him going down a sewer and exploring the hidden history of Brussels’ sewage system. The video also showed him meeting with scientists to understand the intricate workings of the city’s water waste system. Notably, a 200-mile network of sewers and treatment plants process the city’s waste.

 

”I explored the hidden history of Brussels’ sewage system—and the role of wastewater in global health—for this year‘s #WorldToiletDay,” the caption of the video read. A text inlay on the video reads, ”I experienced it all at the Brussels’ underground museum. Documenting the history of the city’s wastewater system. In the 1800’s the sewage got dumped into the city’s Senne River. That led to horrible cholera epidemics. Today, a 200-mile network of sewers and treatment plants process the city’s waste.”
