Let’s do the math here. The Burj Khalifa has 163 habitable floors. It’s designed to hold 35,000 people at any given time. Now, humans produce 100 to 250 grams (3 to 8 ounces) of feces per day. Let’s say 200 in this case, since these people are well fed. That’s 7,000,000 grams per day. Seven tonnes of poop per day. Now, add human-produced liquids (pee, bathing, cleaning their teeth…) and the water to push the poop down its miles of sewage pipes. I think a very conservative total would be 15 tonnes of sewage per day.

That’s a lot of poop.

And all of it has to be removed by trucks. The trucks take all this poop to a sewage treatement facility outside of the city. It’s the same with most skyscrapers in Dubai, according to Kate Ascher, author of The Heights. Talking to Fresh Air’s Terry Gross, Kate said that these trucks are in a permanent line waiting to get into the sewage treatment plant, waiting up to 24 hours before they can unload their crap.
