It was a sleepy, you know, Bedouin town half a century ago. And what you do is when you bring in the world&rsquo;s, you know, most sophisticated architects and engineers, you can literally build anything, including a building of 140 or 150 stories. But designing a municipal network of sewage treatment is in some ways more complex. - KATE ASCHER</p></em><br /><br /><p> Terry Gross recently interviewed Kate Ascher about her skyscraper book, and ended up discussing the common lack of sewage connections in Dubai - including the Burj Khalifa. So they end up using trucks to cart the sewage to the central treatment plant, where they often end up queuing for 24-hours or more before they can be emptied.</p> <p> <a href="http://us.gizmodo.com/5857475/without-trucks-the-tallest-building-in-the-world-would-become-the-tallest-mountain-of-poop" rel="nofollow" target="_blank">Gizmodo </a>calculated:</p> <p> '<em>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.</em></p> <p> <em>That's a lot of poop.'</em></p>
