Twenty years ago, construction workers in the Israeli town of Lod working under a city street came across something extraordinary: A massive mosaic, laid down almost two millennia before. Now, they’ve found another.
America's collective human waste contains millions of dollars worth of energy, water, and even rare and valuable metals like gold and palladium. The question is: How do we extract it?
Though it's been around since the Middle Ages, the sewer system beneath Paris won fame in the 19th century, when the city offered boat tours through the tunnels. This is also when an ingenious method for cleaning clogged tunnels was devised. It involves giant balls of iron and a lot of velocity.
During my tour of LA's sewers, I was consistently amazed by how little I knew about what went on in the drains and pipes beneath my feet. I asked Kent Carlson, the city's sewer and stormwater field operations manager, to stop by and shoot the shit.
"So, do you prefer full-immersion or ankle-deep?" Not quite the reply I'd expected from Kent Carlson, the sewer and stormwater field operations manager for the city of Los Angeles, when I requested a tour of the city's new sewer technology.
Underground in places nobody likes to look, bacteria are doing terrible things to our sewage pipes. The concrete pipes that carry our waste are literally dissolving away, forcing engineers into a messy, expensive battle against tiny microbes.
How old would you say the average piece of NYC subway is? 50 years? 60? You sweet, naive fool. No, the average subway is a nonagenarian. A new report on NYC's infrastructure is out, and it is not good. But should we be panicking?
Andrew Emond, a Montreal-based photographer, amateur geographer, and DIY gonzo spelunker of the city's sewers and lost rivers, has just re-launched his excellent website, Under Montreal. The revamped site now comes complete with a fascinating, interactive map of the city's subterranean streams, documenting Montreal's…
Bad guys can't just close their window shades to hide from the law anymore. A European research group has developed a high-tech way to detect bomb makers and illegal drug labs—by sniffing what they flush down the toilet.
Though we may think we pump out roses when it's go time on the ivory throne, nobody in their right mind would actually want to keep those roses around. So flush them away and down the magical toilet they go! But where do they go? To the vague destination of the sewers. And then where? To the ocean? To the city…
Everybody knows about using oil as a fuel source, but London is putting a new spin on the concept. Soon the city will be mining its own sewers to bring up glorious globs of old cooking grease and melting them down into fuel. Delicious.
A 3,000 gallon surge of raw sewage sucked a Missouri construction worker one mile through a 27-inch wide sewer pipe before he was finally rescued at the 15th hole of a golf course yesterday. He's recovering in the hospital.
