More than steel discs that keep us from falling into sewers

Happy Manhole Cover Monday!

What, you aren’t familiar? Let me fill you in.

One of the wonders of social media is it allows like-minded individuals to find each other. While we focus on the extremes — white supremacists and other assorted nut-jobs who try to inflate their significance by banding together — fanatics aren’t the only kind of person who connects through social media.

There are, for instance, folks who not only notice the manhole covers most blithely ignore, but admire them, photograph them and then share those photographs. On Twitter. Every Monday.

“There were two things I was constantly taking pictures of: birds, and random bits of infrastructure,” said Bill Savage, a Northwestern University literature professor. “I was riding my bike north on Halsted and noticed a classic sewer cover, a radial design with a golf ball at the center.”

”A few people, including me and Bill, were interested in the infrastructure of the city around us,” added Robert Loerzel, a freelance journalist. “Little things, like manhole covers. The idea of doing it on a Monday was a random moment that happens on Twitter. I had posted some photos — or maybe Bill — on a Monday, and a cartoonist for the New Yorker coined the phrase.”

”I love manholes,” said that cartoonist, Julia Suits. “Love the iron, the metal, because I was a sculpture major at the University of Iowa, I worked at Beloit Foundry and loved the idea of sand cast objects. I’m really interested in economy of design. I prefer simple ones, old ones, worn down by buggy wheels, feet, traffic. That’s what my eye’s attracted to.”

She remembers Manhole Cover Monday beginning like this.

”Bill Savage posted the first manhole, and I jumped on that and said, ‘Yeah!’ and retweeted it. We kept going, and I said, “Hey, Manhole Cover Monday.”

”A joke by her became a hashtag,” Loerzel said. “Now throughout the week, as I’m walking through the city, I’m keeping an eye out for manhole covers, for a design I haven’t seen before. Not many are new or different. But every once in a while I’ll find something odd and save it up for a Monday. Now other people in other parts of the world are tweeting pictures.”

From Barcelona to Bolivia, Montreal to Mexico. And those are just from one Monday in July.

The “SPQR” on this modern Roman manhole cover — an abbreviation for the Latin “Senātus Populusque Rōmānus, or in English, “The Roman Senate and People” — would be familiar to an ancient Roman.

When I’m overseas, I’m on the lookout. I once made a cab stop, in traffic in Rome, so I could leap out and grab a shot of the manhole cover with “SPQR,” the same abbreviation that legionnaires carried into battle 2,000 years ago. In March, I was standing at the bottom of the world, Ushuaia, Argentina. Looking down, I saw a manhole with “Cloacas” — Spanish for “sewers,” but, as any bird lover knows, also the term for the avian excremental cavity. “This’ll rock Manhole Cover Monday,” I thought, snapping a photo.

”I feel a connection, especially when they’re historical,” said Loerzel. “Some are very old, referring to government units that no longer exist: In Grant Park, there are covers that say ‘SPC’ — South Parks Commission. Back in the days before there was a Chicago Park District.”

Though name-checking a defunct agency does not necessarily mean a manhole cover is old, one of the truckload of fascinating facts I discovered after calling the Neenah Foundry and talking with product manager Rob Stumpf, who was only too happy to discuss the 300,000 manhole covers Neenah sends out into the world each year, in a galaxy of designs and sizes.

“The manhole covers in one town could be different by a half inch from a town 30 miles away,” Stumpf said. “Our catalog grows and grows.”

Neenah has been forging covers since 1872. Unlike its citizens, Chicago manhole covers have become lighter over the years. 

”The city of Chicago used to use a cover that was 320 pounds,” Stumpf said. “As technology got better, foundries realized they could make these lids a lot lighter and a lot stronger.”

A standard Chicago sewer cover weighs 143 pounds and costs about $120. New, it’s a dull steel color that quickly oxidizes. Some new lids still carry markings from defunct city agencies, like “Chicago W.W.,” for Chicago Water Works, which no longer exists. They do so for the simple reason, Stumpf said, that “no one from the city has requested a lettering change.”

Manhole covers are artwork and history below our feet.

”They’re aesthetically, texturally interesting,” Savage said. “They tell you the history of the industrial city, history built into the landscape. I think it’s a good thing to pay attention to the world you live in, and pay attention to details of that world. Cities are impossibly complicated, built environments that accrue over generations and centuries. The past is always there if you look for it, and the more you know about the past, the better you are situated in the the present.

So it’s possible to love manhole covers?

”Oh gosh yes,” Suits said. “They’re very beautiful. I’m curious: who designs them? They were designed with such care. Sometimes with beautiful asymmetry and detailed filigrees. So much variety. I wonder about the folks who designed them, made them, poured the metal.”

Funny you mention that, Julia. Because Rob Stumpf promised me that as soon as Neenah is ready to pour the next batch of Chicago manhole covers, he’ll give me a call so I can hurry up and watch. Something to look forward to.
