Mapping Emergency Drinking Water Hydrants
Did you know that San Francisco has 67 fire hydrants that are designed for emergency drinking water in case of an earthquake-scale disaster? Neither did I. That’s because just about no one knows about these hydrants.
While scouring the web for Cistern locations — as part my Water Works Project*, which will map out the San Francisco water infrastructure and data-visualize the physical pipes and structures that keep the H2O moving in our city — I found this list.
I became curious.
I couldn’t find a map of these hydrants *anywhere* — except for an odd Foursquare map that linked to a defunct website.
I decided to map them myself, which was not terribly difficult to do.
The map, will get better, but at least this will show you where the nearest emergency drinking hydrant is to your home.
Apparently, these emergency hydrants were developed in 2006 as part of a 1 million dollar program. These hydrants are tied to some of the most reliable drinking water mains.
Yesterday, I paid a visit to three hydrants in my neighborhood. They’re supposed to be marked with blue drops, but only 1 out of the 3 were properly marked.
Hydrant #46: 16th and Bryant, no blue drop
Hydrant #53, Precita & Folsom, has a blue drop
Hydrant #51, 23rd & Treat, no blue drop, with decorative sticker
Editors note: I had previously talked about buying a fire hydrant wrench for a “just in case” scenario*. I’ve retracted this suggestion (by editing this blog entry).
I apologize for this suggestion: No, none of us should be opening hydrants, of course. And I’m not going to actually buy a hydrant wrench. Neither should you, unless you are SFFD, SFWD or otherwise authorized.
Oh yes, and I’m not the first to wonder about these hydrants. Check out this video from a few years ago.
* For the record, I never said that would ever open a fire hydrant, just that I was planning to by a fire hydrant wrench. One possible scenario is that I would hand my fire hydrant wrench to a qualified and authorized municipal employee, in case they were in need.
