Looked up how much water a single fire hydrant pumps and it broke my brain
I was helping my kid with a science project on city water systems and stumbled onto the flow rate for a standard fire hydrant. Turns out a typical one can push 1,500 gallons per minute at full pressure. That's like filling a whole swimming pool in under 10 minutes. I always figured they were strong but didn't realize the math was that crazy. My kid's project got an A and now I can't look at a hydrant the same. Have any of you run into a random stat that just stuck with you?

Hang on, I gotta push back on this. 1,500 gallons a minute sounds insane but those numbers are usually for brand new systems running at max. In real life, most hydrants are barely hitting half that because of old pipes, sediment, and the city not maintaining them. Plus, think about it - if every hydrant actually dumped 1,500 GPM, you'd have streets flooding and water main ruptures left and right. It's more like a marketing figure than a real world stat. Did you check the actual pressure in your own neighborhood?

Haha yeah that's fair. I actually checked mine after a similar deep dive and the flow was way lower than the big number online. Still impressive but not quite swimming pool in 10 minutes level lol.
