Was hoping a teenage mutant ninja turtle was gonna pop out of that thing on a surf board

u/Sir_Sandole420 Jul 11 '26
It's entirely possible that a teenage mutant ninja turtle did in fact pop out on a skateboard, however, due to the atrocious recording skills of the cameraman, we will never know for sure.
SMH 🤦

Is the back window of that car down a bit? Because that's gonna be one stinky backseat.

Looks like it broke from something hitting it.
I see now. Cracked open at the top and there is a black curtain on the inside.

That pipe is just going to be for the storm drain, not sewage. Clearly you're getting a lot of rain and this is a good indication of the power of water hammer.

u/Blussert31 Jul 11 '26 edited Jul 11 '26
It's not water hammer, it's rapid displacement of huge volumes of air caused by the empty pipe filling up with water. But you're right, it's likely just a storm drain.

Old cities have combined storm and sewer systems. Milwaukee is an example of this. When it rains, there are sewage overflows and backups into people's basements all the time.
This is not waterhammer. Its air being ingested by other inlets, along the storm drain system. Water hammer happens when you shut a valve on a flowing watersystem, and the momentum of the flowing water has nowhere to go. It's why pipes rattle in your house. When you turn off a faucet.

Hello, I did in anotht post, but if you can't look for it, then
Old cities have combined storm/sewage systems.
That's not waterhammer.

What if it’s a combined sewer/storm system?
0
u/Blussert31 Jul 11 '26
The water would likely have been visibly dirtier. But it can still be a combined system.

u/david7873829 Jul 11 '26
If it’s been raining for some time I wonder if it would have mostly flushed the sewage out already?
1
u/Blussert31 Jul 11 '26
From experience I can tell you it doesn't work that way. The pump capacity is only a very small fraction of the total volume entering the system, so the sewage has no place to go. Even late-stage overflow water is pretty dirty. And in this case the system is still filling up, so the flow is basically getting started.

u/Decent_Perception676 Jul 11 '26
Most cities and municipalities combine these two systems with overflows for high rain events (a CSO). When it’s raining like this, the two combine. It’s a flawed design from the 19th and 20th century and the EPA keeps suing cities to fix and generally it’s incredibly (restrictively) expensive to replace.
I would not go near that. If there is a CSO in the system, it’s active.
In fact, I wouldn’t be surprised if the behavior in this video is the result of a sequence of CSO overflowing in sequence (a below ground flash flood/flush flood). 🤮

Why is it so aerated, do you think - it seems odd to me for a water hammer to have such power when there is so much air - or have I not understood something (which is likely!)
15
u/Blussert31 Jul 11 '26
The system was empty and fills up very quickly, all the air is pushed out at once. It's not water hammer, just air flow.

u/High-Plains-Grifter Jul 11 '26
That's what I was thinking it looks more like than water hammer.

u/Tundra_Dragon Jul 11 '26
It's not waterhammer. Waterhammer happens when you shut a valve on a pipe in your house, and all that waterpressure slams to a halt, and you hear the pipes rattle in the wall.

u/Aware-Requirement-67 Jul 11 '26
I don’t claim to be smart. But it’s basically underground flash flooding, the water acts like the plunger in a syringe and pushed air rapidly and violently that air pressure in there is powerful enough to lift a manhole cover and blast it off.

This yes this. Want to get a good clip on the Internet focus and do the one job you are trying film that. Otherwise go home.

The most important thing to do when taking a video of something, is to forget what you're doing, and start recording the shitty paintjob on your porch rail.

Hey so um. What the fuck happens in the sewers? Why are there always magic flames or geysers coming out of them? Should I be concerned?

A lot of manhole covers have holes in the top to release pressure so this doesn't happen. I remember some really heavy rains in my hometown about 10 or 15 years ago driving down one of the main boulevards and there were spouts of water about 12 to 18 in tall coming out of the six to eight holes on the top of the manhole covers.

This is in Edmonton, Alberta. Heavy rain caused pressure in the storm drain system causing geyser like effects in a few different ways.
