When you flush your toilet, you don't even give a second thought to what happens to sewage water in the pipe.

Work how fast it travels or where it goes.

But if you ever do, then you should hope that there will never come a day when everyone in the world flushes at the exact same moment.

But let's talk about a less grand example.

First, say, if you live in a separate house with two bathrooms than flushing, both of them at the same time won't do any harm at all.

Now that's boring.

Let's upscale.

You live in a big apartment building with centralized sewage system in older buildings, especially outside the U.

S.

You can still find this kind of drawer that opens up on a really huge vertical pipe or soil pipe.

That's where all the waste goes when you and your down and upstairs neighbors flush may sound gross, but you can even hear the waste water rushing past you when someone above presses the button.

So imagine that the whole column just decided to flush at the exact same moment.

There's a powerful waterfall occurring right in front of you, and it's good if it's just water, but people normally flush, not just for the fun of it.

So there's also toilet paper and, um, other less savory substances.

So it oh rushes down at high speed and eventually gets into the general sewage system of the city.

The pipes down below are much wider, so they could keep up with the flow.

But even so, the average diameter of the largest pipe, which is the one that goes straight to the waste recycling station, is about 10 feet.

That sounds like a lot, but it depends on the instant flow.

I'll get their cell anyway.

12 stories of unanimous flushes.

What happens first is probably howling.

And that's kind of scary thing is that all this wasted water create a pressure that most pipes would not be able to withstand.

So you'd be lucky if the pipe in front of you didn't burst right in your face.

Hey, don't picture this.

If the pipe handles it, though, it will still howl like crazy from all the strain.

But when the waist reaches the wider sewage pipes, it will go further.

Without much trouble, the piping will become gradually bigger in diameter.

because obviously it collects not only the waste from your building, but from all your neighborhood.

And the further it goes, the more soil pipes it service is.

Like I mentioned earlier, the largest pipe is the central one or several.

If you're in a big city right before the waste disposal and recycling plant, it will need a really serious inflow to get clogged.

And I mean the whole city level of serious.

Now imagine there's a town of 300,000 people.

Let's call it flushing tonigh Wyoming.

It's government invented a new holiday called Flushing Tonight Flush Day.

On this day, every citizen should honor the gift of civilization that is a sewage system and press the flesh button at the exact same moment.

The whole town is getting ready for the celebration colors.

Air flying bands are playing, and the large clock at the central square counts down the last seconds before the big flush.

321 go.

Everyone happily presses the button and the water starts flowing.

Remember the howling?

I mentioned well in a town of this population, it will probably not happen with many people living in their own homes with separate sewage systems, but it doesn't mean nothing will happen at all.

Quite the contrary.

At first there will be absolute silence, then, ah, kind of tremor, perhaps, as the sewer system beneath the town tries to cope with the enormous flow just to put it in perspective, one flush ejects about three and 1/2 gallons of water.

So that's 1,050,000 gallons of water for the whole Flushing Toa, same as one and 1/2 Olympic swimming pools.

And then, if you're lucky enough to be the resident, you'll see the waste water rising back in your toilet and fast U turn to the wash bowl and the bathtub and get even more jittery.

The foul smelling stuff rises there to bubbling.

You run into the kitchen awaiting a disaster, and you're right.

All the dishes you left for washing later are already have covered in the list.

Call it dark water you call the local plumber, but the line is busy.

Everyone is apparently having the same problem is you not knowing what to do.

You go to the window and oh, you see, the manhole lids have burst from their places and the stuff from the sewers starts overflowing the streets at the same time, you hearme or bubbling from behind you and you're afraid to turn around.

But you have to.

This site is unpleasant, to say the least.

The washing machine you left plugged in and ready, has overflown to and to add insult to injury, there were clothes left in it, but by my favorite T shirt.

The floor is rapidly getting covered in sewage water, and you have no other choice but to quickly slip on your mud boots and jump out the window of your house outside.

Although the air is fresher, the odor is still nauseated.

You wade through the ever rising dark water, along with the other residents of the town, seeking Ah, higher ground Toa Wait out the worst of it.

The whole town gathers on the highest hill.

There are manholes here, too, but the sewage waters don't overflow here because it's too high.

Thankfully, people are glaring at the government officials who proposed the idea in the first place.

But everyone understands it's their own fault, too.

You and the others watch your town flooded with waste water until it finally subsides, which takes about an hour after that, you grimly plod back down to count the losses and get to the cleaning The Flushing Tonight Flesh day has been officially canceled from now on, okay, that's one moderately populated town for you.

But what if we take it even further and make it a world flush day?

The TV and radio all across the globe count down the seconds before the huge event, Day or night?

Doesn't matter.

We assume everyone has been waiting for this and is prepared to press the button and there it iss The water merely rushes down the pipes on Lee to you guessed it get back to you.

But since the stakes are much higher now, the backlash will probably be a lot more intense.

You'd better stay away from anything connected to the sewage system because the flow is gonna become a spray.

If you don't fall back at once, you're going to take a really stinky shower.

But don't even think about running outside in the first minutes after the big flush.

It's not going to be safe.

The manhole covers will pop into the air like soda bottle caps, and the whole city will look as if it's full of foul smelling guys.

Er's Well, maybe not, but we don't know for sure right yet the worst is still to come.

The waste water recycling facilities won't be able to cope with the stress, and the pipes there will burst to remember that 10 foot wide pipe I mentioned earlier.

When it burst, it will literally explode upwards, raining down lumps of earth and water.

Be sure to stay as far as you can from there, will you?

Next, the flood will continue, and it will probably turn into an absolute stinky soon.

Ah, Mick, Oh, people will try to get as high as possible to save themselves from the smelly disaster.

Mountainous regions will become the safest on the planet.

People will hide on the peaks and in the hills until the worst ends.

Flatlands dwellers won't be so lucky, though.

Taking the brunt of the damage upon themselves, houses will float and people will have to hang on for dear life.

The flow will get steadily stronger, but in about 1/2 an hour it will start to subside.

It's hard to imagine the amount of trouble it will have caused, but you can say for sure that it will cost a lot to everyone in the world.

Recycling facilities and sewer pipe works will have to be repaired before anyone can use their bathrooms again.

And that's not to mention the repairs necessary to restore the houses, parks and whatever got in the way of the flush flood.

All in all, the picture is as unpleasant as it sounds and smells well.

I don't think that World Flush Day is a good idea after all, do you?

So let's just flush that idea right now.
