Michael Pritchard Okay.

They had pumps to keep the water out of the foundations.

Some cities just release the water.

They literally flipped the switch.

Tunnels leads to the sewers, sewers lead to the storm drains... Storm drains leads to sea.

I want a map covering the storm drain system in this area.

You can get a drainage grant these days.

We drain it and she'll fry.

The school drains the pool once a month.

Lately he'd been living in one of the downtown storm drains.

Sewage treatment facility.

It's less likely but sometimes a plaque could also go downstream, kind of form a thromboembolism.

When I unplugged the bathroom sink, the water gushed down the drain.

Thanks, when we want your help, we'll get out the drain cleaner.

The waste water that leaks out is water that already now goes into that coastal environment, and the algae that leak out are biodegradable, and because they're living in waste water, they're fresh water algae, which means they can't

It would be this thrombogenic material, the clots around it.

I want a man at every other drain entrance along this line.

So different cities around the world treat their waste water differently.

It leaks. It's struck by lightning.

He'll head down this drain to where it comes out of the Rio Hondo.

All drains lead to the ocean, kid.

This is the city of San Francisco, which has 900 miles of sewer pipes under the city already, and it releases its waste water offshore.

This actual clot that forms, that can restrict the blood vessel, this is a thrombus.

So, in fact, it's not permanently in the high seas.

Now how many of you have ever gone to a state park or a national park where you had a big sign at the front saying,

So let me show you how the system works.

Here's an image of what we could do in San Francisco Bay.

Yes, we are less prone to falling sick.

They were not related to her, but they tried to find out,

Don't worry. All drains lead to the ocean.

The Pearl was listing to scuppers after the battle.

The dome has an incredible amount of water that washes off of it, as well as wastewater.

A bottle opener.

Your ears!

Then after every episode, I had to go up to the bathtub and swim around the bathtub and look at the drain, because that's all there was to look at.

Looks like he was washed down the entire length of the runoff channel.

And then the faucet is a beer tap.

I'm looking for the bottle opener.

Do they, perhaps, include green infrastructure, so that we can take runoff and water that's going out of our houses and clean it and filter it and grow urban street trees?

Big structures often had drainage tunnels into the sewers in case of flooding down in the subbasements.

What we drew in the last video and this one as well these emboli that are also clotted, they are also thrombi and emboli at the same time, this would be called a thromboembolus.

So, thromboembolus is a more specific way of calling it an embolus, and once one of these things lodge themselves and block the blood flow, that's a thromboembolism.

The stopcock's turned off.

The main tap is turned off.

The main valve is turned off.
