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

Michael Pritchard Okay.

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

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

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.

It has to substantially eliminate emissions of ammonia, nutrients, pathogens, heavy metals, odors, and have zero discharge of wastewater to ground or surface waters.

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.

Under Los Angeles is a vast and intricate system of huge storm drains... built to siphon off the flash floods of the rainy season.

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

Dr. Adam Neiman.

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

Well, that's the future we have to look forward to.

This water is significant, but it isn't available for human use in a regular way.

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.

The water is welling up from the ground.

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.

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.

Second, ice caps and polar regions freeze up to 70 of the planet's fresh water.

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.

Agriculture uses 60 times more land than urban and suburban areas combined.

Earthquake, flood...

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

All abscesses should be drained, period.

First, surface water.

This was the full size of the original creature.

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?

San Francisco is also spending 40 million dollars to rethink and redesign its water and sewage treatment, as water outfall pipes like this one can be flooded with seawater, causing backups at the plant, harming the bacteria that are needed to treat the waste.
