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.

Some cities just release the water.

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.

Well, we decided to connect these two worlds the world of the companies with their water footprints and the world of the farmers with their senior water rights on these creeks.

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

You don't even have to look at those issues for nuclear to fail.

The next big issue, deforestation.

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

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.
