The sewage pipe is obstructed.

Goo JungMool (sewage)? Or flies?

Often what jams us up is sewage.

Goo JoongPyo, you are Goo JoongMool (sewage)!

Literally, the raw sewage runs through the camp.

We've got some runoff from a sewage plant farm.

It flows down through Delhi, Mathura, Agra, and gets just about every bit of effluent you can imagine.

And what this project was doing was taking the effluent of these, and turning them into all of this food.

Closed because human sewage is so far over this park that you can't use it ?

We wouldn't tolerate our parks being swamped by human sewage, but beaches are closed a lot in our country.

In brains full of long sewage pipes of school wall, tarmac and welfare papers the buzzing of insects must enter.

And if we jam nutrients, sewage, fertilizer in the base of that food pyramid, it can back up all through it.

If you flush a toilet, your feces will go to the sewage treatment plants, which are sold as assets, not liabilities.

Imagine a restaurant that serves Michelin starred food, but actually where the restaurant smells of sewage and there's human feces on the floor.

More water comes down, the deforested areas, here in the Tarai, will be unable to absorb the effluent, because trees are like straws that suck up the extra seasonal water.

And I asked the real estate guy what it was as we were walking by, and he goes, It's something to do with the sewage system.

And when we were walking through the narrow alleys, it was literally impossible not to step in the raw sewage and the garbage alongside the little homes.

There are problems of sewage overflow and contamination, but I would also argue that almost every city has this exact condition, and it's a condition that we're all facing.

When she came into my life, we were fighting against a huge waste facility planned for the East River waterfront despite the fact that our small part of New York City already handled more than 40 percent of the entire city's commercial waste a sewage treatment pelletizing plant, a sewage sludge plant, four power plants, the world's largest food distribution center, as well as other industries that bring more than 60,000 diesel truck trips to the area each week.

Now, all these photos had been damaged by water, submerged in salt water, covered in bacteria, in sewage, sometimes even in oil, all of which over time is going to continue to damage them, so hand cleaning them was a huge part of the project.

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.

That's why we're starting to see more disclosure laws come out, so for example, on the environment, there's the Aarhus Convention, which is a European directive that gives people a very strong right to know, so if your water company is dumping water into your river, sewage water into your river, you have a right to know about it.
