Well, you'd assume that that would be the obvious thing that you do, right? But in my experience, usually they don't do that too much just because things evolve so fast. So especially I talk with a lot of people in the transit industry. And when you look at how they handle a system in New York, Boston, D.C., Chicago, often it's going to be pretty different.

So again, you would assume that they get together and that there's a one common system for everywhere, but often it's not the case. Water is another good example because the way that you treat your water really depends on your quality of the raw water that you get. And so there's no way you can have the same system in New York as in Chicago because the quality of the raw water is different.

Wastewater is my favorite infrastructure of all. By training, I'm more of a transportation person, but wastewater is what I prefer because it's incredibly complicated because you don't have one wastewater, you have two. There's the wastewater that we think of, which is the toilet, the showers, whatever we do at home. But there's also the wastewater coming from the rain.

So that's called the stormwater. And so in older cities, you tend to have combined sewer systems. So you have one single pipe in the middle of the road that has to handle the sanitary sewers from people and the stormwater from the rain. And in newer cities, they tend to be separate. And so depending on the type of system, you'll have different strategies.

But usually what you want when you have a separate system is to treat the water that comes from homes, and you don't really treat the water that comes from the storm. But in systems, in cities with the combined sewer, then you treat everything.

And so that's where you have to go to a wastewater treatment plant, you treat all the water that's coming in, and then you put it back into the environment in usually a way that's clean enough where it will not harm anyone or the species or animals downstream, but not clean enough that you can drink readily out of it.

So that's a great question. So the first thing you do is you're going to try to separate some of the solids. So again, screens. Sometimes you might have, again, branches, water bottles, toilet paper all you have. You try to screen everything that you can physically out of it. Then you put some chemicals to favor something called flocculation. So you have all those particles that are there.

Those particles tend to be negatively charged. So essentially, no matter how long you let it sit there, they're like little magnets that just expel one another. So it's never really going to sit to the bottom of a tank. And so you put some chemicals to neutralize that negative charge, and then you just let gravity do its job.
