And you don't have to go far to find this, actually. Those mobile homes might be a couple blocks outside of the nearest town. If the wind blows in the right direction, people in town will smell it. It's not like this "problem" is hidden, or anything. It's just a fact of life. That's just how it is.

And you buy a home upwind of the cesspits.

There's actually an interesting side-note here... the Tiny House movement has a sewage problem, as well. When I was building mine, sewage treatment was a real issue.

Most people go with a composting toilet, but that is still really a sticky issue for your common tiny house hipster. They are not used to being that close to their effluent.

I've seen many tiny houses that just pump into a hole (if it is far enough away to avoid inspections), or use nearby bathroom facilities instead.

And that's just for human waste.

Almost all the tiny houses I have seen pump the sink water out onto the ground or into a hole, and simply try not to wash anything in the sick that might be toxic or stinky or whatever.

The eternal maxim holds true: If you go far enough in one direction, you'll come back around the other side eventually.
