A long time ago, I became fascinated by the mechanics of living in a city. I wanted to know what happened when you flushed a toilet. There weren’t any current books and there were new waste water treatment systems.
So I wrote the chemistry and biology of waste water treatment as well as the physical engineering required to move the water. Then as I waited for publishers to catch up with my enthusiasm, I researched new systems, and rewrote pieces that had changed. The book hits third and forth grade science but really is for any of us who want to know what happens.
It describes standard systems as well as new innovations including Living Machines and composting toilets. It’s not gross. It’s how we live. And it is cool science.
