It's abit of work, and you need quite a footprint, but it's pretty simple
Your water goes to 2-3 plant "pools" in a precise order and come out clean at the other
Basic set up is cane+bamboo. You can tweak it to work with the soil and climate you have.
A friand of mine did this for his house, works fine.
