SLIDE 39: Mulch

by Nate Downey

Finally…we get to the mulch. This is essential. It’s the sponge that absorbs the greywater, and it also acts as a biofilter. That is, it not only separates the useful water from the not yet useful particulate that might be present. After this separation, particulate can be brokendown by mycelium, bacteria, insects, etc. and be a source for all forms of life up and down (mostly down) the food chain. The mulched basin at the end of a well designed greywater system also prevents standing water as it simultaneously feeds the plant material in planted along the basin. (Stay tuned to the webblog for after pictures).
