Déjà Poo: The Living Machine Sewage System
This eco infographic is great! Better yet, this idea is being implemented! Published on Wired, they reported that the Port of Portland has incorporated the “Living Machine”, which uses soil and bacteria to filter out pathogens and turning wastewater into nonpotable water. But the signature element of the system is the plant life that grows up and out of it—right into the lobby. It’s awesome!
This is how it works:
- toilet water goes into a septic/holding tank
- the overflow gets pumped into “wetland” cells where water, pathogens, and biological content are absorbed by the plants
- whatever that’s leftover is treated with UV light and sent to a storage tank
- water in the storage tank is used in the toilet…..
- repeat steps 1 to 4
