Green Machine
The Hawaii Nature Center, Makiki Oahu, Hawaii


The Green Machine (formally known as the Pilot Living Machine) is a tank-based constructed wetland wastewater treatment facility located in the Makiki Valley State Recreational area in Honolulu, Hawai‘i.  It recycles wastewater from the Hawai‘i Nature Center for irrigation on-site in nearby fields. Constructed wetland technology uses the biology of Native Hawaiian wetland plants and bacteria to purify water.  REDI works with Partners in Development to provide educational opportunities at the Green Machine for learners of all ages to learn about natural treatment systems and bioremediation.
