A method and system for waste water treatment and disposal includes the use of a sealed chamber having a plurality of sealed light transmitting windows and a relatively large basin connected to the chamber by a large multi-channel conduit. A large fan exhausts gases, humidity and odor from the chamber into a lower portion of the basin. An upper portion of the basin includes a multi-layer grid including layers of hydro stones and/or artificial hydro stones, sand, fertilizer and earth together with a plurality of shallow rooted trees. Any carbon dioxide produced by the waste water is ultimately converted to oxygen.
