FIELD STUDY 22 The Living Machine © North Guilford Middle School As part of our design study, several students organized a field study in order to investigate the process of water retention and filtration systems that make up The Living Machine©. The process of the Living Machine consists of an overflow effluent from the septic tank into equalization tanks. The tanks, which are located adjacent to the school, are completely submerged, leaving the green lid as shown to the right , as the only indication of their existence. The last tank shown has a carbon filter fan on top to neutralize unpleasant odor.
