Built Components
In tropical and temperate climates, Living Machine systems can be outdoors, as the temperature will sustain sufficient biological activity throughout the winter. In cold climates, a greenhouse is used to keep water temperatures warm so that plants do not winterize. Supplemental heating may also be necessary.
Living Machine systems use screens, biofilters, plumbing, large plastic tanks, reed beds, rocks, fans, pumps and other mechanical devices. Every system is tailored to the volume and makeup of the sewage. Some are stand-alone greenhouses, while others are built into larger buildings.
John Todd and James Shaw have a patent on a device called an "ecological fluidized bed" which is essentially a pumice-filled tank with a concentric inner tank that contains wetland plants. Pumps rapidly recirculate water to maximize the filtration rate of this device.

Famous quotes containing the words built and/or components:
“Vashtar: So it’s finished. A structure to house one man and the greatest treasure of all time.
Senta: And a structure that will last for all time.
Vashtar: Only history will tell that.
Senta: Sire, will he not be remembered?
Vashtar: Yes, he’ll be remembered. The pyramid’ll keep his memory alive. In that he built better than he knew.”
—William Faulkner (1897–1962)
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
