=Principles of Operation=
<!-- Only briefly state anything that the StemNode Diagrams can cover within subsystems.  This section is often omitted for specific systems (manuals on a specific make, model, or serial number) -->

Composting is assisted by worms, added 1 year after startup. Toilets are either waterless or foam based and sit directly above the composting unit. The waterless toilets connect to the composting unit directly via a 14” diameter polyethylene shoot. The foam flush toilets have a 4” hole at the bottom of the bowl with opens into the shoot. The foam flush toilets need to be “flushed” before and after each use. Ventilation occurs by drawing air down the shoot, through the composting unit, then up a vent stack. The system includes a compost tea tank and removal pump that allows for the compost tea to be stored and distributed for land applications.

==Operating Specifications==
===Capacity===
<!-- Typically used for specific systems (ones that have a make and model) -->
A single unit is rated for 18,000 to 65,000 uses per year.

===Requirements for Operation===
<!-- Only briefly state anything that the StemNode Diagrams can cover as inputs. Use metric base units (Kg, L, m, A, cd, mol) where practical, with the exception of temperature which should be in Celsius instead of Kelvin. Chemical and biochemical processes should be in molar ratios.-->

'''Composter'''
Moistening system: 1 gal/day. Works on in house water supply so no additional pump is needed. Solenoid is 120 VAC, 50/60 Hz. There is no heating system. Liquid removal pump - pumps compost tea to storage. Operates ~4 min/day. - 115V AC, 5 Amp, 20.4 gpm. 62Wx105Lx58.5H inches, 132 cubic feet. Wood shavings should be amended into the compost, but these can be procured from local waste sources (cedar should not be used). 

'''Toilet'''
Two toilet options exist; a waterless toilet or a foam flush which requires 0.2 L per flush plus a foaming agent (~185 USD/year). The foam flush requires an electrical connection. Non-potable water can be used. Fan: 115 V, 0.67 amp, 71 W, 60 Hz, 243 cfm, runs continuously.

'''Compost Tea Tank'''
500 gallon volume.

===Ratios of Inputs to Outputs===
<!--Use metric base units (Kg, L, m, A, cd, mol) where practical, with the exception of temperature which should be in Celsius instead of Kelvin. Chemical and biochemical processes should be in molar ratios. Alternate units can be placed in parentheses -->

==Known Failures and Solutions==
<!--Historical significance of a failure is better suited for Wikipedia or other sites.  You are encouraged to link out to these sites from this section.  --> 

<!--Problems are user oriented since a problem to one entity may not be a problem to another, Symptoms are an observable, and sometimes measurable trait, Fundamental causes connect the problem with subsystems or symptoms, and Solutions are actions that can be taken to remedy the problem -->

{| class="wikitable sortable"
|-
! Problem
! Symptom (s)
! Fundamental Cause
! Solution

|-
|Failure of refuse to break down
|Increased accumulation of material in the composter
|Bulking agents need to be high in carbon, low in nutrients, and rapidly degradable. Naturaly resistant bulking agents (e.g. Cedar) should not be used. Further, adequate air flow is needed to ensure break down. 
|Check bulking agents and change if needed. Check ventilation system for blockages.
