I am trying composting in stock tanks. The cost is high--about $700 for three 350 gallon stock tanks, three muck buckets and a
compost crank. It might be useful in dry climates to reduce evaporation, and to collect leachate and put it back into the compost when it dries out or use the leachate as compost tea. (My rain barrels are empty, I don't have a well, and keeping my compost moist enough to not start a fire is a priority). Some departments of making you sad might approve this compost system for use near wetlands or wells....? In my case, I am trying to put ALL of my domestic "waste" water into my compost so that there literally is no waste--just water vapor, oops! ammonia and nitrous oxide, and compost (which I test to verify that pathogens have been reduced to less than 1000 fecal coliform bacteria most probable number per gram which is the limit in Washington State for compost).
