The grinder developed during this study reduces most of the components of household refuse into a slurry formed with the nonfecal component of household water and transports it through the house sewer lateral to the sewer. The system requires a modification in household plumbing and a storage tank to separate and store the nonfecal component of waste water. The grinder design as conceived would be capable of grinding most of the components of household refuse. The grinder design will accept heavy aluminum and steel cans without damage to the machine, but will not grind them. It will clean the cans of putrescible matter and more than likely crumple them to a smaller volume. Simplicity of design, jam free operation, and low cost were achieved within power limitations. Economic analysis of grinder and plumbing modifications are discussed.
