Disposer wastewater treatment systems, comprised of food waste disposers and wastewater treatment tanks, are approved and have spread quickly in Japan. Direct discharge disposers, which discharge wastewater directly into sewer, are under consideration of approval by authorities. This paper therefore compares types of disposer installation using the life cycle cost analysis method. The LCC increased in all cases of disposer installation. In cases which involved 100 households or less the LCC of introducing direct discharge disposers was lower than that of installing disposer wastewater treatment systems. When disposer wastewater treatment systems are installed, user costs increase and waste/wastewater treatment costs to the public sector decrease. Subsequently, certain measures may be required, such as returning some of the public sector cost savings to users.
