The disposer wastewater treatment system, which combined with the household garbage disposers and the wastewater treatment equipment, has spread quickly in a metropolitan area. However, wastewater treatment properties of installed systems in a real houses has not been reported yet. In this paper we reported the 4 year survey of the system wastewater treatment properties and its household waste reduction effect. The system has installed for the 48 houses condominium in a major city designated by government ordinance. It was found the BOD and SS influent concentrations were always lower than the design standard concentrations and garbage weights discharged by houses were also 0.6 times as its design standard weight. And then, system effluent concentrations were sufficiently lower than the designed concentrations, 200mg/l. The disposers reduced the household waste to 0.6 times and made ease to classify the recyclable waste by making the rooms for temporary storage until municipal collection.
