PROBLEM TO BE SOLVED: To reduce blockage to the conveyance of waste by discharging compressed air in a wastewater force-feed chamber in a short period of time, in a waste force-feeding apparatus in which waste dropped into a bowl part by wash water is force-fed and in which the wastewater force-feed chamber connected to the bowl part is located. SOLUTION: The wastewater force-feeding apparatus is provided which has an atmospheric relief valve for relieving compressed air in the wastewater force-feed chamber to the atmosphere so that during the period from the actuation of a washing switch to the time when wastewater in the bowl part flows into the wastewater force-feed chamber, the compressed air in the wastewater force-feed chamber is relieved to the atmosphere in a short period of time.
