The purpose of this basic research was to produce well-grounded data in order to determine the flow speed (minimum flow speed) inside the horizontal fixture branch, which is required for securing the horizontal fixture branch's carrying performance when waste water containing food waste disposed of using a food waste grinder runs down the horizontal fixture branch. The research concluded after taking two major stages. First, a basic pipe work (using 10m long linear pipe) was arranged and its carrying performance was examined in different conditions created on the pipe work with various factors related to the flow rate of water supply, the amount of food waste, the pipe gradient etc. affecting the carrying performance. The status of the remnants of ground food waste in the pipes was studied according to the conditions given to the pipe work and the records were classified into patterns. Secondly, the minimum flow speeds were calculated using both experimental and previous calculation methods and the results were studied in comparison, based on which the basic data was produced to evaluate the carrying performance.
