The purpose of this basic research was to produce well-grounded data concerning the feed water conditions required for ensuring the carrying performance of the horizontal drain pipe when waste water containing food waste, which has been disposed of using a food waste grinder, runs down the horizontal drainage pipe and subsequently to acquire basic knowledge with the intention of formulating an evaluation method of such carrying performance in the near future. In this initial report, firstly, the form of the horizontal fixture pipe used for existing apartments was analyzed and models of pipe layers of various types were set up for the drainage experiment. Next, different effects were created on the pipe layer models, which related to the flow rate of the water supply, the amount of food waste, the pipe's gradient etc. and which affected the carrying performance of the pipe layer models. The distribution of the remnants of ground food waste in each pipe was observed during the experiment and results were classified into several patterns. Finally, the relationship of each distribution pattern with the minimum requirement for the flow speed and the proportions of food waste and water in the waste water, both of which determine the distribution pattern, were evaluated quantitatively. The basic data was produced based on the results of the experiment mentioned above to be used for evaluating the carrying performance of the horizontal drain pipe.
