We examined estimation method of drainage piping systems in order to apply wastewater treatment systems with food waste grinders to real high-rise appartment houses. The piping systems were set up in the high-rise experimental tower, had drainage stack of 90m height and house drain of 90m length, were supposed the models in real buildings. In this study we investigated how facters influence the performance and pressure in branch, were 4 types forms of drainage fittings, and 2 types diameters of grind garbage particles or characteristics of discharge by food waste grinders. Further we examined influence of offset in lower floor, relief vent pipe for back pressure in stack closure at the bend, and house drain length. As a result, special drainage fittings systems are able to decrease negative pressure than usual sanitary T fittings system, using food waste grinders break to pieces finely are able to decrease positive pressure than using its break to pieces roughly, and offset has effect of making horizontal transport smooth, were found.
