The purpose of this study is The analysis of the pumping design and the Impeller for fresh water needs in UPT Management of The White Timber Rusunawa, the method used is quantitative, so data needed in the form of the numbers that occur. Water is one of the primary needs for human life, the need for clean water in a bulding is of great concern, since thr availbility of clean water in a bulding is an absolute tool that the users or the occupants take note, on A and B of the building in UPT Management of The White Timber Rusunawa was taken on an average of 49 LPM for both buildings and conducted a Total Head count of 116,27 M based on the length of the pipe and the losses, so at 2,7 KW. Then can be determined by each motor’s power by presenting safety to a factor of 1.15. Pumpa A and B Efficiency scores at 35% therefore, it can be taken to ensure that it’s pump’s efficiency is taken to ensure that it’s safety factor is high. So the result of the impeller calculations is in diameter (D_1= 0,137 mm) and out diameter ( D_2= 0,216 mm)( β_1=11)°, (α_1= 62°), (β_2=25°), (α_1= 20°) (ρ=33) mm and all sudu (z = 11). With the pumps specs used as input which is the speed of the motor = 2980 (Rpm), The level od sudu = 5 mm, and the level of shaft (S45C) = 58 Kg/mm^3. From the calculation could be concluded that the need for fresh water in buildings A and B must be met by the number of people in the bulding and there would be a pump with more precise spesification in order for demonstration to be more optimal.
