Indonesia has several water sources under community settlements, making difficult water distribution. Thesimple technology used to raise water from a lower place to a higher one is a hydraulic ram pump. Thisstudy aims to obtain the inlet diameter pipe concerning the height of the place and the time to raise thewater. The research method uses a functional design and tool performance test with three inlet pipesmeasuring 2.54 cm, 3.175 cm, and 3.81 cm. the inlet heights are 80 cm, 110 cm, and 140 cm, respectively.The results showed that inlet diameter affected the height of the place and the time to raise the water. Thebest inlet pipe measuring 2.54 cm can produce water discharge with inlet heights of 80 cm, 110 cm, and 140 cm. The ratio of the inlet and outlet discharge ratio is 5:1, while the maximum pumping height ratio is 1:5. The water discharge produced in Subak Bunut is 0.00831 liter/second with a distance of 20 meters and a maximum height of 470 cm.
