Based on that the planning of the rainwater harvesting building is made of with a volume of 245 m3 with a dimensions of 7m x 7m x 5m and dimensions of infiltration wells with a diameter of 1,5 and depth of 3m. Planning of the rain water harvesting in the UNDIP area the cost of Rp 275.465.000 with the process of work for 29 days.
