Flooding is a problem that often afflicts Grogol Subdistrict, Sukoharjo Regency, Central Java Province, this is due to the lack of efficiency in drainage performance, it is necessary to make a rain flow model to control the performance of the drainage system. IPO Model (Input Process Output), a model for handling flow in drainage channels. The purpose of this study is to develop a model of rainfall flow to analyze the performance of the drainage system, to solve drainage problems in Grogol District, Sukoharjo Regency. Calculations are made using daily rainfall data for the past 15 years from 2002 – 2017. The most appropriate Frequency Distribution is the Normal Method, used to look for plan rains with a return period of 2 years, 5 years, and 10 years in the Frequency Duration Intensity (IDF) curve. Based on the rainfall intensity, it is calculated using the Rational formula so that it gets a plan debit every return period, in this case a 10 year return period. Based on the results of the study, almost all drainage channels experienced overflow due to back water, pumping is needed. In this study the pump calculation is performed using the water jump formula. Some sub-systems require additional pumps, including; (1) Langenharjo 3 pumps capacity 1 m3 / sec, (2) Dlopo Barat 2 pumps capacity 0,63 m3 / sec, (3) Grogol 2 pumps capacity 0,63 m3 / sec, (4) Kadokan 2 pumps capacity 0, 63 m3 / sec, (5) North Pandeyan 2 pumps capacity of 0.63 m3 / sec, and (6) South Pandeyan 2 pumps capacity of 0.63 m3 / sec.
