Rainwater harvesting (PAH) is a method of collecting runoff that occurs due to rainfall and flows on the ground surface to store it in the earth, tanks, or small dams where it is used for various purposes. This study aims to analyze the potential. Modeling is done by using existing equations and entering it into a computer programming language, in this study the programming language used is matlab. The equations used are the existing hydrological analysis equations and the equations for calculating the accommodated rainfall discharge. The PAH model was designed to determine the amount of water discharge that can be accommodated and used as a source of clean water. The results showed that the application of the PAH system in Coblong District was quite effective as an alternative source of raw water. Because it can cover 86.76% of overall water needs. However, the PAH system can only be used when there is rain (rainy season) in the month (November - April), and is not effective if it is used during the dry season because there is no rain in the month (May – October). So that it cannot meet the water needs of the population during the dry season.
