Flooding caused by heavy rainfall is more than what it can handle. When there is a typhoon and heavy rainfall, the water level rise very quickly. The pumping stations cannot handle that much water, and can’t keep up with the water levels. Over time, they have debated about putting in rainwater harvest systems. Rainwater harvest systems are containers that collect roof…show more content…
In 2012, Campisano and Modica created a dimensionless methodology for the best design of domestic rainwater harvest systems. From these studies, it can be proved that the previous research had poorly designed the intake of the rainwater harvest systems. The size of the designs of rainwater harvest systems were kept in small communities. They also lacked consideration of all metropolitan catchments varying in special capacity and quality of the systems. The second category in rainwater harvest systems is simulation and evaluation of the effectiveness. First the research included evaluating the possible potential for safe to drink water savings by using rainwater in residential areas. The second thing that was in the research was estimating nonpotable household potential. With the performance of storage type, and investigating the potential benefits from sharing rainwater harvest systems with neighbors by using rainfall data. Establishing the probabilistic relationships between storage capacities and deficit rates of rainwater harvest systems was some of the next things that were used to consideration. These studies weren’t really considered for the surface and sewer flowing after rainwater. There are many studies evaluating the performance and reliability if rainwater harvest systems using numerical or hydrological models. Jones and Hunt figured
