| Summary: | Along with the development of the era, the water demand is increased and the availability is increasingly limited. In 2013 - 2014, the average rainfall in West <br />
<br />
Java is 228.80 mm / month with rainy day is quite high which is 21.15 rain days per month. Until now, the rainwater management system in ITB Jatinangor campus still adopt the old paradigm of the drainage system which is to drain rain water as fast as possible to the nearest stream. This is unfortunate given that rainwater can be utilized on the surface by keeping them in Reservoirs, catchment areas, or even used as a source of clean water and drinking water. Therefore, in this project it is necessary to know the volume of rainwater that can be harvested by each building using hydrological analysis, and the type and the amount of <br />
<br />
water demand in ITB Jatinangor campus to determine rainfall utilization. After that, the buildings in ITB Jatinangor campus will be grouped based on the roof <br />
<br />
shape and rain water utilization which consists of landscape watering, clean water source, and drinking water source. Based on the results of laboratory tests <br />
<br />
of rainwater sample in the area of ITB Jatinangor campus, parameters that do not meet the quality standard is pH that is equal to 5.98. Therefore, the processing unit used is acid neutralizer and rapid sand filtration. The components designed in this rainwater harvesting system consist of gutters, downspout, firstflush diverter, storage tanks, and treatment units. The treatment unit used is different for each rainwater utilization. For landscape watering, further treatment <br />
<br />
won’t be necessary. Meanwhile for clean water, acid neutralizer and rapid sand filtration is required. As for drinking water, additional units are requiered in the form of purification unit, pressurized tanks and tap water |
