Description
Summary:The development of residential and office the North Bandung area led to the expansion of impermeable areas. This condition causes water shortage and increase surface runoff. The high demand for water in office areas increases the excessive exploitation of ground water and decreasing water table. One effort is to improve and maintain conservation of groundwater in cities by rainwater harvesting. The method applied is Low Impact Development (LID). This concept combines rainwater harvesting and artificial recharge to fullfill of water needed and to increase groundwater savings. One of the pilot locations is the LIPI Bandung office area. The purpose of this study was to determine the volume of runoff rainfall that occurred in this area. The analysis used is descriptive analysis with a quantitative approach. Rainwater harvesting volume is 1.2263.7 m3 / year which can reduce groundwater use by 1.02%. The media used to store rainwater is a reservoir that is installed in each building. The construction of artificial recharge from reservoir delegation serves to reduce surface runoff and increase groundwater storage. This method is expected to be a solution to reduce excessive use of ground water and reduce surface runoff to support urban groundwater conservation.
