Abstract

ABSTRACK
Drainage is a very important system for channeling rainwater. Some drainage channels in the Semarang City area can no longer accommodate rainwater, causing flooding in several areas of Semarang City. The Sub Kali Jetak area is a sub-area within the BKT Sub-System that needs to be evaluated because there are
still several reports of flooding in the Sub Kali Jetak area. A Design Review is necessary for the planning system of Sub Kali Jetak to assess whether the channels can still accommodate water runoff. The methods used in the drainage system planning for Sub Kali Jetak in Semarang City include the collection of primary and secondary data, as well as conducting hydrological analysis, spatial analysis, and hydraulic analysis to determine the dimensions of the drainage channels.The planning of the Sub Kali Jetak Drainage System produces longitudinal hydrological analyses for primary, secondary, and tertiary channels. The drainage system planning for Sub Kali Jetak uses the application of the Sustainable Urban Drainage
System (SUDS), and the selected SUDS planning is Infiltration Wells with well dimensions of 3m in height and 1m in diameter. In addition, the drainage system uses normalization so that there is no water runoff in the Sub Kali Jetak area.
