Urban Planning of Drainage in BTN Hamzy of Makassar City

Abstract

Drainage is generally defined as a technical measure to remove excess water which is not desirable in an area, as well as ways of overcoming consequences caused by excess water, so that the function of the area/land is not disturbed. Drainage problems in the BTN Hamzy of Makassar City, caused by a lack of ability to accommodate drainage discharge the water, there is also a channel that does not connect/disconnected with other channels, also less maintained and not maintaining the drainage channels. Location of study is on Housing Complex BTN Hamzy of Makassar City. The study discusses the causes of inundation occurred in the area due to lack of ability to accommodate drainage water discharge and less optimal catcher called inlet channels in capturing the existing water discharge. The analysis shows that there are 4 blocks of housing that have lower altitudes than the surrounding blocks, i.e., Block P, P1, Q, Q1, R, R1 and S, but the existing channels are not capable of removing water from the puddle. The method used is a channel dimension planning useful for normalizing existing channels and re-planning of inlet tracts and making absorption wells in the area
