The existing drainage condition in Sapphire Regency housing complex is still not good overall. This is proven by the fact that there are still many sediment garbage deposits. Development that continues to increase and is not supported by the completeness of its supporting facilities such as drainage channels cause inundation problems that occur during the rainy season. So there needs to be a good drainage channel planning.
This study is a Drainage Network System Planning with a field measurement system conducted at the Sapphire Regency Pulosari Housing, Brebes District. Planning is done by analyzing calculations on Cross Section data and rainfall data so that the dimensions of the drainage channel are obtained. The results showed that the reuse period used in the planning of drainage canals in the Sapphire Regency Housing Estate was an 8 year return period. The results of rainfall analysis and analysis of household dirty water discharge can be the amount of discharge in the drainage channel is 0.1885 m3 / sec. From the results of the drainage channel planning at Sapphire Regency Housing, it is obtained the dimension of the ecomonic channel for drainage channels with a base width of B =
0.3 m and water height h = 0.293 m with guard height w = 0.2 m. |
