Abstract

Rawa Makmur Village, especially Merpati I, has an area of 3.6 hectares, has experienced land use changes of 30% in the last 3 years. The purpose of this study is to design infiltration wells to reduce inundation that often occurs in this region. The data used are primary data (soil sampling and laboratory testing) and secondary data (rainfall data, land use data and other supporting data) that are processed using hydrological analysis and hydraulic analysis. Based on the results of data processing obtained the intensity of rainfall with a 20-year return period is 2.56 mm/hour and the flood discharge plan is 0.01229 m3/s. The household debit is 0.212 m3/s, the roof discharge is 0.00000037 m3/s, so the total debit that must be reduced is 0.222 m3/s. The soil sample at the study location is taken and tested in the laboratory. The test results show the soil permeability coefficient is 2.630 x 10-4 m3/s. Infiltration discharge into the soil is 0.000152 m3/s, then the reduced discharge is 0.2218 m3/s. Based on the analysis results obtained the design of infiltration wells with a diameter of 1 meter and a depth of 2.2 meters. One well was effectively used for 2 houses with a reduction of 0.2218 m3/s with a reduction time of 1,297 minutes.

Abstract

The purpose of this study is to determine the feasibility  of the drainage system outline plan based on the Regulation of the Minister of Public Works and Public Housing (PUPR) number 14 of 2018 in Rejang Lebong Regency, especially in Curup District. Based on the results of the feasibility test analysis  of the drainage system outline plan in Curup District, it was found that the condition of the drainage system was categorized as feasible. Waterlogging that often occurs due to closed drainage channels and buried in soil. Then, in the category of infrastructure and wastewater treatment facilities are declared infeasible because based on the outline conditions   the capacity of drainage channels amounting to 0.0417186 m3 / s  cannot accommodate dirty / waste discharge originating from population activities, which is 56,442,2006 m3/sec.
