Introduction

Environment III Pasar III Padang Bulan Medan, a city in Medan, is one of the areas prone to flooding. The reduction in rainwater catchment areas and non-optimal functioning of drainage systems have led to frequent flooding, causing significant losses for residents. Therefore, it is crucial to find effective flood management solutions that can be applied early. One such solution is the application of infiltration drainage systems, which can help mitigate the effects of flooding.

Background of the Study

Floods are a common occurrence in Environment III Pasar III Padang Bulan Medan, causing damage to properties and disrupting the lives of residents. The city's drainage system is inadequate, and the lack of rainwater catchment areas has exacerbated the problem. The government and related parties have been searching for effective solutions to manage floods in the area. Infiltration drainage systems have been identified as a potential solution, and this study aims to analyze their effectiveness in flood management.

Methodology

The study was conducted in Environment III Pasar III Padang Bulan Medan, and the following methods were used:

Soil Permeability Testing: Soil testing was conducted in a soil mechanical laboratory to determine the permeability of the soil.
Design of Infiltration Wells: The data collected from the infiltration rate and soil permeability testing was used to design infiltration wells with a diameter of 1.5 meters and a depth of 2.5 meters.
Simulation Results: The simulation results showed that with the absorption system of infiltration and infiltration wells, the flood discharge of a plan of 0.6283 m3/second can be reduced up to 40%. The infiltration well is also able to delay the flow of water for 1.45 hours before running to drainage, so that the flood discharge that comes out to 0.3745 m3/sec.

Results

The results of the study showed that the constant infiltration rate in the study area was 15 cm/hour, while the soil permeability value reached 8,97 × 10-4 cm/hour at a depth of 1.5 meters. The data was used to design infiltration wells with a diameter of 1.5 meters and a depth of 2.5 meters. The simulation results showed that with the absorption system of infiltration and infiltration wells, the flood discharge of a plan of 0.6283 m3/second can be reduced up to 40%. The infiltration well is also able to delay the flow of water for 1.45 hours before running to drainage, so that the flood discharge that comes out to 0.3745 m3/sec.

Discussion

The results of the study showed that the infiltration drainage system is an effective solution for flood management in Environment III Pasar III Padang Bulan Medan. The system is able to reduce flood discharge by up to 40% and delay the flow of water for 1.45 hours before running to drainage. The system is also able to reduce flood discharges in houses by up to 83%. The implementation of infiltration drainage systems in Environment III Pasar III Padang Bulan Medan is an important step in the effort to overcome floods.
