520			_aThis study was conducted to analyze the existing drainage system of Barangay. 4 San Bartolome, San Nicolas, Ilocos Norte. This study proposed a drainage system plan that can cater check capacity and prevent flooding in the area. The data gathering procedure of this study covered three main segments: obtaining rainfall data, elevation model, and CDRA report during typhoon Egay, mapping of the elevation model, and simulation and validation of simulated data from actual conditions using EPA-SWMM. In analyzing the existing drainage system, particularly the flooded areas, the surface runoff was evaluated. Conduit dimensions and slopes that are inefficient to contain water runoff are also assessed through EPA-SWMM software using the 25-year return period. In the design of proposed drainage system, rerouting, modification of conduit dimensions, and incorporation of storage tank and pump link were piloted. Simulation results of the existing drainage system showed that 5 conduit links surpassed their capacity, leading to localized flooding at those areas. Localized flooding had a cumulative discharge volume of 72,244 cubic meters throughout the observation period of 3 days. Additionally, 19 out of 38 conduits are insufficient in catering water runoff making allowance for freeboard. Drew on the assessment of the existing drainage system through simulation, six (6) trials of conduit dimension adjustments were made. Successful trial results showed that all 49 conduits were adequately calibrated to accommodate runoff water while maintaining sufficient freeboard. Based on the analysis of the existing and design of the proposed drainage system, the researchers concluded that particular existing conduits were not adequate. Therefore, the incorporation of the proposed drainage system that can adequately accommodate water runoff considering freeboard is needed.
