Hydrological modeling, using softwares such as the Storm Water Management Model (SWMM), has become a prominent tool to predict events in basins, helping to reduce human losses in disasters and avoid ineffective spending on works. This article aimed to present and discuss the application of the SWMM model to a case study of rainwater management for an allotment project with about 36 ha, in the neighborhood of Guaratiba/RJ. The preliminary design of a drainage network for the region was modeled by simulating an intense rainfall with a return period of 10 years and duration of 10 minutes. It was sought to integrate and compare the critical results found to the possible improvements resulting from the use of Low Impact Development (LID) techniques related to permeable pavements in the modeling. For the same return time, there was a decrease in peak flows of up to 34,53%, in addition to decreases in total volumes in the system of up to 28.73% for return times of 10, 20 and 50 years, demonstrating that the adoption use of LIDs in drainage projects generally permeates stages of softer floods.
