Over time in the development of construction in Colombia, the roads and their drainage within residential projects have been commonly handled with conventional pavements, whether rigid or flexible. However, there are different road and drainage solutions such as porous pavements. For this reason, there is an interest to determine the financial benefit of the implementation of porous pavements in a residential project located in the Villas de Granada area of the city of Bogota. For this, the study site was characterized physically and hydrologically, the conventional and porous pavement structures were sized to be budgeted in different implementation scenarios, through a financial analysis that establishes possible savings. The financial analysis for the proposed scenarios shows that the most significant savings in percentage over cost is greater than 20%, mainly due to the elimination of all storm sewer. The diameters of the pipeline are directly proportional to the savings received and the return of the initial investment for the change of technology, represented in training and maintenance, has a repayment period of less than a month of time.
