The disorderly occupation combined with the lack of planning in the construction of cities resulted in an unsustainable scenario, where the interaction between man and the environment needs to be rethought. Regarding the management of rainwater, new concepts and processes have emerged in order to minimize the impacts caused by urbanization, in this context, the SuDS - Sustainable Drainage Systems appear. SUDs are sustainable drainage systems that prioritize rainwater control techniques at the source, among these techniques are permeable pavements that facilitate the infiltration of rainwater by reducing surface runoff, in addition to serving as a filter for rainwater and increasing road safety. Another great advantage of using permeable pavement is that it does not require extra space for its implementation, in subdivisions, for example, permeable pavement is applied on the streets and can be used in sidewalks, squares, parking lots, etc. Despite the vast list of benefits, permeable pavement is a little used drainage solution, on roads with low traffic, for example, it is common to use conventional concrete blocks. The present study determined the cost of installing a permeable pavement with porous concrete block (PPBCP) and compared it to the cost of implementing a conventional pavement with concrete block (PCBC), in the paths of a residential subdivision, noting that the implantation of the PPBCP can be from 5.23% to 46 .27% more expensive than the implementation of the PCBC. It was also verified that, in scenarios where the cost of the porous concrete block is reduced, the cost of implantation of the PPBCP becomes more attractive, reaching a difference of -17.22% in relation to the cost of implantation of the PCBC, when the conventional concrete block and porous concrete block prices are the same.
