Summary: 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. The difference between the total infiltration type PPBCP
implantation costs and the PCBC implantation costs varied from 3.93% to 19.66% for
soils with CBR values ≥ 8, while the difference between the implantation costs of the
Partial infiltration type PPBCP and PCBC implementation costs ranged from 19.49%
to 26.58% for soils with CBR values ≥ 5. The difference between the implementation
costs of the non-infiltration type PPBCP and the costs of implementation of the PCBC
ranged from 21.67% to 44.48% for soils with CBR values ≥ 2.5. The difference of
3.93%, found for PPBCP type total infiltration, shows that the implementation of
permeable pavement in residential subdivisions can be viable, once the restrictions of
infiltration rate, water table level and possibility of water table contamination are met.
