Stormwater Harvested from Permeable Pavements as a Means to Save Potable Water in Buildings

The main objective of this work is to analyse the potential for potable water savings in university buildings by using stormwater collected from permeable pavements. Six located on campus Federal University Santa Catarina (UFSC) were selected obtain monthly consumption patterns and parking lot areas. same six then evaluated considering their location eight different cities Brazil, with rainfall patterns. Simulations computer programme Netuno run each building city combined. structural design pavements was also assessed two methods available literature, that is, American Association State Highway Transportation Officials (AASHTO) Brazilian Portland Cement (ABCP). hydrological-hydraulic pavement carried out. designed thicknesses compared obtained Permeable Design Pro. between 18.4% 84.8% obtained, depending city, non-potable demand considered. For design, both similar; however, it observed AASHTO method better represents model. Regarding differences show simplification performed drainage favour safety. In conclusion, use harvesting systems promising, aligning aid, capacity saving water.
