| Sumario: | The university campus presents water problems: flooding during the rainy season, shortages, and water cuts. This work evaluated the possibility of restoring the urban hydrological cycle through lid technologies in an area with low precipitation. The following hydrological variables were established for the design: annual rainfall for an arid year (181.1 mm), the average rainfall of 15.09 mm, a maximum of 53 mm, and a minimum of 0 mm. The volume of rainwater harvestable on roofs was calculated; runoff coefficient (concrete, C = 0.9); average daily toilet consumption. The storage system was dimensioned and the number of days in which the demand is satisffed as non-potable water. The volume of average runo (Vm) in parking lots and roadways with asphalt surfaces (C = 0.8) and concrete walkways (C= 0.9) was calculated and compared with the Vm if they were replaced with permeable pavement (C = 0.7). Also, infiltration capacity in green areas was determined. Through a conceptual model, it is explained that there is the potential to restore the urban hydrological cycle by combining LID: the annual demand for water in sanitation can be satisfied by 10.68%; the volume of average runoff is reduced in parking lots by 97.9%, 12.5% in the road circuit, as well as 22.2% in walkways. |
