Abstract: In this study, the results of the works carried out in the Line 3 of the Light Train System are presented. The content includes several aspects about the hydraulic behavior of the Monterrey pore aquifer; Code CONAGUA 1906; being possible to determine the elastic parameters of the aquifer. The results obtained in the tests of long-term pumping (72 hours) in the wells: PB 1, PB 2, PB3 and PB4 allowed us to determine the following hydraulic parameters of the aquifer: mean transmissibility, storage coefficient, specific flow, hydraulic conductivity, permeability coefficient, radius of influence. By determining such parameters, it was possible to establish that the aquifer behaves as free. We consider that the aquifer in granular media has the capacity to deliver about (500 l/s). In the 3D block, the interdigitation of different lithology packages is observed. At some intervals, a clay domain is present, which reduces the permeability unlike the gravel packs with sands whose conductivity is very high. The aquifer in granular media is closely related to alluvial deposits of the quaternary and the recharge of this aquifer is regional. The preferred direction of the underground flow in the study area is southwest- northeast.
