A hydrogeological study was conducted in the Condado neighborhood in Quito Ecuador, in order to provide drinking water in this area. The aquifer is confined, multilayer type with complex geometry and boundary conditions, several pumping tests were carried out to obtain the hydraulic aquifer parameters, and a numerical model was implemented simulating various pumping scenarios, including existing and future wells. The aquifer recharge comes mainly from the mountainous zone, in the urban zone is mainly artesian, and an average recharge of 380 L/s was obtained through model calibration. The mean aquifer thickness is 200 m, with approximately 947 million m3 of water in storage. The mean aquifer sustainable yield obtained for the next 25 years is 480 L/s was obtained, including 20% of water from storage.
