Abstract
The Metropolitan Area of Guadalajara (MAG) experiences water shortage and overexploitation of aquifers. In addition, it suffers from seasonal flooding that is channeled towards inadequate sanitary drainage, creating a strong negative environmental impact. These problems are rooted in the waterproofing of the urban surface. Many cities around the world have used deep injection wells to recover aquifers and remove surface waters. Certain geohydrological conditions are required for the implementation of these deep injection wells, deeper than 30 m, such as significant surface runoff, acceptable water quality for infiltration, considerable depth in the phreatic levels, and good subsoil permeability. All of these conditions exist in the MAG or could be achieved without significant investment. An assessment is presented exploring the viability for a solution based on this technology, as a strategy to recover aquifers and reduce flooding. The first step was to identify, through map algebra, a micro-basin suitable for this technology. Then, mean runoff volumes were obtained and a stratigraphic profile was carried out based on 19 standard penetration tests (SPT). With these data, a numerical simulation of deep injection wells of different dimensions was performed, providing recommendations for a solution based on these calculations. The results show that both problems can be solved with this relatively simple and cheap technology supporting public health.
Highlights
The projected scenario is one of a rapid reduction in both quantity and quality of the available water, increasing water emergencies, more conflicts related to rights and access to water resources, and a decrease in industrial, economic, and agricultural development, as well as the inherent negative environmental impact [1–3]

Summary
2.2 million km , encompassing a total area of 38.6 million km , affecting 4000 million people. According to this assessment, the main reason for this is the inadequate management of the water resources. The main reason for this is the inadequate management of the water resources This situation is exacerbated in developing countries, where minimal volumes of water are treated and recycled. The projected scenario is one of a rapid reduction in both quantity and quality of the available water, increasing water emergencies, more conflicts related to rights and access to water resources, and a decrease in industrial, economic, and agricultural development, as well as the inherent negative environmental impact [1–3]. It was predicted that this solution will not allow for the increasing water demand due to population and economic growth [3]
