According to data from the National Water Commission, there are 653 aquifers in Mexico, of which 115 are overexploited. The present study will focus on the only overexploited aquifer in the state of Puebla, the Tecamachalco Valley aquifer. In the year 2018, it was classified as the number 41 most exploited aquifer in the country with a deficit of 63.36 million cubic meters. This is due to the increase of agriculture in the area, in which different crops are harvested, such as corn, beans, chili, among others, which were previously irrigated with surface water from the Valsequillo dam located in the area. The increment in water demand caused by the population increase and the irrigation zones, in addition to the contamination of the reservoir, caused that this water source was no longer sufficient and the extraction of groundwater in the area began. Therefore, this research aims to evaluate different proposals to increase the availability of groundwater in this area through artificial infiltration that help increase water levels in the aquifer, because it is expected that by 2030 there would be a critical condition of this water supply source. After analyzing various alternatives for artificial recharge in the aquifer, it was concluded that the technique of infiltration lagoons is the most appropriate, due to its lower cost compared to other techniques, aided by the geology of the area that facilitates the infiltration for aquifer recharge.
