OMS indicated that a person should consume 100 liters of water per day to satisfy their needs. In some districts of Lima, the consumption of this resource is much higher, while elsewhere the consumption is under of the recommended. In this study, we realized an evaluation of the consumption of drinking water using the grey clustering method, which is based on the grey systems theory. The case study was carried out in 32 districts of Lima, Peru. As a result, a map on the situation of drinking water consumption was obtained. The results revealed that the districts that consume more water are San Isidro, Miraflores, La Molina, San Borja, and Lince. In addition, the districts that consume less water were Ancon, Puente Piedra, Villa el Salvador, and Independencia. Moreover, the results of the study could help to the central government or the authorities of districts to make the best decision about the equitable distribution of water to all districts of Lima city. The Grey clustering method showed interesting results and could be applied to other problems of the country, since this method considers the uncertainty into its analysis.
