The present research aims to study social technology in Mucambo, Pedra de Fogo, and Pajeú, based on an approach to the elements that make up the Coreaú Watershed. The Brazilian Northeast has been a region punished by the lack of water due to irregular rainfall. Such a problem, which has been part of the reality in that region, is, among other factors, accompanied by a population that shows resistance to the difficulties related to water conditions. The manuscript discusses social technology in the Mucambo outback, which stores water during the rainy season to be used by humans and in agriculture in the drought period. This aspect is significant because of the water shortage in the dry season in the location. This way, social technology grant water assistance to the population, providing security for this resource. The results highlight the social technology benefits, being the most significant water source for families living in rural areas. Given the research results, the cisterns are relevant for consumption and production in rural areas since people reported that they store water in good quality.
