Water social technologies: case study of the cistern project in a school in the municipality of Barbalha, Ceará

Rainfall in the regions of the northeastern semiarid region presents a poor spatial and temporal distribution. Thus, to minimize the effects of water scarcity, water social technologies were adopted through public policies. The objective of this work was to evaluate, through the case study technique, the potential of the cistern project in the school involving the promotion of water sustainability. The research was developed at the Elementary School Coronel Gregorio Callou, located in the municipality of Barbalha, Ceara. It was possible to verify how the water social technologies have the potential to change the water reality of a region, particularly in rural areas, being an effective alternative for the water supply of populations suffering from long periods of drought. The cistern project in the school assumes remarkable relevance, since it corresponds to the improvement in the access to an essential service that is the quality of the water, through the capture and storage of rainwater.
