The search for alternatives to rainwater harvesting has become increasingly important today, mainly in regions such as the Brazilian semiarid, where climatic adversities in the region cause long periods of drought. In this sense, several initiatives for the development of sustainable technologies have developed in the last years, with emphasis on the use of rainwater, through abstraction and storage in cisterns. Given the influence of the pluviometric regime of the region, it is fundamental to evaluate which sizing methods lead to more reliable results. Thus, hydrological data were collected from the municipality of Delmiro Gouveia, in addition to statistical data, from the families benefiting from the cisterns provided by the P1MC program (One Million Cisterns Program). With this data, several scenarios were created with variations of roof area and number of residents, so that the local reality can be represented more accurately. With the results of the various combinations of roof area and number of dwellers, the volume required for the cisterns was calculated using each of the methodologies analyzed. Then, a computer program was developed, simulating the daily water balance in the cisterns, throughout the analyzed period. At the end of each simulation, the program returns to the number of days when the demand was not met by each dimensioned cistern. In this way, it was possible to analyze which method has the best confidence results. Due to the great initiative of implantation of cisterns by the federal government, through the P1MC, it was also chosen to evaluate the reliability of the cisterns of single volume, given the different variations of characteristics presented by the beneficiaries of the program. As a result of the evaluation, a more efficient alternative was defined for the program, with the use of cisterns with varied volumes, according to each range of demand to be met.
