In Rio Grande Norte, a state located in northeastern Brazil, the situation of water insecurity has been aggravated by long periods of drought. As a result, its largest water reservoir, the Armando Ribeiro Gonçalves dam, has suffered an alarming reduction in its volume, so the cities supplied by it are affected by serious water supply problems. In view of this situation, the desalination process of the water, whether salt or brackish, appears as an alternative to ensure the needs of public supply. Thus, as a proposal to overcome the water shortage in this region, this work aims to study the viability of the implantation of a sea water desalination system, using the reverse osmosis technique, in the municipality of Macau / RN. For this, a study was carried out through a pilot project with production capacity equal to 9,000 m³ / day, which proved to be effective to meet local demand. In addition, even with negative impacts such as the discharge of highly saline residue, the system has become advantageous compared to the current supply methodology, seeing the continuity and qualitative aspects of the water offered.
