The current water crisis in the state of São Paulo, which is the most populous and where the largest Brazilian industrial park is concentrated, has led users and companies to review their water use and reuse strategies. In the Brazilian case, the cultural aspect of water waste must be added to the problems of poor technical management of water resources. The reuse of water is for drinking or industrial purposes also requires a deep knowledge of water treatment and purification technologies and these techniques require the engineering companies experience and multidisciplinary knowledge for the correct choice of the best technological route. In this way, having low-cost water that meets quality requirements has become a strategic issue in industries. From this perspective, the reuse of treated effluents is a promising option. The reuse of water is a practice that aims to replace the use of drinking water in less noble applications, such as: irrigation, refrigeration, washing floors, discharges of sanitary ware, etc. The adoption of a correct effluent reuse practice should be carefully evaluated, and one of the key points is the determination of which quality parameters the treated effluent should meet. The establishment of these quality requirements is directly linked to the definition of the applications to which this water will be destined, and has a direct impact on the process to be adopted and the viability of the project. H2O Engenharia will be able to assist you in solving these problems, accompanying them during all the necessary steps to prepare a reuse project. H2O Engenharia is a company that acts in the national market in the area of ​​engineering and consulting and that adds knowledge and experience in the development of conceptual and basic engineering services of water and effluent treatment systems. By means of technical and economic studies, discussions with the client, from the stage of preparation and presentation of proposals, and after comparative studies of different solutions,

H2O Engenharia identifies the most appropriate system to be used, taking into account the specificities and customer, as well as legal and environmental requirements.
