SUMMARY:

Water is an essential asset for the life of any human being. Its use in clearing the sanitary sewage network is a common practice in Brazil. Therefore, solutions are needed so that potable water is not used for this purpose, as it must be reserved for nobler uses, and its use in sewage collection network maintenance is not interesting. The objective of this work was the creation of a pilot project for the use of effluent reuse in services of clearing the sewage network. Data were estimated in the pilot project, which was designed to meet the CONAMA 430/2011 and CPRH NT legislations Nº 2002 and 2007*, in force in the state of Pernambuco, so that the effluent is classified as Class 2 reuse water. Based on the parameters stipulated in the pilot project and with the efficiency data obtained from the ETE Centro Petrolina (existing ETE), it was verified whether the unit was suitable for the use of effluent reuse in unblocking in the municipality of Petrolina. After verifying the feasibility of the study ETE and with the extravasation data obtained from the SNIS between the years 2016 and 2019, it was found that the cost of drinking water in unblocking services in these 4 years was approximately R$873,784.00, which made the reuse of treated sewage feasible, since the cost of implementation was approximately R$ 44,000.00. It was also demonstrated that if the municipality of Petrolina had chosen to reuse effluent from 2016 to 2019, there would be monthly water availability to supply 280 homes in the region. The environmental benefits of reused water were also listed, as well as tax incentives and improvement of the institutional image for companies that adhere to this alternative. In summary, the study was satisfactory for the use of effluent reuse in unblocking the sewage network, thus contributing to other units adopting this alternative to reduce their operating costs and to enable the use of water for noble purposes, such as supplying the population.
