SUMMARY:

The accelerated growth of the urban population and industrialization is causing an imminent pressure on water resources in the environmental protection capacity of many cities. In the arid and semi-arid regions in the Brazilian Northeast this phenomenon has intensified, as they are considered regions where water is poorly distributed, with low availability and high waste. The objective of this work is to evaluate the potential for agricultural reuse through the quantification of sewage produced and treated in the municipality of Tacaimbó - PE. To this end, local productive planning is analyzed so that wastewater has an alternative destination, aiming to reduce water problems faced with the waste observed in water management, with emphasis on agricultural practices as a way to remedy them in a viable solution. This study was developed through bibliometric, bibliographic and documentary research. The supply, collection, systematization and interpretation of data took place under the supervision of technicians from Companhia Pernambucana de Saneamento (COMPESA) after technical visits to verify the existence of irrigation activities in some type of cultivation with post-treatment water. The databases of the Brazilian Agricultural Research Corporation (EMBRAPA) SOLOS and the Brazilian Institute of Geography and Statistics (IBGE) were also used. Therefore, with the information survey, an estimate was made based on 3 percentages of irrigation application efficiency, being 50% for an area of 6.51 ha and 38.57 ha; 70% for an area of 9.11 ha and 54.14 ha; and 85% for an area of 11.06 ha and 65.74 ha. With the research it was possible to conclude that, when prioritizing an irrigation method with greater application efficiency, significantly better results are obtained with the minimum flow rate in the WWTP (19.35 l/s) and the values of the minimum and maximum irrigated areas will be 11.06 ha and 65.74 ha, respectively; while for the maximum flow rate in the WWTP (33.03 l/s), the minimum and maximum irrigated areas will be 18.88 ha and 112.22 ha, respectively. The proposed solution has great sustainable potential, changing little the characteristics of the site, producing an effluent according to the requirement of the receiving body and providing the feasibility of reuse in the agricultural area for the municipality.
