Greywater reuse is an important alternative for reducing potable water consumption in airports. The objective of this study was to assess the quality of greywater produced in airport environments and the reuse potential of such effluent. This study was developed in a mid-size airport in Brazil, where a qualitative assessment of greywater produced by different activities was performed. The results were analyzed using descriptive and multivariate statistics. Greywater production in the administrative buildings was estimated by the application of questionnaires and interviewing employees, and compared to the nonpotable demand in these buildings. The results showed that the quality of the greywater produced in the airport is similar to that produced in residences and can be easily treated for reuse purposes. In quantitative terms, greywater reuse can meet the non-potable demand and provide great savings of water and financial resources, in addition to priceless environmental benefits.en-USGreywaterReuseAirport environmentsRational water useArtigo publicado em periodicoO periódico Resources, Conservation and Recycling concede permissão para depósito deste artigo no Repositório Institucional da UFOP.
