Correlations between X-ray and water maser emission in AGN have been recentlyreported. However, the lack of systematic studies affects the confidence levelof these results. In the following, we introduce a project aimed at studyingall the water maser sources believed to be associated with AGN activity throughX-ray data obtained with the XRT and BAT instruments on-board the Swiftsatellite. Preliminary results of this work indicate a promising rate of XRTdetections allowing us to refine follow-up observing strategies focused oninvestigating the nuclei of individual galaxies and deriving, on statisticalbasis, the main characteristics of water maser hosts. In addition, across-correlation between our sample and the BAT 22-months all-sky surveyprovides an exceptionally high detection rate at hard X-ray energies whencompared to other AGN-related catalogs.
