With the Surface Detector array (SD) of the Pierre Auger Observatory we can detect neutrinos with energy between 10(17) eV and 10(20) eV from point-like sources across the sky, from close to the Southern Celestial Pole up to 60 degrees in declination, with peak sensitivities at declinations around similar to -53 degrees and similar to +55 degrees, and an unmatched sensitivity for arrival directions in the Northern hemisphere. A search has been performed for highly-inclined air showers induced by neutrinos of all flavours with no candidate events found in data taken between 1 Jan 2004 and 31 Aug 2018. Upper limits on the neutrino flux from point-like steady sources have been derived as a function of source declination. An unrivaled sensitivi...
