The detection of Ultra-High-Energy (UHE) neutrinos is key for the understanding of cosmic-ray acceleration mechanisms and the identification of their astrophysical sources. The Surface Detector of the Pierre Auger Observatory, comprising 1660 water-Cherenkov particle detectors deployed over an area of 3000 km$^2$, has operated continuously for over two decades, providing some of the most stringent limits on UHE neutrino fluxes above 100 PeV. Neutrino identification is possible through the showers they induce, which are generally more penetrating in the atmosphere than cosmic-ray-induced showers and still retain an electromagnetic component when reaching the detector, even for large zenith angles. Exploiting these features, searches for both diffuse and point source fluxes have been performed. In this contribution, we will discuss the results from these searches and their implications for possible astrophysical sources.
