The Surface Detector Array of the Pierre Auger Observatory consists of more than 1600 water-Cherenkov stations deployed in a triangular grid with a spacing of 1.5 km and covering an area of 3000 km2 . Fromthe recorded signals and their timing we reconstruct the impact point, the axis of extensive air-showers and the lateral distribution of the particles on the ground. When the impact point of the shower at ground is close to a detector, the dynamic range of the recording electronics is smaller than required to record the Cherenkov signal produced by the particles. We present an off-line recovery procedure developed to estimate the signal in case of saturation. We will discuss the performance of this method and the implications for event reconstruction.
