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 3000km2. Fromthe recorded signals and their timing we reconstruct the impact point, the axis of extensive air-showers and thelateral distribution of the particles on the ground. When the impact point of the shower at ground is close to adetector, the dynamic range of the recording electronics is smaller than required to record the Cherenkov signalproduced by the particles. We present an off-line recovery procedure developed to estimate the signal in case ofsaturation. We will discuss the performance of this method and the implications for event reconstruction.
