An elongate ground gutter device designed to be substantially recessed in the ground with the central trough section thereof open above ground. The gutter device is designed to communicate with the downspout of a roof gutter to receive rain water into the trough section and transport it a distance away from the building. The gutter device comprises a trough section having vertical walls terminating in upper reinforcement sections which are supported on the ground surface, and a pair of lower horizontal flanges which are buried below ground, parallel to and underlying the reinforcement sections.
