Abstract: A combined fence and irrigation system is formed by a plurality of generally vertical spaced posts and a plurality of generally horizontal connecting rails. A countersunk circular aperture is formed through each face of the rectangular posts at a predetermined vertical level. Each of the posts terminates in a ground insertion spike and is of a tubular construction to allow fluid passage. An end face of each of the rails is provided with a central countersunk circular aperture. The countersunk apertures of the rails and the posts each have an inserted resilient bushing. A connecting tube has opposite ends provided with stepped frusto conical ridges for engagement within the resilient bushings to provide a mechanical and fluid connection between the posts and rails. A plurality of spray nozzles include similar frusto conical ridges and may be disposed at selected locations on the posts for irrigating a surrounding area.
