So instead of using crescent shaped siphon tubes which can be easily moved when and where required without damaging the irrigation trench. we need a 30 ft long chain saw mounted on the back of a tractor to cut deep gouges in the berms then lay in straight tubes for the water to flow through each requiring a valve because the tubes must be left in the berm for the entire season then we need a roller to pack dirt on top of the tubes all the while we can only hope that the water does not eventually erode along the tubes and wash out the berm. yeah that really makes sense to me NOT!
