Abstract

An irrigation device designed to change the water flow in the main supply pipe (underground) to different directions for a timed period, then switch back. A timer in a control-box determines the switching cycles. A butterfly-valve actually changes the direction of the water flow, and an extension converts the power applied from the control-box to the valve body. This underground surge irrigation system is designed for furrow flood irrigation and some forms of sprinkler irrigation to increase the efficiency of the water applied, for a more uniform soak profile through the whole field.
