Abstract: Preferably for irrigation purposes wherein a sloping conveyance includes multiple and like sized orifices aligned therealong in near level relationship to thereby provide diverted water balanced access to the orifices. A uniflow system incorporating sloping supply, downstream valved-riser and orifice line segmentation in relative position whereby selective valve actuation causes a diversion to well-up to and out the orifices simultaneously and thereby cause the automatic distribution of duplicated flow to the land. Actuator assembly mounting automates the diversion. Actuator mounting in communication with a remote controller further automates diversions through systems programming.
