ABSTRACT:
A riser assembly for a sub-surface irrigation and drainage system is disclosed having a molded, housing defining a generally rectangular, elongated cavity. A divider within the housing divides the cavity into an upstream chamber and a downstream chamber. A drainage opening and a weir opening are defined by the divider, and slidable gate valves are disposed over each opening. By adjusting the positions of the gate valves, the upstream water level cable may be readily adjusted.
