Precon’s Inlet/Turnout Structure is an engineered structure consisting of a headwall and basin designed for water inlet and outlet control. The structure is exceptionally easy to handle and install and the unique design of the headwall acts as an anchoring system as well as a seepage barrier. The Inlet/Turnout is ideal for industrial and farm turnouts or pond inlets. This structure compliments Precon's Check and Check/Drop structures, creating a system that allows efficient access to a water conveyance system.
The Inlet/Turnout is designed based on the shape of the canal or existing topography, flow required, and pipe size. Several different types of accessories (eg. 86 or 150 psi Spools) can also be cast into the headwall which can accommodate numerous gates, pipe flanges and valves with a variety of bolt hole patterns (eg. Sluice gates, Flap gates and 86 or 150 psi connection Flanges).
