There are many types of quality canal and drainage gates available to our customers. These products have been extensively used in private and municipal systems as well as projects of the U.S. Corps of Engineers, U.S. Bureau of Reclamation, and other federal and state departments of conservation and wildlife. Some common types are shown.
Flap gate valves allow outflow of water from a culvert pipe or structure to a body of water but prevent backflow. It is frequently used in reservoirs, tidal basins, ponding basins and storm drain systems. The flap gate allows a stream to drain normally during normal flows but prevent high tides or river floods from backing water up the stream channel.
Aluminum gates are available in several different types of gates. The aluminum material allows for excellent sealing while providing maximum resistance to corrosion. The aluminum construction prevents electrolysis associated with cast iron gates connecting to aluminum pipes, and the lighter weight reduces installation costs.
Ditch gates are most commonly used on ditch turnouts and similar low head operations. They are designed to hold in any position for easy flow regulation, seals positively, slides easily and does not load with sand of silt.
Canal gates are used in open ditch “canals” as isolation and turn-outs. They can also be grouped together to direct flow in some applications. Canal gates are typically equipped with hand wheels but can be electrically operated as well.
Sluice gates are designed for use in controlling flow through round openings with heads up to 20 feet on the front side and up to 10 feet on the back. Flat back models are generally mounted to concrete headwalls while spigot back models are for mounting to our corrugated pipe.
This product uses the same material as the half round pipe. It is available in various degrees of circle in various radii.
For downslope drains, ditch liners, and areaways. Standard 10 foot lengths are furnished match punched with bolts. Also available in two foot increments in .064, .079 and .109 inch thick steel. Aluminum thicknesses are .060, .095 and .105 inch
Same material as above. Available in various degrees of circle in various radii.
Flume has corrugations parallel to the direction of flow and is commonly used to prevent erosion on downslope drains. Standard 10-foot lengths are fabricated from .064 inch thick galvanized steel sheets, furnished match punched with bolts. Sizes are 12 inches x 7 inches, 24 inches x 12 inches, and two piece “Super Flume”, adjustable from 32 inches to 64 inches wide x 12 inches high. Anchor stakes, fittings and several types of entrance adapters are available.
Adapts round pipe to rectangular box flume. 12 inch starter adapts 12 inch flume to 12 inch through 21 inch pipe. 24 inch starter adapts 24 inch flume to 24 inch through 36 inch pipe. Material is .064 inch thick galvanized steel.
Bonnet style end caps may be used to permanently or temporarily cover buried pipe ends or vertical risers. Materials and fabrication details vary with need.
For pipe down drains through roadside berms. Available for pipe sizes 8 inch through 24 inch in .079 inch thick galvanized steel.
Saddle tees are custom fabricated for connection to existing pipe, or field located connections in new construction
These structures are custom fabricated to meet specific project requirements. Manholes, risers, inlets, and outlets are made from CSP, CASP, or CAP in any available thickness. Corrugations may be 2-2/3 inch x ½ inch, 3 inch x 1 inch, or 5 inch x 1 inch. Available with solid cover or open grating, with or without welded bottom. Drop inlets are commonly used to collect surface water and/or for clean outs. Manholes and risers are used for access to underground systems or to connect multiple lines
Permanent or removable grates can be fabricated to prevent unwanted debris or animals from entering the pipe. Grates can be fitted to round pipe, pipe-arches, beveled ends or end sections and may be black steel, painted, or hot dip galvanized.
Discourages burrowing rodents and helps prevent seepage along pipe surface. Available in .064 inch through .138 inch steel and .060 inch through .135 inch aluminum thickness. Collars can be shop welded or field bolted.
Anchor assemblies consist of a band or strap around pipe, anchor stakes, attachment plates, and necessary hardware. One of several types is shown.
Debris racks are used to prevent clogging of pipe inlets by water borne debris. Some common types are shown but many other custom designs can also be fabricated.
