Inlet Water Level Control Structures™ are designed to control the depth and volume of water within a wetland or pond by removing surface water. Stoplogs can be removed or added to achieve your desired water level height.

  • Constructed of rugged ½" PVC.
  • Stainless steel screws and custom anodized aluminum corner extrusions used for strength and durability*.
  • Flexible coupler allows PVC, plastic pipe, or other materials to be easily attached. (Please specify type of pipe when ordering.)
  • Stoplogs made of PVC in 5" and 7" heights for adjustability. (Maintenance recommended: Remove stoplogs and grease seal with Ultra Lube [included]. Ensure there is no debris in the tracks or along the bottom of the structure. Replace stoplogs after greasing.)
  • To minimize seepage, align stoplogs firmly against one side of the stoplog track.
  • Stoplogs must remain in track during structure installation.
  • Structure must be anchored down when installed or it may have the tendency to float.
  • Structures are intended for gravity flow; some seepage may occur.
  • 5-year warranty on all standard structures.

*For water that is caustic, acid, corrosive, salt, or pH below 5 pH or above 9 pH, please notify us of your requirements to ensure structures are built with compatible hardware. For these applications, Agri Drain recommends stainless steel.
