Inline Water Level Control StructuresTM effectively manage the water table in your field, wetland, pond, and a variety of other applications by setting stoplogs within the structure to your desired water level height. Management allows for controlled release of outlet flow, retention of valuable nutrients, and effective flood mitigation.

  • Available in Manual or Automated.
  • Constructed of rugged ½" PVC with lockable plastic lid.
  • Stainless steel screws and custom anodized aluminum corner extrusions used for strength and durability*.
  • Flexible couplers allows PVC, plastic pipe, or other materials to be easily attached. (Please specify type of pipe when ordering.)
  • Rugged injection molded stoplogs in 5" and 7" heights for adjustability (included in structures with 4" through 12" pipe sizes).
  • PVC stoplogs with metal hooks in 5" and 7" heights for adjustability (included in structures with 15" through 24" pipe sizes). 
  • Stoplog boards are installed in the track of the structure with lifting hooks facing the downstream/outlet side of the structure. 
  • Stoplog 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, ensuring bottom stoplog is installed first.
  • To minimize seepage, align stoplogs firmly against one side of the stoplog track.
  • Stoplogs must remain in track during structure installation.
  • 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.
