Smart Drainage System®

Smart Drainage System®

By using drainage water management instead of conventional deep free drainage, producers conserve water, reduce fertilizer and nutrient loss to streams by 30 to 50%, and increase yields.

The Smart Drainage System gives users the ability to manage their drainage system, ensuring the proper moisture level for maximum yield, while reducing nutrient loss and risks associated with drought or excessive moisture.


Smart Drainage System® Tips


  • Most cost effective on 0-1% slope.
  • Install mains on steepest grades and laterals as long and on as flat of a grade as possible.
  • Install Water Level Control Structures in the main every 1′ to 2′ of elevation change.
  • Some existing drainage systems can be retrofitted.
  • Can be used to sub-irrigate crops.
  • Cost share available to install and manage Smart Drainage System® in some areas.


Add Multi-Level, Automated, Remote-Control Capabilities


  • Add to Agri Drain Inline Water Level Control Structures, up to 15″ diameter.
  • PVC Slide Gate Valve. (Components slide into tracks of an Inline structure.)
  • Power actuator to open and close the slide gate valve.
  • Water level sensor to monitor water level in the structure.
  • Solar panel and battery to provide power to the system.
  • Programmable controller with cellular/cloud-based communications.
  • Weather-proof enclosure.


Smart Drainage Site Options


  • Monitor and manage your system remotely.
  • Open/close valve on demand or automatically based on desired set-points and a year-round schedule.
  • Smart Drainage Site dashboard displays water level, battery condition, valve position, and set-points.

Typical drainage water management installation with an Inline Water Level Control Structure™.



The Inline Water Level Control Structure™ is designed to be installed in the pipe line, so the water enters the pipe, then flows into the box, over the stoplogs, then out the downstream side of the structure. Structures are available in either manual or automatic.


Manual Structure Features


      • Structures are constructed of rugged 1/2″ PVC.
      • Stainless steel screws and custom anodized aluminum corner extrusions are used for
      • strength and durability.
      • 5″ & 7″ stoplogs for adjustability.
      • Available in 4″ to 24″ diameter pipe.
      • Inline available in 2′, 3′, 4′, 5′, 6′, 8′, 10′, and 12′ heights.
      • Flexible couplers allow PVC, plastic pipe, or other materials to be easily attached (specify when ordering).
      • Larger CMP structures available.
      • 5-year warranty on all standard structures.
      • Customized or special orders will carry a 1-year warranty on workmanship and material and are nonreturnable.
