WM-Subsurface Software

WM-Subsurface (formerly known as Farm Works Surface) is farm drainage software that works with the Trimble® WM-Drain™ farm drainage solution. WM-Subsurface ensures the optimal placement of tile and surface drains in both surface and sub-surface drainage water management projects, helping to drain fields adequately and increase crop yields. Easily overlay other layers such as yield or soil types to help visualize the field from different perspectives.

The farm drainage software installs on desktop computers utilizing Microsoft® Windows® XP or higher.

Automatic pipe sizing feature for farm drainage software

Automatic Pipe Sizing

Calculate the recommended pipe size for all pipes within a given design, as well as generate an estimate on total cost and material required for the drainage project.  Automatic pipe sizing helps you quickly and efficiently produce optimal drainage designs while reducing your overall costs.

  • Allow your farm drainage software to determine the various watershed zones of the field to assist with main, submain, and lateral pipe placement.
  • Enable flow arrows and tributary lines to assist with tracing the natural surface water flows.
  • Utilize the drawing tools to tie laterals to mains, create parallel lateral spacings, and clip drainage lines.
  • Layout and design drainage tile by size, pipe type, phase, then enter the minimum depth, maximum depth, and optimum grade for each.
  • Utilize the design check feature to confirm that all drainage lines flow correctly.
  • Easily make design adjustments based on vertical profile and set or change direction of water outlet.
  • Create levee paths from topography data based on contour, interval, and turn radius settings.
“We highly recommend WM-Subsurface for the layout of field tile.  Designs that used to take us days using a laser, now are completed with minutes or hours.” Andrew Zimmerman

“The software is able to track exactly how much slope is on the pipe, and how many acres are coming in each line, so I am able to do a very accurate job of sizing the system and do it very quickly.”
