Agricultural tile drainage workshop Feb. 3 at NDSU

The annual University of Minnesota Extension Drainage Design Workshop will be Feb. 3 in the Memorial Union at North Dakota State University.

The workshop is a collaborative effort between the U of M Extension and NDSU Extension Service.

“The spring of 2009 will be remembered for many years for the record flooding that took place in many parts of North Dakota and northwestern Minnesota,” says Tom Scherer, NDSU Extension Service agricultural engineer. “The persistent flooding, along with spring rains, resulted in almost 2 million unplanted acres in North Dakota alone. As a result, many farmers became interested in controlling high water tables or excess water using subsurface drainage.”

The workshop will focus on the planning and design of tile drainage systems for farm fields. It is intended for anyone who wants a more complete understanding of the design principles and practices of tile drainage systems.

The workshop should be of interest to farmers, landowners, consultants, tiling contractors, government agency staff and water resource managers.

The event will start at 8 a.m. and end about 4:30 p.m.

The workshop will feature educational presentations and several problem-solving examples that cover basic design and layout principles, water flow calculations, tile spacing, sizing, tile grades, topographical constraints and lift station design. The format is intended to be hands-on with lots of discussion time.

The registration fee is $100 and includes lunch, course materials, refreshments and a parking pass. Class size will be limited to 40 participants and preregistration is required. Participants must register online (early bird registration by noon, Jan. 25) at the U of M drainage Web site at www.
