New Technologies for Drainage Water Management and Subsurface Irrigation


Published on

For more: Drainage water management is a practice that has been around for years. When a farmer sees a drain tile running, even though it hasn’t rained for a month, he must ask himself, “Why?”. In the past, plugging the tile was an option. This was effective but problems could occur if the plug was not removed after a heavy rainfall.

For over 35 years, Agri Drain Corporation has manufactured and supplied products for water management. These products have evolved, and today, are used for the implementation of drainage water management and subsurface irrigation.

Agri Drain’s Water Level Control Structures are well known as a device used to manage the water table without plugging the tile. Agri Drain recently introduced the “Water Gate”, a float activated head pressure valve. The Water Gate is used in conjunction with a Water Level Control Structure, allowing drainage water management to be utilized on ground that may not have been viable in the past.

The benefit of Drainage Water Management is twofold, a potential yield increase and nutrient retention, resulting in improved water quality. We will explain how both these goals can be met, benefiting the farmer and the environment.
