Water is supplied through the PVC main (blue) to the Tile mains (red).  The water then travels down grade through the laterals (black).  Drainage water is moved through the laterals to the drains (green) and finally to the drainage ditch or retention system.  Irrigation zones are generally around 10 acres increasing uniformity and control.  Drainage control boxes are located on the drain lines and are used to regulate the water level in the soil profile.

Control structures are installed on the drains allowing for the regulation of the water table in a stair step fashion.  Portions of the stoplogs can be removed or added to adjust the water level.

ˇ Increased yields

ˇ Decreases water consumption

ˇ Reduces Labor, fuel, and maintenance costs

ˇ Improves Pesticide and fertilizer efficiency

ˇ Prevents erosion and surface runoff

ˇ Allows for crop rotation without expensive irrigation adjustments

"Specializing in Subsurface 
Irrigation & Drainage"Systems

Agricultural Water Solutions subsurface irrigation and drainage systems are designed to provide the producer with total soil moisture control. 

Through the use of perforated underground conduits (drain tile) irrigation water is delivered directly to the soil profile.  During periods of excessive precipitation the same system is designed to drain water from the root zone, then hold and maintain optimal soil moisture.   

ˇ A subsurface system is the only irrigation model that provides total soil moisture control whether irrigating or draining.

ˇ Supply valve and mainline for each 7 to 12 acre zone providing maximum control.

ˇ Gravity flow of water is maintained throughout the entire system, this increases uniformity and reduces energy consumption.

ˇ AWS systems are guaranteed to meet all USDA standards, we also offer assistance with the cost share process.

ˇ Every system is designed by growers for growers.
