Patent ID: 8403596

Claim:
A groundwater control system for an agricultural field to regulate the level of groundwater in said field according to selected criteria, said system comprising: (a) a buried field drainage tile line extending underground in said field to serve to drain water therefrom; (b) a water flow regulator located in said tile line and having a movable gate that is powered to control the flow of water therethrough; (c) means located in-ground, and exterior to said tile line and said water flow regulator, for sensing the amount of groundwater in said field before the groundwater enters said tile line on at least a periodic basis and for providing output signals representative of said groundwater information, said means for sensing is located exterior of both said drainage tile line and said regulator; (d) processing means programmed with the selected criteria for said groundwater level for receiving said output signals representative of said groundwater information and providing output signals to said flow regulator to control the position of said gate for meeting said selected criteria; and (e) a communication link linking said processing means, said means for sensing the amount of groundwater, and said flow regulator, said link comprising satellite receiving and transmitting means.
