northeast ohio | The OSU CFAES Campus at Wooster, OH has one field of about 15 acres with the automated Smart Drainage System control structure and three underground “float valve” structures. The tile was installed in 2019, so there have been several soybean and corn crops since. In 2019, a leak to an old main was found and plugged. Since then the system has functioned as intended even though the control structure has been completely under water at least once per year.
As mentioned, it takes a significant rain to fill the system in the summer. I think it’s about 2” to 2.5” from empty to a 18” set point or over 3” to begin flowing over the v notch block. With real time monitoring and control, the settings allow for draining of any surface water in 24-36 hours, but then gradually work down to the set point where the valve remains closed. When it does open the water is very clear. Not sure about sedimentation concerns. What’s very interested is how fast an August soybean crop can drink down the retained water. Hopefully it’s ok to post a screen image of field performance from soybean crop in 2022.
