Since 1993, wet conditions have brought water from the upper reaches of this watershed down to the Michigan Spillway Project area. The Nelson County Water Resource District Board has worked toward emergency pumping to lower this flood for many years. This project has had many designs made, with protection for downstream impacts and even concerns of invasive species downstream that could migrate upstream. Hence, a very elaborate pump station is required to control these issues for this project and was permitted. The project had a time line completion of December 1, 2014 to mid-2015.
TrueNorth Steel provided a run of CSP totaling 5700 linear feet of 72” diameter (81” x 59”) arched storm drain, which was designed to accommodate a section of the project where soil conditions were not conducive to open channel ditch construction. Access points were placed every 400’ for ventilation and cleanout. 48’ pipe sections were supplied to accommodate contractors request to reduce freight, joint connections and equipment limitations. Aluminized Type ll steel was selected to provide an extended service life.
