Howes Dam & Buffalo Dam Dewatering
Owner: South Dakota Department of Transportation
This project involved the emergency dewatering of two dams located on Hwy 34 east of Howes, SD. Excessive rains had fallen in the area filling the dams beyond their safe capacity. Along with this, the overflow pipes had failed on both Dams and the earthen dams were eroding fast, and being compromised to a point near failure.
We mobilized to the sites and set up a temporary dewatering system that allowed the water levels in the dams to be lowered to safe levels while the overflow pipes were repaired.
Work was completed in less than one week
Mainline's crew that was assigned to our project were professional throughout the project and assured that the City's expectations were met and exceeded. In spite of numerous project challenges which included confined site conditions, groundwater/creek seepage, dep bore pits, large cobble to bore through and period of extreme cold weather, Mainline Contracting completed the project with quality workmanship, on time and on budget.
Last summer we had the experience of reconstruction on our street. Fortunately for the city, Mainline Construction and Complete Concrete made it as painless as possible. I hope the city continues to use these two fine companies often.
Mainline Contracting made an outstanding effort to exceed compliance expectations for the installation of the drainage improvements, crossings and box culverts for the Back 9 holes at the Elkhorn Ridge Golf Course. The site compliance record at this time is outstanding and is clearly a result of good team effort.
Mainline Contracting Inc did an excellent job working with the residents affected by the project and providing the resources required to overcome the harsh weather conditions. They kept a positive attitude and were able to meet the substantial completion date set for the project without sacrificing the quality or workmanship of the construction.
