Location: Berthoud, Colorado
Due to years of siltation, the Town of Berthoud’s water supply was unable to utilize the existing reservoir. WSRI was contracted to clear and grub the work site, construct a bifurcation embankment to capture sediment above the existing dam structure, and revegetate disturbed areas. Due to excess groundwater, this project potentially required a soft subgrade using track hoes and haul trucks. WSRI solved this issue by dewatering and excavating critical areas using scrapers. Approximately 75,000 cubic yards of soil material was stripped and stockpiled from the existing reservoir body; in addition, nearly 37,500 cubic yards of soil material was placed and compacted for the bifurcation dam. Three concrete water-intake structures and associated piping were constructed to convey water from the ineffectual water cell into the potable water cell.
Working within a residential area, WSRI managed dust and noise control to ensure minimal impact to the neighborhood. Upon project completion, the Town of Berthoud contracted a change order to build an additional boat dock and utilize excess PVC piping for a recreational catfish habitat. Both the Town of Berthoud and the residents near the reservoir had positive feedback about WSRI’s quality of work and the manner of time in which it was completed.
