The Columbia/Snake River system is the largest wheat export gateway in the U.S. Almost half of the wheat exports arrive by barges moving through the Columbia/Snake River system. It is estimated that each year over 3.5M (4.2M in 2020) metric tons of commodities currently move through the lower Snake River locks. The Pacific Northwest Waterways […]
The Greatrock North Water and Sanitation District retained our team to address its aging and failing reverse osmosis water treatment plant. The existing plant designed and built by the original developer had a capacity of 100 gpm and could not keep up with the desired capacity or the district’s water quality targets. The district’s raw […]
The Edgemont Ranch Metropolitan District was issued new and very strict TIN, TN and TP limits that rendered their lagoon system obsolete. Edgemont Ranch lies in the watershed of the Florida River, a tributary of the Animas River. Downstream of the treatment facility are agricultural irrigation reservoirs that experienced algae blooms. Because lagoon-based systems are […]
The Town of Del Norte’s collection system had significant structural issues including collapsed clay pipes, cracks, and offset joints. This caused significant inflow and infiltration (groundwater/runoff) into the collection system, sometimes as much as doubling or tripling the normal influent wastewater flow to the wastewater treatment plant. This significantly affected the treatment facility’s ability to […]
Center Sanitation District was struggling for years with a non-compliant lagoon system. The existing facility had chronic BOD, TIN, and E. Coli violations of their groundwater discharge permit. The district was issued a Notice of Violation Cease and Desist Order for the length and severity of these violations. Our team was tasked with creating a […]
The client was looking for a safer and more efficient way to transfer ore to the main course ore bin. The existing ore dribble chute was scanned in 3D and used to design a new dribble chute and platform. The new dribble chute design changed the location of discharge from a conveyor directly to course […]
Crush/Convey department wanted to implement a new system to lift and convey belt feeder drive motors to a roof opening area. Project objective was to evaluate existing capacity of ceiling beams for trolley and hoist system designed to remove and install belt feeder motors to a roof opening area.

The existing counterweight on the 7B conveyor had a winch system with inadequate lug connections and was rigged at an improper angle, which created structural integrity issues. Bowman calculated the take-up weight on lateral beams to size counterweight box and evaluated counterweight lifting methods compared to the existing winch system. Bowman prepared an economic trade-off […]
