Project Activity Posts

City of Wyoming Clean Water Plant - Stage 2 Improvements Finished

Erhardt's project at the City of Wyoming's Clean Water Plant involved a major $35.6 million expansion to the wastewater treatment facility, as well as rehabilitation of some of the existing facilities and equipment. The project included: Three new aeration basins, each holding a total of 3.5 million gallons of effluent water. Adjacent to the basins, a blower building and various pipe galleries were constructed. Four new 95-foot diameter final clarifiers, each holding a total of 1 million gallons of effluent water. A new generator building housing two - 2.0 megawatt generators along with auxiliary electrical switchgear and equipment. A new return activated sludge/waste activated sludge pump station. Repair and retrofit four existing primary clarifiers. Replacement of three large raw sewage pumps, including motors and VFD drives. Decommission and demolition of the city’s old trickling filter system. Groundwater was a major obstacle due to the vast size of the project and the water level being just below grade. It was overcome with a team of wells to draw down the groundwater level, and the use of a bentonite slurry wall keyed into the clay layers below grade. Another challenge was integrating the new facilities into the fully functioning wastewater treatment plant without affecting the operation. Various system shut downs, effluent water bypasses, and multiple tie-ins were orchestrated by Erhardt Construction and our subcontractors. Between all of the structures, a total of 25,000 cubic yards of concrete, miles of pipe, conduit, and wire were installed. Supervisors Ben Wickstrom, Project Manager, Matt Smith, Assistant Project Manager and Dave VanderHyde, Project Superintendent. Budget $35,700,000
