Archer Western powers ahead on the expansion of Arcadia Lake WTP
Edmond, Oklahoma - Archer Western powers ahead on the $191 million expansion of the Arcadia Lake Water Treatment Plant. The City of Edmond reports approximately 70% of the underground concrete has been placed for the new high lift pump station that will pump treated water to the city residents and businesses. The granular activated carbon (GAC) filter building slab pours are being completed and the walls are being formed. The GAC filters will reduce the potential for disinfection byproducts when chlorine is added to the water.
Both of the four-million-gallon clearwell tank concrete floors, interior baffle walls, exterior walls and dome are placed, with work continuing on the exterior concrete coating. The recycle pump station steel piles have been driven for structural support, and crews are excavating the lower wetwell section to start placing structural concrete in the next couple of months.
