Roux evaluated over 15,000 linear feet of aging storm sewer conveyance system throughout the 50-acre active facility to assess inflow and infiltration of shallow PCB-impacted groundwater. Over 800 linear feet of PVC storm sewer pipe and 1,700 linear feet of Cast-In-Place Piping (CIPP) was installed. In addition, Roux designed and constructed two oil/water separator (OWS) systems to increase stormwater treatment capacity in order to meet a stringent PCB discharge limits. A 25,000-gallon OWS unit and a 50,000 gallon OWS unit were installed with a combined flow rate of 7,500 gallons per minute.
