Finley Pump Station, Forebay Sediment Removal
January , 2011
Approximately twelve (12) feet of sediment has built up in front of intake structure of the Agrium Finley Pump Station located on the Columbia River in Kennewick, WA. Divers used a suction pump to pump the sediment / water slurry from the forebay area to an upland location for disposal. Divers operated from a dive trailer located on shore adjacent to forebay area. The suction pump was located on the adjacent pump deck; a booster pump was in line to assist in moving the sediment / water slurry the long distance to the disposal location.
