Northwest Pump provided the design, equipment, fabrication and installation for the replacement of three outdated failing sewage lift stations for the PGE Beaver Generating Plant in Clatskanie, Ore.
Each lift station was completed within an eight to 10 hour work day so as not to disrupt the plant’s operations. Work was completed after much planning, as the site is remote and required many safety meetings, amongst other requirements. The complete demolition of the old equipment and installation of the new equipment occurred in three days.
The design of the guide rail system allowed for a safer and less intrusive installation of the Quick Disconnect Elbows to the bottom of the lift station. Base elbows, piping and valves were pre-assembled and then mounted to a common stainless steel plate. This assembly was then lowered as a complete unit in the water well.
New custom stainless steel hatch covers and control panels also were installed with extended vent pipe. The extended pipe prevents personnel from being overwhelmed with odors from the lift station.
