About this file
This document is the plans and specifications for upgrading the pumps at the McNary Lock and Dam Levee Drainage Pump Station in Oregon and Washington. The project involves replacing three existing pumps at Pump Station 2C to match the existing mounting arrangement and interface with the electrical and discharge piping systems. The new pumps must be compatible with the provided electrical control system and pass through the existing floor opening, which is approximately 5 feet in diameter. Dimensions for the existing pump mounting holes and configuration are provided to ensure the new pumps can be directly installed without modifications. Additional requirements specified include pressure transducers, gauges, access hatches and control setpoints. The solicitation number for this project is W912EF23B0002, issued by the US Army Corps of Engineers Walla Walla District.
