About this file
This document contains plans and specifications for an equipment upgrade to pump stations along the Columbia River in Oregon and Washington. The project involves upgrading electrical equipment at Pump Station 15C, including installing a new manual transfer switch, motor control center, and variable frequency drives on three 50HP pumps. A 400A portable generator will provide backup power via the manual transfer switch. The project also calls for upgrading conductors and installing new conduits and weatherheads. The solicitation number for this opportunity is W912EF23B0002 and it was issued by the Department of the Army Corps of Engineers Walla Walla District. The response is due by September 2023.
