McNary Drainage, Unwatering, and Equalization System Rehab   4

The U.S. Army Corps of Engineers (USACE) Walla Walla District intends to issue a construction solicitation for a project titled McNary Drainage, Unwatering, and Equalization (DUE) System Rehab. The work will take place at McNary Dam in Umatilla County, Oregon.

The McNary Lock and Dam powerhouse drainage, unwatering, and equalization (DUE) system has been in constant operation for 68 years, being installed in 1952. The DUE System consists of three 5,000gpm 200hp vertically mounted centrifugal unwatering pumps, one 3,000gpm 125hp vertical turbine pump and associated discharge piping ranging in size up to 18 inches in diameter. The system also consists of 56 drain valves (2 per main generator unit) ranging in size from 16 to 18 inches in diameter.

The scope of work is to rehab the DUE system. This includes replacing all unwatering and drainage pumps to include all non-embedded intake and discharge piping as well as all isolation valves. Diving in the tailrace will be required to temporary plug the unwatering pump discharge piping while isolation valves are replaced. The three unwatering pumps will be converted from 4160V to 480V with the installation of new transformers and motor control centers. Work within the unwatering and drainage sump will require the setup of temporary pumping to install new pump intakes and seismic bracing.

The blockage in the primary embedded 8-inch drainage header pipe that runs the length of the powerhouse (approx. 1400 feet) will be removed, and the temporary (non-embedded) PVC drainage header removed.

All 56 drain valves are to be replaced. Half of the drain valves are located at the bottom of 30-foot-deep valve pits. Valve work also includes the replacement of stem packing on twenty-six 24-inch equalization valves.
