U.S. seeks fish pump system valve, channel modification at 810-MW Lower Granite Dam

Lower Granite Dam

The U.S. Army Corps of Engineers bids to replace a currently inaccessible 10-inch valve in the fish pump system of 810-MW Lower Granite Dam on the Snake River in Washington. A site visit is planned April 9 with bids due April 29.

The Corps also seeks bids to modify a juvenile fish collection channel at Lower Granite. A site visit is planned April 10 with bids due April 29.

The Corps' Walla Walla District solicited information in March on firms able to replace the Lower Granite AUD-5 valve, a 10-inch non-rising stem gate valve on the discharge of the unwatering header for fish pumps located inside the powerhouse unwatering sump. Work includes core drilling and installing a new 30-inch access hatch in the ceiling of the unwatering sump in line with the valve, which is stuck partially open. The existing manhole does not allow for direct access to the valve. The government is to supply the new valve.

The work, valued at $100,000 to $250,000, includes an option to replace the AUD-6 valve, an 8-inch butterfly valve.

Bids sought to modify juvenile fish collection channel

The Walla Walla District also seeks bids to modify a juvenile fish collection channel at Lower Granite. It solicited information last year on firms able to perform the work.

The district also took information last year on firms able to upgrade the juvenile fish passage facility at Lower Granite.

The Corps now seeks bids to permanently close juvenile fish collection channel reservoir side fish slots and Wagner horn openings. Closure is to be accomplished by using existing fish slot screens and converting them with concrete into fish slot plugs and by constructing reinforced concrete plugs for the Wagner horns, which are 3-foot-diameter corrugated metal pipe-lined openings. The work is expected to be performed between August 2014 and January 2015 at a cost of $1 million to $5 million.
