96-inch pipeline to be built for East Devils Lake outlet


Gov. Jack Dalrymple announced yesterday that the State Water Commission opened bids for the procurement of pipe that will be used for the construction of the East Devils Lake Outlet, the second state outlet to be built to alleviate flooding in the Devils Lake Basin. The total capacity of the two outlets will remove 600 cubic feet of water per second (cfs) from Devils Lake.

Four bids were submitted to supply pipe for the construction project. The apparent low bidder for the steel piping is Northwest Pipe Company located in Texas and the apparent low bidder for the concrete piping is Cretex Concrete Products Midwest. The State Water Commission staff and engineering consultants will now review the bids and make recommendations to the Commission.

“We need to do all we can to keep the construction of the east-end outlet on schedule,” Dalrymple said. “The opening of the bids and the selection of key suppliers is an important step forward in constructing the outlet and expanding our capabilities to remove water from the lake and alleviate flooding in the Devils Lake Basin.”

Dalrymple has approved two executive orders that allow the State Water Commission to expedite the construction of an east-end outlet and the construction of a control structure at Tolna Coulee. The executive orders suspend requirements specific to any engineering, construction and procurement contracts needed to design and build the outlet.

The State Water Commission has been working with Bartlett & West/AECOM to design the outlet and expects to begin construction this summer. Plans for an east-end water outlet call for constructing an underground, 96-inch pipeline from East Devils Lake to the downstream side of Tolna Coulee. The pump-flow pipeline will be capable of transferring 350 cfs from Devils Lake into the Sheyenne River.

From East Devils Lake, the pipeline will run about five miles southeast to Tolna Coulee.  The outlet and pipeline project allows for winter construction and is scheduled for completion in the spring of 2012.  The project is expected to cost between $75 million and $85 million.

The East Devils Lake Outlet is part of a larger strategy to alleviate flooding in the Devils Lake Basin and to protect downstream interests. In addition to building an east-end outlet, the state is moving forward with plans to build a water control structure at Tolna Coulee. The current west-end outlet began operating last week.
