Description

The scope of this project is to replace the existing direct bury steam and condensate lines serving Tawanka. The work includes constructing a buried utility tunnel between the existing main tunnel and Tawanka to house the new steam and condensate piping. The new steam and condensate lines will tap into the existing services in the main tunnel, and enter the new utility tunnel through cored holes. Once in the building, the lines will be routed through the first-floor ceiling, and down to the existing steam converter station. Once the new lines are in, the existing steam and condensate lines will be disconnected at both ends, and will be removed or abandon in place as noted.
