00The inlet was constructed "in the wet" by employing a 35- by 46- foot steel cofferdam with a design height in excess of 70 feet. The connection from the tunnel to the bell-mouth inlet was made using a raise-driven pilot method, allowing excavated material to be removed through the tunnel.
00The outlet consisted of a cast-in-place concrete building that provides housing for a bifurcation, two sets of flow control valves, energy dissipation chambers, and all associated electrical and mechanical controls. The main discharge valve will be a 72-inch diameter fixed cone valve with and upstream shut-off gate valve.
