This project includes construction of two new 24” intake water lines 250 feet into the rock riverbed. This installation required the installation of a temporary coffer dam to allow construction activities in the river. A new onshore concrete vault was constructed to provide coordinated water feeds to the plant for these two new lines and the three existing lines. Special compressed air equipment and air piping to the new water intake structure provides assurance that the intake structure screen can be cleaned and also provide air circulation to avoid system freezing during extremely cold temperatures.
