The existing draft tube on unit #3 in Abiquiu has been experiencing wear from cavitation created by the dissolved oxygen injection system. The injection system forces air into the discharge water to enhance the oxygen content of the plant discharge to sustain aquatic life. The injection piping obstructs the discharge flow and creates cavitation that has worn through steel draft tube. These funds will be applied to repair the damaged section of the penstock and install a new aeration intake system.
For a sense of scale, the diameter of the flange on the left in the photo below is 1600mm.
