An aerator for a water treatment plant or water conditioning application, includes a draft tube for vertical positioning within a volume of water and an outlet structure overlying a top open end of the draft tube. Water is lifted or pumped through the draft tube out of the top open end. The outlet structure includes a stepped splash plate which deflects the water flowing out of the top open end in a cascading fashion which increases the oxygenation efficiency and spray pattern of the thus aerated water. Additionally, a blinder bracket is applied to the outlet structure to reduce flow from the outlet structure at a particular preselected arc. The draft tube and outlet structure can be molded as a unitary plastic piece, and flow windows and openings can be cut into the piece.
