Abstract
A drinking water distribution reservoir has a new draft tube mixing arrangement. An intermediate opening in the draft tube enables water to flow between the central passage of the draft tube and an intermediate portion of the tank. Directional walls can be provided on the intermediate opening to help direct flow, and a check valve can be used to prevent flow from the intermediate section of the tank into the draft tube or prevent flow from the draft tube into the intermediate section of the tank. A venturi portion can also be provided on the draft tube to help draw water from the intermediate portion of the tank into the draft tube.
