Abstract
In a drinking water reservoir, a draft tube is positioned above an inlet pipe to carry fresh water and water stored in a lower reservoir portion to an upper reservoir portion where the drinking water is mixed and stagnation of the reservoir contents is reduced. The draft tube can be used with a recycling pump and/or a mechanism for providing compressed gas to create a gas lifter to mix water in the lower storage portion with water in the upper storage portion when fresh water is not being added.
