An apparatus and method for dispensing fluid to large numbers of people are disclosed. One embodiment of a portable apparatus for treating and dispensing fluid includes a housing that is fluidly attached to a fluid source. Several fluid delivery components are disposed within the housing to dispense fluid to a user. The fluid delivery components may include a pressure regulator, a backflow preventer, filters, cooling misters and dispensing valves such that the such that the fluid source integrity is protected, the fluid purity is improved, and the air within the housing is cooled which in turn provides cooling to the fluid delivery components and the fluid itself. This embodiment also includes a mechanism for providing ballast in the lower portion of the housing in order to stabilize the device and keep it from moving when bumped into by people (accidentally or intentionally) or in windy conditions, and a mechanism to empty the ballast for removal of the system.
