1. A method for operating a fluid additive control system to inject a fluid additive into a fluid dispensation system comprising:

  • receiving a first control signal indicating that a fluid dispensation device within the fluid dispensation system is active;

    determining a fluid additive quantity based upon the identity of the fluid dispensation device;

    activating a fluid additive injection system, wherein the fluid additive injection system injects the fluid additive into the fluid dispensation system in response to the activation;

    receiving a second control signal from the fluid additive injection system when the fluid additive quantity for the fluid dispensation device has been injected into the fluid dispensation system; and

    deactivating the fluid additive injection system in response to the second control signal,wherein activating the fluid additive injection system comprises activating a valve coupled to a pressurized fluid;

    wherein activating the valve comprises receiving pressurized fluid from a pressurized fluid supply and transmitting the pressurized fluid into a piston cylinder coupled with a piston; and

    wherein the pressurized fluid moves the piston from an initial position, injecting fluid additive into the fluid dispensation system in response to the pressurized fluid entering the piston cylinder.
