1. A system for formulating a chemical solution by combining water with at least one component concentrate, the system comprising:

  • a storage tank for storing the at least one component concentrate;

    an output port operable to receive the water from a water source and the at least one component concentrate from the storage tank and dispense the water and the at least one component concentrate to a solution container for forming the chemical solution therein;

    a flow meter operable to measure volumetric readings representing a volume of the water communicated between the water source and the output port;

    a weight measuring device operable to measure weight readings representing an actual weight of the at least one component concentrate contained in the storage tank; and

    a controller operable to control supply of the water and the at least one component concentrate to the output port based on the volumetric readings and the weight readings to form a specified amount of the chemical solution.
