Abstract

A distributed concentrated chemical dispensing system 300 and method include a central station 302, one or more permanently mounted satellite stations 304, and one or more portable satellite stations 306. Local concentrated chemicals can be distributed from the central station 302 without being diluted to the satellite stations 304, 306 for final dilution. An information storage device 318 is provided for tracking and keeping records of the utilization of the concentrated chemicals.
