ABSTRACT
You have heard the old saying, “A picture is worth a thousand words.” This is certainly true when referring to wastewater unit processes, plant process machinery, or a plant electrical motor controller. It would be next to impossible for a maintenance supervisor (or any other knowledgeable person) to describe in words the shape, size, configuration, relations of the various components of a machine, or its operation in sufficient detail for a wastewater maintenance operator to troubleshoot the process or machine properly. Blueprints are the universal language used to communicate quickly and accurately the information necessary to understand process operations or to disassemble, service, and reassemble process equipment.
