Wastewater Treatment Plant - SCADA System Design, Programming and Start-up

In 2005, AMR installed a SCADA system for a large waste water treatment plant located in eastern Tennessee. The scope of the project included the automation of the plant's influent, treatment phases, and effluent. Listed below are several highlights and parameters of the project, the major equipment that was automated and the major equipment and software AMR utilized in implementing the system.

Project Parameters and Highlights:

  • Complete SCADA system integration utilizing RF wireless communications
  • HMI, SLC, Historian and PanelView programming
  • Design, fabricate, install and start-up control panels
