Process is the word given to the treatment side of the water industry.  This is primarily divided into Water Treatment & Wastewater Treatment.

Treatment Plants

Process assets are more commonly called “treatment plants”:

  • Water Treatment Plant (WTP)
  • Wastewater Treatment Plant (WwTP)
  • Sewage Treatment Plant (STP)

or “treatment works”:

  • Water Treatment Works (WTW)
  • Wastewater Treatment Works (WwTW)
  • Sewage Treatment Works (STW)

Inside the water industry they are sometimes referred to as “non-infrastructure”, or “above ground assets”.

Process Engineers

The engineers who specialise in this part of the water world tend to be called Process Engineers.  Treatment design is a team sport that requires many others including Civil Engineers, Mechanical Engineers, Electrical Engineers, Instrumentation, Control & Automation Engineers, Cost Consultants, Operators and many more.  Process Engineering is synonymous with Chemical Engineering.  As such, the Process Engineer’s role focuses on physicochemical changes to the water (primarily the removal of contaminants).
