Drinking WaterSimulator for

Proactive Operation and Training



Why Waterspot?

Drinking water treatment operation changes from 24/7 shifts…


Why Waterspot?

... to supervisor shifts in office hours…


Why Waterspot?

... opening opportunities for advanced process control…

... and virtual commissioning…

... but resulting in a lack of natural training at the same time.

Why Waterspot?

The need for well-trained supervisors will stay…

… or even increase in the next ten years as a consequence of ageing.

Why Waterspot? Summary

  • Offline

  • Training and testing of operation supervisors in company look & feel

  • Model-based process (control) optimisation

  • Open the use of process models to a wider group

  • Virtual commissioning of software updates

  • Online

  • Advanced process-control to delay investments in production capacity, and to obtain a more stable water quality

  • Alerts on malfunctioning online measurements


Waterspot: the project

Started on the foundations of the Promocit project (development of Stimela water quality models)

Co-funded by Dutch Ministiry of Economic affairs


Waterspot: the project

Nine partners of which four Dutch water supply companies

Waterspot: software layout

  • A drinking water treatment plant simulator that connects:

  • Models for water quality

  • Models for water quantity

  • Control model

  • Object model

Waterspot: hydraulic model Harderbroek

Calibration: current frequency to control effluent pumps’ speeds



Waterspot: hydraulic model Harderbroek

Validation, cascade aerators


Waterspot: hydraulic model Harderbroek

Validation, influent rapid sand filters


Waterspot: hydraulic model Harderbroek

Case: pump speeds during filter backwash



Waterspot: hydraulic model + process model Wim Mensink

Stimela model for Mensink has been set up.


Waterspot: hydraulic model + process model Wim Mensink

  • Work in progress:

  • Calibration and validation Stimela model

  • Connect EPAnet and Stimela with in Waterspot

  • Simulate hydraulic operation of Mensink
