Drinking Water Simulator for
Proactive Operation and Training
to disclose models
Why Waterspot?
Drinking water treatment operation changes from 24/7 shifts…
... to supervisor shifts in office hours…
Why Waterspot?
... opening opportunities for advanced process control…

... 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
