Keynote speech at modelling conference  

International recognition for the SIMDEUM simulation model

SIMDEUM is a modelling programme which reveals the patterns of drinking water demand and enables predictions to be made on future demand. The KWR model has been gaining international recognition. This partly explains why KWR researcher and SIMDEUM developer Mirjam Blokker was invited to give a keynote speech at the 16th Water Distribution System Analysis Conference in Bari, Italy. Another consequence of the recognition of Blokker’s expertise is a collaboration between KWR and the University of Sheffield.

“I presented the broad range of SIMDEUM applications to my fellow researchers during my talk,” says Blokker. “I placed particular emphasis on the importance of gaining insight into water demand. Only when you have a clear picture of water demand, can you make statements about the water quality in the distribution network and the sustainable use of drinking water.” What is unique about the SIMDEUM simulation model is its use of external information drawn from sources like surveys and Statistics Netherlands (CBS) data. The model has been applied on a regular basis by KWR researchers since its completion in 2006. Members of the audience at the conference in Italy were noticeably enthusiastic and “indicated that they also want to work with it,” says Blokker.

Visiting professor

The existence of a strong interest in the modelling of water demand is further confirmed by Blokker’s appointment as visiting professor at the University of Sheffield for 2014. The Pennine Water Group, within the university’s Faculty of Civil Engineering, disposes of a well-equipped laboratory. “KWR focuses essentially on practice,” says Blokker. “Thanks to this collaboration, I expect that we’ll be able to delve more deeply into the fundamental processes that are important for the quality of water in the distribution network, and that we’ll be able to apply SIMDEUM more widely. Ultimately, the idea is that, apart from researchers, the drinking water sector and the installation sector will be able to use the model as well.” Blokker anticipates that in 2015 concrete collaboration projects will get underway targeting water quality in drinking water distribution networks and water demand modelling.

Water-Use Info

The SIMDEUM model has also reached the Watershare® platform in the shape of Water-Use Info. In this tool, which gives the user a clear image of drinking water usage, SIMDEUM is equipped with a user-friendly graphic interface. Water consumption patterns can be easily generated and then incorporated into the user’s own models. In the years ahead, it is expected that SIMDEUM will also be available for the indoor installation sector.

Like the other keynote speakers, Mirjam Blokker received a certificate from KWR for her presentation at the Water Distribution System Analysis Conference in Bari, Italy.
