Mirjam Blokker PhD

  • Principal scientist

Mirjam Blokker is a principal scientist on the drinking water infrastructure team. She is an expert in drinking water demand and developed the SIMDEUM model, which can be used to predict the demand for shower water, toilet flushing water, water consumption etc. With this model, she also did research on the impact of flow speeds and residence times on water quality in the pipeline network and completed her PhD on that topic in 2010. As an extension to this, Mirjam carried out the research and implementation in designing the water network. In recent years, Mirjam researched the temperature in the pipeline network and the microbiological regrowth in the network. In collaboration with her colleagues on the microbiology team, Mirjam developed models for quantitative microbiological risk analysis (QMRA) for collection, purification and in the distribution network. Mirjam’s knowledge of statistics came in rather handy in her research on pipeline, valve and fire hydrant failure. Mirjam also stood at the forefront of the introduction of the performance indicator for inadequate supply minutes (OLM). Mirjam owns a few Watershare tools. Mirjam is visiting professor at the University of Sheffield (UK), in Professor Joby Boxall’s group.
