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 water demand for showers, toilet-flushing, consumption, etc. She also used this model in her research on the impact of flow speeds and residence times on water quality in the pipeline network, and completed her PhD on this subject in 2010. Following upon this, Mirjam did research and implementation work on water network design. In recent years, she has also investigated temperatures and microbial regrowth in pipeline networks. In collaboration with colleagues from the Microbiology team, Mirjam has also developed models for quantitative microbiological risk analysis (QMRA) in water abstraction and treatment, as well as in the distribution network. Mirjam’s knowledge of statistics came in handy in her research on pipeline, valve and fire-hydrant failure. She was also a pioneer in the introduction of the performance indicator for inadequate supply minutes (CLM), and she is the owner of several Watershare tools. Moreover, one day a week, Mirjam is associate professor in the Water Management department of TU Delft. Lastly, Mirjam chairs the expert group on Sanitary Techniques of the TVVL.
