George Mesman specialises in drinking water distribution, distribution techniques and pipeline materials in the distribution network. For the design and management of the distribution network, he uses the possibilities provided by the pipeline network calculation programmes Infoworks and EPANET. George has extensive experience building pipeline network models, applying these and the analyses needed to solve the research problems. Self-cleaning pipeline networks and cleaning programmes for distribution networks are subjects for which George Mesman ensures knowledge transfer to the water pipeline companies. Knowledge rules for the application of the pipeline materials PVC and PE were developed in collaboration with the water sector. Damage analyses of ruptures in drinking water pipes is another interesting subject for which George passionately researches the causes and effects. Ruptures in the pipeline materials PVC, PE, Eternit, fibreglass, concrete and steel all have causes in age, location environment, operational management and material properties. Knowledge development by means of researching the ruptures or the combination of these factors helps to accurately evaluate the various materials.
